I don't understand, I have no errors in eclipse, I think the .jar is in maven depences
If you would like to stay in spring boot space just set the pom packaging to jar
<packaging>jar</packaging>
and add the spring-boot-maven-plugin to you build properties in the pom.xml file:
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
then a simple mvn package command will create a complete executable jar file.
See the very good spring reference doc for more details (doing it gradle style also)
spring reference doc
Your jar does not contain the dependencies such as spring-boot which it is looking for during runtime. You can build a consolidated jar with all the dependencies as outlined in this question.
If you are running spring cloud application, make sure your boot version matches
cloud version. You can check the version compatibility matrix at the bottom of this page : https://spring.io/projects/spring-cloud.
Mine was caused by a corrupt Maven repository.
I deleted everything under C:\Users\<me>\.m2\repository.
Then did an Eclipse Maven Update, and it worked first time.
So it was simply spring-boot.jar got corrupted.
The answer to the above question is "none of the above". When you download new STS it won't support the old Spring Boot parent version. Just update parent version with latest comes with STS it will work.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.8.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
If you have problem getting the latest, just create a new Spring Starter Project.
Go to File->New->Spring Start Project and create a demo project you will get the latest parent version, change your version with that all will work. I do this every time I change STS.
Clean your maven cache and rerun:
mvn dependency:purge-local-repository
Here the packaging is jar type, hence you need to use manifest plugin, in order to add dependencies into the Manifest.mf
The problem here is that maven could find the dependencies in pom file and compile the source code and create the output jar. But when executing the jar, manifest.mf file contains no details of dependencies. Hence you got this error. This is a case of classpath errors.
Here you can find the details on how to do it.
Another option is to use the Apache Maven Shade Plugin:
This plugin provides the capability to package the artifact in an uber-jar, including its dependencies and to shade - i.e. rename - the packages of some of the dependencies.
add this to your build plugins section
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
</plugin>
May be your dependencies not build correctly. Check compilation issue in project.
Clean and rebuild project.
For maven project:
mvn clean install
For gradle projects:
gradle clean build or gradlew clean build
Adding below to pom.xml solved my problem
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
I had the same problem and tried most of the solutions suggested above, but none worked for me. Eventually, I rebuild my entire com.springframework (maven) repository (by simply deleting .m2/org/springworkframework directory).
It worked for me.
In my case, I did remove maven nature manually from .project file while having the project opened in Eclipse. So what I'd to do was to add maven nature again using the contextual menu (roght click on the project > configuration > add maven nature). Afterwards, everything worked nice :D
Clearing metadata helped me or change the workspace.
You need to also copy the required dependencies next to your resulting jar and include them in the classpath. An alternative is to use maven-shade-plugin.
Snippet for the first option:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>3.3.0</version>
<executions>
<execution>
<phase>initialize</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<overWriteReleases>false</overWriteReleases>
<includeScope>runtime</includeScope>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
....
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.2.2</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>your.class</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
In my case, I followed these steps
Clean your .m2 folder in your c:/users/your-host-name/.m2
Ensure your pom.xml has this for the buile
org.springframework.boot
spring-boot-maven-plugin
3.0.1
Update your maven, in IntelliJ, this is done by clicking
[![enter image description here][1]][1]
Finally, build your jar by using the Maven package button

I have a project which works perfectly on eclipse, but when I try to run it on terminal using jar file then I get an error. Basically, the aim is to create a fat jar with all dependencies included.

Error: Invalid or corrupt jarfile target/NLPAnnotationController-jar-with-dependencies.jar
As suggested in a comment, double-check to see if the JAR file is really corrupt using jar tv <filename.jar>.
There are a couple of common causes for corrupt JAR files:
The file was corrupted by copying / transferring it the wrong way; e.g. using FTP in ASCII rather than BINARY mode.
The file system filled up while you were writing the file.
This is the ZIP64 problem. The original ZIP file format did not support more than 4GB in size. This was addressed by an extension to the format, but versions of Java prior to Java 7 did not support that.
Reference: https://blogs.oracle.com/xuemingshen/entry/zip64_support_for_4g_zipfile
There is a hard limit of 65535 entries in a ZIP file. Unfortunately, some Maven plugins does not entirely understand this limit. When you attempt to generate a JAR with too many entries, the result is a corrupt JAR file.
References:
Invalid or corrupt JAR File built by Maven shade plugin
Create a large zip assembly with maven-assembly-plugin
The first three explanations are unlikely in your case, for various reasons. That leaves a Maven plugin problem. One of the Q&As that I found said that this was fixed in version 2.5 of the maven-assembly-plugin. But you appear to be using a later version. So maybe this is not the problem after all.
Anyhow:
Check that you are using a Java 7 or later JRE or JDK on your build and execution platforms.
Try updating the version of the maven assembly plugin in your POM to the latest available.

Afterwards, I have gotten a file MyProject-0.0.1-SNAPSHOT.jar in the target directory of the project. Double clicking on that jar in Eclipse gave me a pop-up Windows window saying "Java Virtual Machine Launcher - A java Exception has occured!". To find more about what a possible problem could be, I have copied that jar on the desktop and run java -jar MyProject-0.0.1-SNAPSHOT.jar from that. After that, I got a following error:
Assuming from the error log, I tried to search if I have included org.hibernate.cfg.NamingStrategy in my Maven repository, and yes, I do have it there. After that I got stuck. Any ideas? Thanks.
You need to create an executable fat jar: one that contains your jar dependencies as well. See: Building a fat jar using maven
You have to include all the dependencies on the classpath that are required by your code.
You can naively do this with a shell script that manually adds everything to java -cp parameter, but this is brittle and a complete fail when something changes.
The simplest way to do this is to use the shade plugin to make an uber-jar that includes all the dependencies.
Note that this won't work correctly if any of the dependencies are cryptographically signed, unfortunately the signing stuff is in the MANIFEST file in such a way that it applies globally to the entire .jar and not individual classes or packages. You would have to manually remove the signatures from the uber jar.

I don't understand, I have no errors in eclipse, I think the .jar is in maven depences
If you would like to stay in spring boot space just set the pom packaging to jar
<packaging>jar</packaging>
and add the spring-boot-maven-plugin to you build properties in the pom.xml file:
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
then a simple mvn package command will create a complete executable jar file.
See the very good spring reference doc for more details (doing it gradle style also)
spring reference doc
Your jar does not contain the dependencies such as spring-boot which it is looking for during runtime. You can build a consolidated jar with all the dependencies as outlined in this question.
If you are running spring cloud application, make sure your boot version matches
cloud version. You can check the version compatibility matrix at the bottom of this page : https://spring.io/projects/spring-cloud.
Mine was caused by a corrupt Maven repository.
I deleted everything under C:\Users\<me>\.m2\repository.
Then did an Eclipse Maven Update, and it worked first time.
So it was simply spring-boot.jar got corrupted.
The answer to the above question is "none of the above". When you download new STS it won't support the old Spring Boot parent version. Just update parent version with latest comes with STS it will work.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.8.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
If you have problem getting the latest, just create a new Spring Starter Project.
Go to File->New->Spring Start Project and create a demo project you will get the latest parent version, change your version with that all will work. I do this every time I change STS.
Clean your maven cache and rerun:
mvn dependency:purge-local-repository
Here the packaging is jar type, hence you need to use manifest plugin, in order to add dependencies into the Manifest.mf
The problem here is that maven could find the dependencies in pom file and compile the source code and create the output jar. But when executing the jar, manifest.mf file contains no details of dependencies. Hence you got this error. This is a case of classpath errors.
Here you can find the details on how to do it.
Another option is to use the Apache Maven Shade Plugin:
This plugin provides the capability to package the artifact in an uber-jar, including its dependencies and to shade - i.e. rename - the packages of some of the dependencies.
add this to your build plugins section
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
</plugin>
May be your dependencies not build correctly. Check compilation issue in project.
Clean and rebuild project.
For maven project:
mvn clean install
For gradle projects:
gradle clean build or gradlew clean build
Adding below to pom.xml solved my problem
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
I had the same problem and tried most of the solutions suggested above, but none worked for me. Eventually, I rebuild my entire com.springframework (maven) repository (by simply deleting .m2/org/springworkframework directory).
It worked for me.
In my case, I did remove maven nature manually from .project file while having the project opened in Eclipse. So what I'd to do was to add maven nature again using the contextual menu (roght click on the project > configuration > add maven nature). Afterwards, everything worked nice :D
Clearing metadata helped me or change the workspace.
You need to also copy the required dependencies next to your resulting jar and include them in the classpath. An alternative is to use maven-shade-plugin.
Snippet for the first option:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>3.3.0</version>
<executions>
<execution>
<phase>initialize</phase>

<configuration>
<overWriteReleases>false</overWriteReleases>

<outputDirectory>${project.build.directory}/lib</outputDirectory>

<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>your.class</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
In my case, I followed these steps
Clean your .m2 folder in your c:/users/your-host-name/.m2
Ensure your pom.xml has this for the buile
org.springframework.boot
spring-boot-maven-plugin
3.0.1
Update your maven, in IntelliJ, this is done by clicking

Finally, build your jar by using the Maven package button
I've an application that uses Maven to build a JAR with the maven-assembly-plugin.
The project includes a list of dependencies and one of these is another Maven project.
I'm developing with Eclipse and when I run the project everything works fine. When I build with the Maven goal assembly:assembly, it makes the JAR but when I run the JAR it gives me this error:

The problem is related to the Java mail dependency. As you can see I've used com.sun.mail but I saw some other different libraries that correspond to javax.mail.
Maybe I'm missing something in my poms, such as configuration parameters or plugins.
I've also tried to put in my local repository a mail.jar that works fine in other projects but I get the same error.
The "Unresolved compilation problem" comes from a class file in your utils project that Eclipse has compiled, but where Eclipse was unable to compile it properly.
The reason you are seeing different results from Eclipse and Maven is that they are using different versions of the class file. Eclipse is doing workspace resolution, so it's using the version of SMTPMailService in utils/target/classes. Maven is resolving the utils jar from your local Maven repository, which was put there by running mvn install while you had compile errors in Eclipse.
Try running mvn clean install in the utils project (clean to remove any class files generated by Eclipse, install to replace the jar in your local repository). Then rebuild your assembly.
basically what I have is an application server running liferay portal.
and we also have custom portlets that have shared custom libraries as well as third party ones.
for instance dwr-3.0, several drools jar files, spring-webmvc, spring, etc.
the problem is that is a nightmare for server administration, because when there is a deploy somebody always forgets what version was in the server etc.
We use maven 2, and what I was thinking is to do something like a maven project that pulls the dependencies (using dependencyManagement) from the parent pom and the default goal is something like "unjar all the dependencies and jar them in a unique jar".
that way we would have a unique jar with a standard version that is deployed along with the rest of the files instead of having to deploy.
Do you guys know how can I do that if it is at all possible?
I have been playing around with maven-assembly-plugin without much success. If assembly is the way to go, do you have an example to give me a kickstart?
Thanks in advance
Another alternative is the maven-shade-plugin or even jarjar. I've used both, together with package renaming without any problems.
It sounds like maybe the Dependency Plugin is what you need.
I'm thinking you can unpack all the dependency jars to a specified location, then repack them into your new jar.
I hope it works out for you.
I think that what you described is possible. First, create a parent POM where you declare dependencies in the <dependencyManagement> element:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>groupIdA<groupId>
<artifactId>parent</artifactId>
<packaging>pom<packaging>
<version>1-SNAPSHOT</version>
...
<dependencyManagement>
<!-- Standard dependencies used in several build modules. Ensures all modules
use the same version for these dependencies -->
<dependencies>
<dependency>
<groupId>org.directwebremoting</groupId>
<artifactId>dwr</artifactId>
<version>3.0.M1</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>3.0.0.RELEASE</version>
</dependency>
...
</dependencies>
<dependencyManagement>
...
</project>
Then, in a child project, declare the dependencies you need without declaring their version:
<project>
<modelVersion>4.0.0</modelVersion>
<parent>
<artifactId>parent</artifactId>
<groupId>groupIdA</groupId>
<version>1-SNAPSHOT</version>
</parent>
<artifactId>childB</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>jar</packaging>
<dependencies>
<dependency>
<groupId>org.directwebremoting</groupId>
<artifactId>dwr</artifactId>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
</dependency>
...
</dependencies>
...
</project>
Finally, use the default jar-with-dependencies predefined assembly descriptor to create a general assembly of a binary package with all the dependency libraries included unpacked inside the archive.
<project>
[...]
<build>
[...]
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2-beta-5</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id> <!-- this is used for inheritance merges -->
<phase>package</phase> <!-- append to the packaging phase. -->
<goals>
<goal>single</goal> <!-- goals == mojos -->
</goals>
</execution>
</executions>
</plugin>
[...]
</plugins>
</build>
</project>
To create the project assembly, trigger the package phase:
mvn package
And this will produce the following assembly in the target directory:
target/child-1.0-SNAPSHOT-jar-with-dependencies.jar
I'm just not sure of what you want to do with this assembly (use it as dependency in portlet projects vs pull dependencies from the parent POM? ease the liferay deployment only?). All options are possible though.
Refer to the Maven Assembly plugin documentation for more details.
I finally was able to resolve it in the following way, I have not tested in the application server, but the resulting archive is a jar file with the content of all the desired dependencies.
Thanks Vincent for the tip :)

What is awesome about shade plugin is that it warns you when you are including classes that are overlapping (an example is the spring jar (the full one) with aopalliance classes)
