I am using Eclipse Maven (m2e) inside Eclipse and I am running my project like this:
My pom.xml looks like this:

After I run the maven install it is working...
Maven run configurations:
The problem is that my generated .jar it doesn't have the dependencies included....
How can I configure pom.xml to include all my dependencies in .jar format and not unpacked.. because it seems that unpacked are not working correct...
To be sure that including all jars is ok.. I downloaded and added each library into jar's /lib folder and the jar is running... so.. my only question is: How can I configure pom.xml in order to add all my dependencies in jar format?
I tried all methods:
assembly:assembly
assembly:single
assembly:single with my descriptor (an assemble.xml file) but it wasn't working
maven copy dependencies plugin but still not working with Eclipse Maven - m2e
I am out of solutions... can anyone tell me a proper way to add my dependencies in jar? I can't believe that maven is so complex and I can't find an answer to my question everywhere..
Thank you in advance
There are a couple of ways of doing this.
1) If you want an uber-jar (repacked with all dependencies), look into using and configuring the maven-shade-plugin:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>1.6</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>com.group.id.Launcher1</mainClass>
</transformer>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
This will unpack all dependencies and merge them into one JAR file.
2) If you want to deliver a bundle (zip, tar.gz, etc) with the unpacked JAR files in the bundle (perhaps under lib/) then you need to look into the maven-assembly-plugin:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.3</version>
<executions>
<execution>
<id>create-distro</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<descriptors>
<descriptor>src/main/assembly/dist.xml</descriptor>
</descriptors>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
Note that this requires an assembly descriptor src/main/assembly/dist.xml and example looks like this:
<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0">
<id>distribution</id>
<formats>
<format>zip</format>
</formats>
<dependencySets>
<dependencySet>
<useProjectArtifact>false</useProjectArtifact>
<useTransitiveDependencies>false</useTransitiveDependencies>
<unpack>false</unpack>
<scope>runtime</scope>
<fileMode>0755</fileMode>
<directoryMode>0755</directoryMode>
<outputDirectory>bin</outputDirectory>
<includes>
<include>com.group.id:project-launch1</include>
<include>com.group.id:project-launch2</include>
</includes>
</dependencySet>
<dependencySet>
<useProjectArtifact>false</useProjectArtifact>
<useTransitiveDependencies>true</useTransitiveDependencies>
<unpack>false</unpack>
<scope>runtime</scope>
<fileMode>0644</fileMode>
<directoryMode>0755</directoryMode>
<outputDirectory>lib</outputDirectory>
<includes>
<include>com.group.id:project-lib1</include>
<include>com.group.id:project-lib2</include>
<include>com.group.id:project-lib3</include>
<include>com.group.id:project-lib4</include>
</includes>
</dependencySet>
</dependencySets>
</assembly>
And since you are now assembling dependencies, you have better define the dependency in the pom.xml, like so:
<dependencies>
<dependency>
<groupId>com.group.id</groupId>
<artifactId>project-launch1</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>jar</type>
</dependency>
<dependency>
<groupId>com.group.id</groupId>
<artifactId>project-launch2</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>jar</type>
</dependency>
<dependency>
<groupId>com.group.id</groupId>
<artifactId>project-lib1</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>jar</type>
</dependency>
... and so on ...
</dependencies>
3) If you are delivering a bundle with an executable JAR file launcher, you will likely need to add a maven-jar-plugin configuration in addition to the maven-assembly-plugin:
<dependencies>
<dependency>
<groupId>com.group.id</groupId>
<artifactId>project-lib1</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>jar</type>
</dependency>
<dependency>
<groupId>com.group.id</groupId>
<artifactId>project-lib2</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>jar</type>
</dependency>
<dependency>
<groupId>com.group.id</groupId>
<artifactId>project-lib3</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>jar</type>
</dependency>
... and so on ...
</dependencies>
<build>
<plugins>
<plugin>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<addMavenDescriptor>false</addMavenDescriptor>
<compress>true</compress>
<manifest>
<mainClass>com.group.id.Launcher1</mainClass>
<addClasspath>true</addClasspath>
<classpathPrefix>../lib/</classpathPrefix>
</manifest>
</archive>
</configuration>
</plugin>
</plugins>
</build>
Note that the "addClasspath" directive adds the project dependencies to the class path. This is needed for JAR launchers, as they explicitly ignore all CLASSPATH environmental variables.

I am using Intellij community edition v2020.3.2 and Java 8.
I am adding external jar file by following steps, File -> ProjectStructure -> Project Settings -> Modules -> + -> Jars or Directories.
Execution works fine in IDE. But when install using maven throws an error "package package-name does not exist".
My pom.xml looks like

When I remove the external jar, the maven install works fine.
To use local jar with Maven you will first need to install this jar into your Maven local repository. Then you can specify it as a dependency in your Maven pom.xml build file and IDE will also link it automatically based on the Maven configuration. You can import it using similar command:
mvn install:install-file \
-Dfile=<path-to-file> \
-DgroupId=<group-id> \
-DartifactId=<artifact-id> \
-Dversion=<version> \
-Dpackaging=<packaging> \
-DgeneratePom=true
See this answer:
Warning: never modify IDE project structure settings manually in Maven/Gradle based project - as IDE will reset this manual configuration after Maven/Gradle Reload.
Here is how I add the jars to the maven POM:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<version>2.5.2</version>
<executions>
<execution>
<id>FIRST_LIBRARY_ID</id>
<phase>initialize</phase>
<goals>
<goal>install-file</goal>
</goals>
<configuration>
<file>lib/my_lib_1.jar</file>
<groupId>com.group</groupId>
<artifactId>FIRST_LIBRARY_ID</artifactId>
<version>1.0</version>
<packaging>jar</packaging>
</configuration>
</execution>
<execution>
<id>SECOND_LIBRARY_ID</id>
<phase>initialize</phase>
<goals>
<goal>install-file</goal>
</goals>
<configuration>
<file>lib/my_lib_2.jar</file>
<groupId>com.group</groupId>
<artifactId>SECOND_LIBRARY_ID</artifactId>
<version>1.0</version>
<packaging>jar</packaging>
</configuration>
</execution>
</executions>
</plugin>
Then Just add them to dependencies:
<dependency>
<groupId>com.group</groupId>
<artifactId>FIRST_LIBRARY_ID</artifactId>
<version>1.0</version>
</dependency>
<dependency>
<groupId>com.group</groupId>
<artifactId>SECOND_LIBRARY_ID</artifactId>
<version>1.0</version>
</dependency>
You can put what you want in <id> tags, just every execution step must to have different ids.
The things happens into the <configuration> tag, insert your jar filename and the other values are custom, you only must to use the same <groupId> <artifactId> and <version> in the dependencies reference.
This is my pom file:

And when I run the jar I get:
Exception in thread "main" java.lang.NoClassDefFoundError: com/mxgraph/swing/mxGraphComponent
which is part of the jgraphx dependency.
What am I missing?
you can do it by adding this dependencySet to your assembly file descriptor
<dependencySet>
<outputDirectory>/</outputDirectory>
<unpack>true</unpack>
<scope>system</scope>
</dependencySet>
this assembly descriptor add all dependencies including system scoped
<assembly

Yes, and this is one of the reasons you shouldn't abuse system scope dependencies (which is globally a bad practice) and this problem has already been mentioned several times here on SO (here, here). I'm proposing a solution to deal with project relative dependencies in a "clean" way in this answer.
You should remove the <scope>system</scope> clauses from those dependencies.
When the scope is set to system that means the artifact is ALWAYS available, so jar-with-dependencies does not include it.
It must not be system scope in the first place. This is the source of your problem.
Install/deploy your dependency into the repository and make it a normal compile (or runtime) scope dependency.
There are 2 solutions:
Recommended: create a repository and then provide the dependency in the same way as you provide dependency from maven repository.
Though the above solution is the recommended one, but if you don't want to create the repository, then here is the workaround:
First in your pom.xml, remove the system scope and the systemPath. Please note that the commented lines were removed to resolve this issue.
<dependency>
<groupId>com.paymentus.timgroup.statsd</groupId>
<artifactId>paymentus-timgroup-statsd-client</artifactId>
<version>1.0-SNAPSHOT</version>
<!--<scope>system</scope>-->
<!--<systemPath>${basedir}/external_lib/xyz.jar</systemPath>-->
</dependency>
Use maven-install-plugin in the same pom.xml. You need to modify the details in bold, no need to change any other thing in this plugin:

Unpack your jar and add it to src/main/resources.
I'm trying to create a jar from my maven project containing the jar files from dependencies in a specific folder.
The framework I'm writing a plugin for requires external dependencies to be supplied as jar files in the plugin jar.
For example:
xxxx.jar
/myapp/myjavaclasses
/lib/externalDependencies.jar

In the above pom file we have the dependency
org.apache.httpcomponents
, this dependency contains the following jars
httpclient-4.5.8.jar
httpcore-4.4.11.jar
these jars need to be imported in my final jar under the folder /lib.

The Jar is created properly and the main class is mentioned in the manifest. I have the following questions :
The target folder contains the classes folder whch has the class files. The jar also contains them so why are they needed. My goal is to have a executable jar with all the dependancies only.
The resources are not getting added in the jar at all. I have added the transformer according to instructions seen on the net but no use!!!
What are the other dir getting created in the target folder (maven-archiver, surefire, surefire-reports etc) ??
Another jar gets created every time i do a maven clean install (original-Listener....jar)
I have absolutely no clue about how to include resources. Any help is appreciated!!
EDIT:::
This is the tag i used for the maven-assembly-plugin:

This created the Listener-1.0-SNAPSHOT-jar-with-dependencies.jar with all the classes from referred jars in the folders. The manifest also contains the main class.
The problem still is that I cant include the resource bundle in the folder \src\main\resources.
Also I cant understand why jar files referenced from my code are included in the jar as well as inside the META-INF folder.
The problem wasn't in your maven-shade-plugin's configuration, rather that you have explicitly set resource directory to a wrong path:
<!-- wrong -->
<resource>
<directory>resources</directory>
</resource>
As <directory> element's doc says: "Describe the directory where the resources are stored. The path is
relative to the POM."
So if you follow default maven project structure you have to set like this:
<!-- correct -->
<directory>src/main/resources</directory>
or don't set it, then it falls back to same as maven defaults.
I removed the following from the pom.xml and the property files were included at the root dir.
<sourceDirectory>src/main/java</sourceDirectory>
<resources>
<resource>
<directory>resources</directory>
</resource>
</resources>
<testSourceDirectory>src/test/java</testSourceDirectory>
Still havent figured out why there is a repetition of the referred classes in the jar.
