I copied some code from github and I have a problem with libraries. My code looks like:
When i click on Authentication to add a maven dependency
it shows that there is no results
What I do wrong? Should I install anything before clicking "add maven dependency" ?
Add
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-core</artifactId>
<version>5.4.0</version>
</dependency>
To your pom.xml
Or just search for another dependency. https://mvnrepository.com/
You need to add maven dependency in pom file:
https://mvnrepository.com/artifact/org.springframework.security/spring-security-core
My osgi bundle in servicemix need com.sun.javadoc for start.
I find dependency in maven repository but without success : the dependency in this link [here]
I try :
<dependency>
<groupId>javadoc</groupId>
<artifactId>javadoc</artifactId>
<version>1.3</version>
</dependency>
and
<dependency>
<groupId>com.sun</groupId>
<artifactId>tools</artifactId>
<version>1.7</version>
<scope>system</scope>
<systemPath>${java.home}/../lib/tools.jar</systemPath>
</dependency>
... without success.
So, I look for maven dependency for com.sun.javadoc with version : 1.7.0
thx
I resolved the problem :
In my pom.xml I make :
<dependency>
<groupId>com.sun</groupId>
<artifactId>tools</artifactId>
<version>1.7</version>
<scope>system</scope>
<systemPath>My_JAVA_HOME/lib/tools.jar</systemPath>
</dependency>
and in <Embed-Dependency> section I take the artifactId for this dependency, in my case it's "tools"
new mvn install and now in servicemix not stack for com.sun.javadoc
Just add tools.jar to your library folder.
example if you are using IntelliJ IDEA:
file->project structure->Libraries->(+) new project library->
Choose tools from your JDK path ->
your problem must be resolved
I have maven project. Maven build complete SUCCESS. But i can't make this project.
[INFO] BUILD SUCCESS
Project contains one module. Idea can't see dependencies.

Could you help me? Unfortunately, I can't add screenshots..
There are screenshots:

Project settings - Libraries - empty;
reimport didn't help;
Do the following steps:
Find your pom.xml in your files
Right click on it --> Maven --> Import
Wait for the project to load :D
Press ctrl+alt+shift+s (This opens the Projects window.)
Go to libraries and see if they are empty (they shouldnt)
If they are post your full pom.xml please so I can see the problem
If you still have a problem got to File --> Invalidate Caches
/Restart
Go to maven and Reimport All Maven Projects
Option Maven -> Reimport
should force Intellij to reload all dependencies. Alternatively, as mentioned in comments you can click the Reimport All Maven Projects button in Maven Projects view.
In my case, I had my own apache-maven-3.5.2 folder and a misconfiguration created my problem. Maybe it's your case too:
In rush, I set the local repository to C:/my/folder/apache-maven-3.5.2/settings.xml, but it must be a folder so Maven didn't allow me to download the dependencies. Then I changed the default (in the picture) and it worked.
Open the module dependencies (press F12 on the module), go to Modules -> Dependencies and make sure maven imports are part of the of this.
Try to import the project from sources, if this answer didn't help you.
The following worked for me.
Deleted the maven dependency from my local repository
mvn clean install downloaded the dependency again
File --> Invalidate Caches/Restart
I still saw the compilation error
on my mac, I hit option + enter, intellij asked me to add the jar to classpath
build -> make project
I had faced the same problem, and the issue was small. I had changed the location of settings.xml file of maven and Intellij was picking up the default from C:\users\.m2\settings.xml
So point your maven settings.xml to the correct file as below:
File--> Settings--> Build, Execution, Deployment--> Maven
then on the right window, override "User settings file" to the settings.xml where you have in your local disk.
If you have installed maven in a non-default location then this file you can find in:
\apache-maven-3.2.3\conf\settings.xml
Right click on pom.xml and click Add as Maven Project
I just tried to update my JFreeChart in Maven from:
<dependency>
<groupId>jfreechart</groupId>
<artifactId>jfreechart</artifactId>
<version>1.0.0</version>
</dependency>
to
<dependency>
<groupId>org.jfree</groupId>
<artifactId>jfreechart</artifactId>
<version>1.0.15</version>
</dependency>
On Maven Project Update - it says it can't find the artifact.
SO I TRIED TO GO BACK by editting the POM again to the old dependency.
Now on Maven Update it still says it can't find 1.0.15 artifact!!!!
In BuildPath>Libraries>Maven Dependencies jFreeChart1.0.15 is still should BUT all buttons are disabled so I can't remove it.
Right click on your project, then click on Maven->Update Project. Should help.
Try to configure your maven plugin to use maven central repository.

try {
JobExecution execution = jobLauncher.run(job, new JobParameters());
System.out.println("Exit Status : " + execution.getStatus());
} catch (Exception e) {
e.printStackTrace();
}
}
}
I am getting an error in import statements in my App.java classnd this is the message:
"The import org.springframework cannot be resolved."
I clearly mentioned the dependencies in POM.xml, but my java class still cannot pick the dependency from there.
You need to follow a few steps to debug properly.
1) mvn clean dependency:tree Take a look at the output to see exactly what you get and verify your dependencies are all there.
2) mvn clean compile. Does this fail? If not does that mean you only get the error in Eclipse?
You mentioned in a comment "And I run both commands above but I am getting this error". Did mvn clean compile work? Or did you get an error for that as well? If it worked then it's just an IDE problem and I'd look at the m2eclipse plugin. Better still, use IntelliJ as the free version has better maven support than Eclipse ;-)
Some style things ...
People often add too many dependencies in their pom file when they don't need to. If you take a look at a couple of links in mavenrepository.com you can see that spring-oxm and spring-jdbc both depend on spring-core so you don't need to add that explicitly (for example). mvn clean dependency:tree will show you what is coming in after all of that, but this is more tidying.
spring-batch-test should be test scope.
Finally my issue got resolved. I was importing the project as "Existing project into workspace". This was completely wrong. After that I selected "Existing Maven project" and after that some few hiccups and all errors were removed. In this process I got to learn so many things in Maven which are important for a new comer in Maven project.
The solution that worked for me was to right click on the project --> Maven --> Update Project then click OK.
Add these dependencies
</dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>
</dependencies>
My direct solution for this issue :
right click the project --> Maven ---> Add Dependency == then choose the name or parent name of missing dependency
In my case I had to delete the jars inside .m2/repository and then did a Maven->Update Maven Project
Looks like the jars were corrupt and deleting and downloading the fresh jar fixed the issue.
Right click project name in Eclipse, -->Maven-->Select Maven Profiles...
Then tick the maven profile you want to set. After click OK, Eclipse will automatically import the maven setting to your project. If you check your project's Property, you will find Maven Dependencies Library has been added.
Add the following JPA dependency.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
This answer from here helped me:
You should take a look at the build path of your project to check whether the referenced libraries are still there. So right-click on your project, then "Properties -> Java Build Path -> Libraries" and check whether you still have the spring library JARs in the place that is mentioned there. If not, just re-add them to your classpath within this dialog.

For me, this problem occured when I forgot to add spring web dependency. I checked it from eclipse's autocomplete that there are no org.springframework.web available for my project. Then from project > spring > add starters I added web dependency to the pom.xml.
if you're sure that your pom.xml is pretty good, then you have just to update the poject. right click on the project - Maven - update project. or simply alt+F5.
org.springframework.beans.factory.support.beannamegenerator , was my error. I did a maven clean, maven build etc., which was not useful and I found that my .m2 folder is not present in my eclipse installation folder. I found the .m2 folder out side of the eclipse folder which I pasted in the eclipse folder and then in eclipse I happened to do this :-
Open configure build path
maven
Java EE integration
Select Maven archiver generates files under the build directory
apply and close
My project is up and running now.
I imported a project as 'Existing Maven Project' and was getting this issue.
Resolution:
Changed Java Build Path of JRE System Library to Workspace defailt JRE [jdk 1.8]
Steps:
Right click on project -> build path -> configure build path -> Libraries Tab -> double click JRE System Library -> change to Workspace defailt JRE [jdk 1.8]
The only solution worked for me is add maven-compiler-plugin to the pom.xml
<project ...>
...
<build>
...
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
<fork>true</fork>
<executable>C:\Program Files\Java\jdk1.7.0_79\bin\javac</executable>
</configuration>
</plugin>
</plugins>
</build>
...
</project>
Had the same problem in Eclipse STS.
Changing the scope in the pom from "provided" to "compile" fixed the problem and when I changed it back everything was still OK.
There are few steps you can follow
remove repository folder
C:/Users/user_name/.m2
Then run command using IDE terminal or open cmd in your project folder
mvn clean install
Restart your ide
If not solve your problem then run this command
mvn idea:idea
right click project then maven then in textbox write pom.xml
When I imported the project in IntelliJ I got this issue. But it got resolved when I created the Project in IntelliJ -> File -> New -> Project -> Spring Initializr. Added dependencies in that window itself.
In my case, this issue was resolved by updating maven's dependencies:
In my case I used the below pom.xml file
here
and it worked for me.
