It only cleans the project. Show activity on this post. Show activity on this post. With the help of Purging local repository dependencies you need to do that.
Open the pom file and click on dependency Hierarchy. Select the the jar you want to delete. Right click and click on Exclude Maven Artifact.
The Maven Dependency Plugin will help, especially the dependency:analyze
goal:
dependency:analyze
analyzes the dependencies of this project and determines which are: used and declared; used and undeclared; unused and declared.
Another thing that might help to do some cleanup is the Dependency Convergence report from the Maven Project Info Reports Plugin.
You can use dependency:analyze -DignoreNonCompile
This will print a list of used undeclared and unused declared dependencies (while ignoring runtime
/provided
/test
/system
scopes for unused dependency analysis.)
## Be careful while using this, some libraries used at runtime
are considered unused

As others have said, you can use the dependency:analyze goal to find which dependencies are used and declared, used and undeclared, or unused and declared. You may also find dependency:analyze-dep-mgt useful to look for mismatches in your dependencyManagement section.
You can simply remove unwanted direct dependencies from your POM, but if they are introduced by third-party jars, you can use the <exclusions>
tags in a dependency to exclude the third-party jars (see the section titled Dependency Exclusions for details and some discussion). Here is an example excluding commons-logging from the Spring dependency:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
<version>2.5.5</version>
<exclusions>
<exclusion>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
</exclusion>
</exclusions>
</dependency>
Have you looked at the Maven Dependency Plugin ? That won't remove stuff for you but has tools to allow you to do the analysis yourself. I'm thinking particularly of
mvn dependency:tree
I had similar kind of problem and decided to write a script that removes dependencies for me. Using that I got over half of the dependencies away rather easily.
