Find jars containing class file in Maven project

As far as I know, there is no dedicated Maven plugin (3.0+) that will look for dependencies for class declarations. However, I believe I understand your needs and suggest the following solutions:

Find duplicate ads

mvn dependency:analyze-duplicate -DcheckDuplicateClasses

      

        
        
        
      

    

Find containing JAR in Eclipse

Use CTRL+ SHIFT+ Tto bring up the Open Type dialog . Entering part or full name of a class is a list of containing JAR files in the assembly classpath.

Find containing JAR without IDE

If you need more programmatic control to check on systems without an IDE, such as a CI server, you can use the following snippets to view JAR files that contain a specific class or even a specific name pattern. This approach uses the Maven Dependency Plugin to collect all dependencies in a temporary directory so that they can be easily found.

For Unix systems or Git Bash

mvn clean dependency:copy-dependencies -DoutputDirectory=target/temp
for j in target/temp/*.jar; do jar -tf $j | grep SomeClass && echo $j; done

      

        
        
        
      

    

For Windows through the shell cmd

mvn clean dependency:copy-dependencies -DoutputDirectory=target/temp
for /R %G in (target\temp\*.jar) do @jar -tf "%G" | find "SomeClass" && echo %G

      

        
        
        
      

    

In either case, the corresponding complete package entry and class name will be displayed, followed by the name of the JAR file containing. The search parameters grep

and find

can be further refined to restrict matches as needed, for example SomeClass.class

.

Hope this helps.
