How to tell Maven to include the jar dependency, not the subproject source directory in Eclipse?

Question

I use Apache Maven to manage my Java libs (jar) and some of projects that use the libs. For convinience, I use mvn eclipse:eclipse to generate Eclipse project f

I believe this is actually because they're related projects in Eclipse. So if you right-click on your main project and go to Project References your lib project should be ticked.

If you run mvn eclipse:eclipse it will automatically add project references for any sub-projects (modules). You can change this with the useProjectReferences property of the maven eclipse plugin.

It defaults to true, but

When set to false, the plugin will not create sub-projects and instead reference those sub-projects using the installed package in the local repository

To use the property either set the property in your pom.xml

    
        
            org.apache.maven.plugins
            maven-eclipse-plugin
            2.9
            
                false
            
        
    

Or as a property on the command line:

mvn eclipse:eclipse -Declipse.useProjectReferences=false
