如何将现有的Maven项目作为模块添加到另一个Maven项目？

Question

I have a maven project which needs to be a module for another maven project. Is there a way to achieve this in eclipse or from the cli? I added the

 <module>existing_maven_proj</module> 

in the POM of the parent project and ran maven install but this doesn't seem to add the module

Answer 1

If you use M2e with Eclipse you do not need to do that, because Eclipse resolves dependencies across the workspace. You just need to have the two projects open and your dependencies declared correctly.

Answer 2

If I understand you correctly, you want to update the internal Eclipse configuration for the updated maven project structure. Run

mvn eclipse:eclipse

in you maven top level module. You might also need to import the new maven module. Just do a regular "Import existing maven project into workspace" to get this done.
