How to execute newly developed maven plugin in the same project

Question

I have a maven project with a couple of child modules. One is a new maven plugin. Another one is a test module where I want to run my newly developed plugin to ensure that it works fine.

In the test module I do a normal reference to my plugin: build > plugins > plugin > <definition of my plugin>. And then if I executed mvn clean test it works fine. The plugin is being compiled and later, in the next module it is executed.

But there are a couple of problems with this setup:

1. When I do mvn clean execution fails with plugin cannot be resolved as the second module does not have even compiled version of the plugin.

2. In IDE (Intellij IDEA) reimport of maven modules fails with the same problem.

I do not want to do mvn install to have it locally so the dependencies are resolved as I do changes quite frequently and do not want to reinstall it every time.

I do not want to write integration tests instead of running the plugin directly as I want a realistic test and moreover, the plugin setup is quite tricky and would be hard to replicate that in a test.

I thought that I could use systemPath to reference the plugin but I am not sure if that will work and how to set it up.
