I can see lot of compilation issues after setting up my development environment using "mvn eclipse:eclipse". All these compilation issues are resolved after adding "target/generated-test-sources" as a source folder to the common project.
When verified the "pom.xml", it's noticed that these are included under "generate-test-sources" phase. This seems to be a problem occurred because of incorrect understanding/usage of "build-helper-maven-plugin" in Common project.
All these compilation issues are resolved after changing the phase to "generate-sources".
I found similar issue here.
