Hello, I am having some trouble making maven work as regular make and I believe I am missing something obvious.
I have a root project: say R and two subproject (modules): A & B. B depends on A. All versions in all the projects are specified with –SNAPSHOT. Now B is using some class from A. If I change that class in A, but don’t change anything in B and then run “mvn install” it will recompile A, but it won’t recompile B (because nothing changed there) and the repository ends up with version of B which uses obsolete version of this class from A. If I do “mvn clean install” it works, but it’s expensive to do it on a regular basis (at least on a big project). Basically I want to just invoke “mvn somegoal” on a root project so that it picks up all the changes and dependencies and rebuilds what needs to be rebuilt. In this case it should figure out that it needs to rebuild B as well because it's dependency changed. I believe it tries to rebuild B, but since nothing changed there it does not recompile it. I tried reactor plugin but it's essentially the same, it does not recompile B in this case. Thank you! -- Dmitry Skavish
