How to compile dependency in maven?

Question

Scenario:

I have a main level project A and within A , two child projects B and C worked on by different developers , but they agree on the abstraction through comm

Answer 1

If you want to build B and automatically build it's dependencies you can use the advanced options of the maven reactor like –-also-make-dependents .

mvn clean install –-projects B –-also-make 

Or short

mvn clean install -pl B -am

That will compile all submodules of A whose B depends on . There are a useful post on sonatype blog on the advanced options of maven reactor. http://www.sonatype.com/people/2009/10/maven-tips-and-tricks-advanced-reactor-options/
