I have 3 maven projects
When i build each of the projects i have to go into eac
You're looking for Maven aggregation without inheritance. As shown in the referenced page, you just create a new POM whose packaging is "pom" and which has a list of "modules". A module is a relative path to another Maven project:
...
pom
...
foo
../bar
../../../other-projects/baz
Default behavior when building such a pom--known as an "aggregator"--is to build all of the modules as if you'd executed Maven in each module directory with the same arguments.
