title: Include Gradle module to Maven project
body: <p>We have large project that uses Maven as a build system. We decided that in future projects we will use Gradle as more convenient tool, but we want to use Gradle for our legacy project too.</p>
  
  <p>I think that migrating from Maven to Gradle at one time will be very painful, because we have TONS of code in POM files (we have really heavy build logic).</p>
  
  <p>I know, that Gradle have automigration tool (gradle init) but it doesn't work properly (I think this tool is for small Maven projects with no specific build logic).</p>
  
  <p>So, here is a question: can I <strong>include Gradle module to Maven project</strong> to migrate with small steps? Maybe there is Maven plugin, that allows to treat <code>build.gradle</code> as <code>pom.xml</code> file?</p>
