/**
* Will merge the distributions of the current project into mergeIntoProject. For
* example, to bundle spring-test-mvc in spring-test's jars. This script will perform the
* following steps:
* <ul>
* <li>Ensure that jar tasks of the project being merged from will execute the tasks of
* the project being merged into</li>
* <li>Add the project being merged into to the classpath of the project being merged
* from</li>
* <li>Update the pom.xml of the project being merged into to contain the entries from
* the project being merged from</li>
* </ul>
*
* Example Usage:
*
* ext.mergeIntoProject = project(':spring-test')
* apply from: "${rootProject.projectDir}/merge-dist.gradle"
