title: Appending to .classpath during `grails test-app -unit`
body: <p>I have a unit test that I want to run, but I want to reference a class in another project within the workspace during the tests.  I successfully added the project to the Build Path within Eclipse, but when I Run As - grails test-app -unit I get the error that says <code>unable to resolve class com.example.domain.Phone</code> during compile time.</p>
