What does the exported
attribute do in this .classpath line?
<classpathentry exported="true" kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER"/>
I've got a project that builds & runs fine with and without it. So, what difference does it make?
Apparently in my particular case (a project I inherited) it isn't critical to have it. When is it critical to have this attribute added?
