stacey11,
Sorry that you are seeing this issue.
This is a known bug in M2E, which is the base for Maven4MyEclipse.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=394042
I have raised a PR for the dev team to look into it.
The error means that there is a Variable based classpath entry in the project. It should be removed.
You can either manually remove all classpath entries with kind=”var” in .classpath file or remove from Libraries tab in the Configure Build Path dialog.
Let us know how this works for you.
