How to resolve the errors after running "mvn compile" on guava-libraries project?

Question

I checked out guava-libraries and tried to build it with "mvn compile".

A mysterious error popped out and I failed to find a solution. But "mvn package" or "mvn install" succeeded without any errors.

Is 'compile' not a valid maven lifecycle for guava-libraries?

The core error message is below for your reference. Thanks for any help in advance.

[INFO] Unpacking /home/xxx/guava-libraries/guava/target/classes to /home/xxx/guava-libraries/guava-gwt/target/guava-sources with includes "" and excludes "META-INF/MANIFEST.MF"

Note: the paths in the error message are correct.

You ran into the bug MDEP-98 of the maven-dependency-plugin, which is executed during the build of guava-gwt. Unfortunately, there is no solution to work around this bug, except not using mvn compile but mvn package or mvn install instead.
