Recent eisop-plume-lib updates, e.g.
eisop-plume-lib/require-javadoc@2f3eaa1 , start using the new Gradle CF plugin, which has a new way to use a locally built CF.

Need to land eisop-plume-lib/plume-util#204 to upgrade the plugin in that project.
If I remember correctly, that project fails with the released version, but passes with master.
I need to review this.
