Current master is now at https://github.com/codehaus-plexus/plexus-classworlds
This project maintains a legacy compatibility layer in the org.codehaus.classworlds package.
This package cannot be removed without coordinating with the Eclipse Sisu and Apache Maven teams.
The compiled bytecode of org.eclipse.sisu:org.eclipse.sisu.plexus directly references
org.codehaus.classworlds.ClassRealm, ClassRealmAdapter, and ClassRealmReverseAdapter.
Removing this package causes ClassNotFoundException at runtime for any application using Sisu
(which includes all Maven 3+ builds).
PR #141 removed this package and had to be reverted immediately (see commit 223416e).
New code should use the org.codehaus.plexus.classworlds package.
See COMPATIBILITY.md for the full picture, including what Sisu references
and what is required before any future removal can be considered.
