Duplicate classes on classpath

[slawekjaranowski]

I use in my maven project this library in version 1.1.0

Last time I have discovered that on my plugin classpath I see duplicate some classes eg.
org.codehaus.plexus.DefaultPlexusContainer

This class is in two artifacts:

• org.codehaus.plexus:plexus-container-default:1.0-alpha-9-stable-1 - required by plexus-resources
• org.eclipse.sisu:org.eclipse.sisu.plexus:0.3.3- required by maven-core and maven-plugin-api

I don't see any problems during plugins works, maybe something is doing by maven-core with plugin classpath.

Please exclude org.codehaus.plexus:plexus-container-default that component is no longer maintained and sisu is its replacement.

[slawekjaranowski]

As I see plexus-resources is used in many places: https://mvnrepository.com/artifact/org.codehaus.plexus/plexus-resources/usages
so everybody today should exclude this ... the better way is refresh dependency of this component and release new version.

If you interested I can do it.

Yes, let's try to see how it will look like.
Some time ago I was trying do do something similar: https://github.com/codehaus-plexus/plexus-containers/pull/16/files
