you have a very old snapshot of the plugin plugin. 2.2 has been
released.
Also, builds should not even be attempting to get snapshots from
http://repository.codehaus.org.

Hi,
I've tried building some mojo plugins that depend on root mojo POM
version 13 and they failed with 2.0.5. In particular the exec plugin
until I partially cleaned my repository.
maven 2.0.4 was ignoring the maven-plugin-plugin because it is
incompatible with 2.0.5:
[INFO] Ignoring available plugin update: 2.2-SNAPSHOT as it requires
Maven version 2.0.5-SNAPSHOT
But with 2.0.5 it tries to use it but did not find it:
[WARNING] Unable to get resource
'org.apache.maven.plugins:maven-plugin-plugin:pom:2.2-SNAPSHOT' from
repository snapshots (http://snapshots.repository.codehaus.org)

Try downloading the file manually from the project website.
Then, install it using the command:
mvn install:install-file -DgroupId=org.apache.maven.plugins
-DartifactId=maven-plugin-plugin \
-Dversion=2.2-SNAPSHOT -Dpackaging=maven-plugin -Dfile=/path/
to/file
Cleaning up my repository fixed it.

Is cleaning up the repository an expected thing to do ?
Cheers,
