Description

http://maven.apache.org/plugins/maven-enforcer-plugin/rules/requirePluginVersions.html describes how to configure the plugin.

But by default it won't work, because you have to specify the version of the enforcer plugin itself.

If you pick 1.0-alpha-3, you get
[INFO] Failed to configure plugin parameters for: org.apache.maven.plugins:maven-enforcer-plugin:1.0-alpha-3
Cause: Class 'org.apache.maven.shared.enforcer.rule.api.EnforcerRule' cannot be instantiated

If you pick 1.0-alpha-4-SNAPSHOT (which would fail the rule anyway, but...), you get
[ERROR] FATAL ERROR
