Description

maven-help-plugin:2.1.1:describe with maven 3.0.1 doesn't show the parameter Required and Expression status which is essential to run the goal.

The patch:

• fixed the missing Expression
• display Required=true based on the flag status

After applied the patch run following command to test:
mvn org.apache.maven.plugins:maven-help-plugin:2.2-SNAPSHOT:describe -Ddetail -Dplugin=eclipse -Dgoal=configure-workspace

You will expect to see:
workspace
Required: true
Expression: ${eclipse.workspace}
Directory location of the Eclipse workspace.

Without patch, you will see:
workspace
Directory location of the Eclipse workspace.
