We are pleased to announce the Maven Plugin Plugin 1.2 release! 

http://maven.apache.org/maven-1.x/plugins/plugin/

Maven Plugin management plugin. 

===============================================================================

Changes in this version include:

  New Features:

o Added assert:assertEquals tag to verify if two values are equal while 
  testing a plugin. 
o Added assert:assertFileExists tag to verify if a file exists while testing 
  a plugin. 
o Add plugin:test goal 
o Add plugin:repository-deploy goal 

  Changes:

o Fixed the plugin:download goal to work. Previously it would delete the 
  plugin you just downloaded. Also now leverages the plugin:uninstall goal. 
o Split plugin:download goal into plugin:download-artifact goal and the 
  original goal that downloads and installs the plugin. Download to local 
  repository as well.  

===============================================================================
