Why am I getting a "<plugin name> does not exist or no valid version" error?
This means that Maven is unable to access the required plugin from your local repository, and unable to access the official or 'central' Maven2 plugin repository.
You may troubleshoot the problem by performing the following actions:
- If you are behind a http proxy, please check the Maven2 proxy settings guide.
- If the plugin you seek cannot be redistributed freely then you may add it manually to your repository.
If the problem still persists you may seek help from the Maven user list, browse archived discussions, or log a ticket describing your problem if you think you have found a bug. Tickets could also be issued for feature enhancement requests, and other tasks.
