Technically, this is correct but doesn't really help to locate the root cause of the problem. If maven can't read the plugin.xml file of a plugin, it should abort with an error during the XML parsing step instead of trying to use the plugin anyway.

Real world case: The plugin is downloaded via a proxy and the download aborts before the full file is transferred or the proxy returns a HTML file ("A virus was detected blahblah") instead of the JAR. This can lead to corrupt JARs in the repository which leads to the error above.

PS: Not sure if this is "Plugin API" or "Plugins and Lifecycle". Please feel free to move the error report to the right place.

Thanks for the fix in 2.0.10. This one really cost me a lot of nerves

Pushing to 2.0.11 so we can have a smaller set of high-value issues to target for the next release (2.0.10).
