Unable to find feature.xml in directory

I just added a plugin to my Eclipse RCP project and am getting the error: Unable to find feat开发者_运维百科ure.xml in directory

What does this mean?

You have probably installed the plugin incorrectly. The feature needs to be unpacked in order for it to work. What happens now is that Eclipse is looking for a feature.xml file but only finding the jar file. Check your .../eclipse/features catalaog and you will find jar'd features. Using a program and unzipping the jar file should solve the problem.

If you install using an update site the feature will be unpacked automatically.

The problem occurs if you install the plugin+feature not via update site.

check configuration/org.eclipse.equinox.simpleconfigurator/bundles.info to see whether your plugins has registered here.
