This is an interesting situation and certainly feels like a bug. I'd
say that Maven should *not* write the metadata file unless it actually
downloaded the plugin or successfully used it.
Has this been filed in JIRA, Wendy?

I can reproduce this by deleting the metadata for maven-clean-plugin
and then running:
$ mvn clean -o
This will will write a metadata file containing only
<?xml version="1.0" encoding="UTF-8" ?>
<metadata>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-clean-plugin</artifactId>
</metadata>
Subsequent executions of "mvn clean" will fail with 'no valid version'
until you either delete the metadata file *or* run with -U on the
command line to force an update.
