Maven creates empty plugin metadata during offline mode, causing successive
online builds to fail
-------------------------------------------------------------------------------------------------
Key: MNG-3312
URL: http://jira.codehaus.org/browse/MNG-3312
Project: Maven 2
Issue Type: Bug
Components: Artifacts and Repositories
Affects Versions: 2.0.7
Reporter: Kohsuke Kawaguchi
Cd to any Maven project that's lying around, then do this:
{noformat}
rm -rf ~/.m2/repository/org/apache/maven/plugins/maven-clean-plugin
mvn -o clean
{noformat}
This fails, as expected, because the maven-clean-plugin doesn't exist locally.
Now try this:
{noformat}
mvn clean
{noformat}
Even though now Maven is online, it still fails with the same error. No
download is attempted (unless I add -U.)
This is because even in the offline mode, Maven creates
~/.m2/repository/org/apache/maven/plugins/maven-clean-plugin and put empty
repository metadata. This causes the later online Maven build to believe that
the repository was checked and no plugin was found there.
Maven shouldn't create an empty repository metadata in the local repository if
In the offline mode.
