I switched to a SNAPSHOT version of a plugin I use, and declared the corresponding snapshot repository in the POM like this:
<project> <!-- ... --> <build> <pluginManagement> <plugins> <plugin> <groupId>org.apache.openjpa</groupId> <artifactId>openjpa-maven-plugin</artifactId> <version>2.3.0-SNAPSHOT</version> </plugin> </plugins> </pluginManagement> </build> <repositories> <repository> <id>apache.snapshots</id> <name>Apache Snapshot Repository</name> <url>http://repository.apache.org/snapshots</url> <releases> <enabled>false</enabled> </releases> </repository> </repositories> </project> Now Maven keeps complaining about not being able to download the plugin from our corporate repository (which does not mirror anything on the internet) - it just ignores the repository defined in the POM.
