org.apache.maven.plugin.PluginResolutionException: Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Faile
Hopefully I'm not late for the party.
Encountered this using Eclipse Kepler and Maven 3.1.
The solution is to use a JDK and not a JRE for your Eclipse project. Make sure to try maven clean and test from eclipse just to download missing jars.
