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
JackDev's option 3 works for me after I changed the default repository to another folder.
Below is what I see after M2E plugin automatically download the maven-resources-plugin-2.6. Maybe this could give you some hint if you want to take the manual approach. The necessary files can be downloaded from here: https://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-resources-plugin/2.6/
