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
My problem was the location of the config file.
In eclipse settings (Windows->preferences->maven->User Settings) the default config file for maven points to C:\users\*yourUser*\.m2\settings.xml
. If you unzip maven and install it in a folder of your choice the file will be inside *yourMavenInstallDir*/conf/
, thus probably not where eclipse thinks (mine was not). If this is the case maven won't load correctly. You just need to set the "User Settings" path to point to the right file.
