Ho una piccola applicazione java spring che sto cercando di compilare con maven ed eclipse keplero ma ottengo il seguente errore.


Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5


grazie a chi interviene
