[MRESOURCES-278] Regression - Changed copy behaviour if file already exists

**[Georg Tsakumagos](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=JIRAUSER282043)** opened **[MRESOURCES-278](https://issues.apache.org/jira/browse/MRESOURCES-278?redirect=false)** and commented

With MSHARED-966 the behavior for the maven-resources-plugin changed dramatically.

Now an exception is thown if a file already exists.
Before it was only overwritten if newer and no exception was thrown.

The new behavior breaks many builds. If this new behavior is a feature the plugin site should be updated with a big (!) warning to everyone.
