> The _<overwriteIfNever/>_ property does not work for classifier _<classifier>sources</classifier>_ . As soon as the overWriteIfNever property is enabled, the artifacts with classifier "sources" are always overwritten. So not needed files are written very often to the disk. 
> The flag seems to work as expected for executions where no classifier is specified. 
> See the attached sample project where execution "thirdparty" can handle overwriteIfNever correctly. While the execution "thirdparty.sources" always copies files to the disk:

> The not yet released version 2.9 in use was: maven-dependency-plugin-2.9-20140907.174645-631
