copy-dependencies overwrites artifacts of the same artifact id

We have a project which has 2 dependencies of different groupId but same artifactId and version, e.g. com.acme:foo:1.2.3 and com.ecorp:foo:1.2.3

We use the copy-dependencies goal of the plugin to copy libraries under target/lib folder.

Actual Result:

• only one foo.jar survives in the target/lib folder. The other one silently gets overwritten. This leads to difficult to diagnose runtime errors, as one JAR is missing.

Expected Result:

• it should at least give a warning, if not an error, that it has overwritten an artifact during this process

Known workaround:

• we activated useRepositoryLayout, which allows both artifacts to survive under a directory structure, which complicates a bit our classpath building process (from target/lib/* we need to find all the JARs with a bit of bash glue)
