--------------------------------------
Summary: copy-dependencies overwrites artifacts of the same
artifact id
Key: MDEP-776
URL: https://issues.apache.org/jira/browse/MDEP-776
Project: Maven Dependency Plugin
Issue Type: Bug
Components: copy-dependencies
Affects Versions: 3.2.0, 3.1.2
Reporter: Nikolaos Georgiou
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)
