The dependency-versions-check plugin verifies that all resolved versions of artifacts are at least the versions specified by the project dependencies. The Maven dependency resolution process will substitute versions for the different artifacts in a dependency tree and sometimes chooses incompatible versions which leads to difficult to detect problems. This plugin resolves all dependencies and collects any requested version. It evaluates whether the resolved versions are compatible to the requested versions and reports possible conflicts.
