Joerg Schaible commented on MNG-4732:
-------------------------------------

I've been bitten by it: WebLogic comes with jars named like "foo+ssl.jar". Although you can deploy it with this artifactId, you cannot add it to your dependencies, since Maven complains about the invalid artifactId at dependency resolution. And it is no wonder, that it is not supported, since '+' decodes to space as part of a URL.

> If a / character is accidentally put into a version string it can cause some weird results.  Maven installs and deploys some nameless (.jar, -sources.jar, etc) files without an error messages.  This can be a bit tricky to track down, so it would be better if Maven did some validation on the version string to prevent the '/' character or other invalid characters.
