Maven resolver issues

[ethauvin]

compile("net.sf.jtidy:jtidy:")

Fails to resolve, probably because the latest version number is r938, not really a semantic version.

Additionally, I have a pom in my local maven repo that was generated by Gradle, with the following dependencies:

Kobalt is unable to resolve the dependencies that have a + in the version.
