The Maven License Verifier Plugin is a Maven plugin that is intended to check the licenses of artifacts managed by Maven. This can be done during the build process, you can choose to let the build fail if an artifact with a wrong license is used. The licenses are categorized by a definition file that lists them with their different URLs and names. This can be different from project to project.
The Subversion Authentication Parser Module is a Java library that can read a Subversion svnaccess file and convert it into an object tree that can be used to grant permission to different parts. Furthermore, you can define an object tree that represents permission for locations in repositories and/or trees. This gives you the possibility to use this module within your application either to read the Subversion svnaccess file or use it as a separate permission system.
