Symlinks are frequently unavailable on Windows (must be on NTFS and user must
have SeCreateSymbolicLinkPrivilege). Removing the symlinks for licenses/common/
should enable the build to function mostly normally on Windows. The individual
license files will be incorrect, but that shouldn't matter for local builds.
Release builds are done on *nix.
The plugin rolls several different plugin executions into one. The common files
are distributed using a resource jar, used by and unpacked by the plugin.
