// sbt doesn't automatically load the content of the MANIFST.MF file, therefore

// MANIFEST.MF is `x.y.z.qualifier` but we need to replace the `qualifier` part
// with a unique identifier otherwise OSGi can't find out which nightly build
// is newest and therefore not all caches are updated with the correct version
// of a nightly.
