        public static java.lang.String getVersionFromManifest​(java.lang.Class<?> clazz,
                                                      java.lang.String jarName,
                                                      java.lang.String defaultVersion)
        Attempt to figure out the version of a given library/jar from its MANIFEST.MF file. If nothing can be found, use the default value provided as a fallback. This first attempts to get the manifest file via a "fast path" using the jar of the provided class file. If that fails, we scan all manifests for the correct one based on the expected jar name.
        Parameters:
        clazz - a class to get the jar for
        jarName - the name of the jar file to do a "contains" match on
        defaultVersion - a default value to return if nothing is found in the manifest
        Returns:
        the version of the library based on the MANIFEST.MF file
