ManifestParser: Throw exception if remote does not have fetch attribute
In the repo manifest documentation [1] the fetch attribute is marked as "#REQUIRED". If the fetch attribute is not specified, this would previously result in NullPointerException. Throw a SAXException instead. [1] https://gerrit.googlesource.com/git-repo/+/master/docs/manifest-format.txt Change-Id: Ib8ed8cee6074fe6bf8f9ac6fc7a1664a547d2d49 Signed-off-by: Han-Wen Nienhuys <hanwen@google.com> Signed-off-by: David Pursehouse <david.pursehouse@gmail.com>
