[Plugins] Not a valid object name FETCH_HEAD when running update-release-info #120116
Description
After following the instructions listed in the plugin readme
I have the tool fail with the following stack trace.
To reproduce you can clone a fresh copy of the plugins repo or you can run rm .git/FETCH_HEAD from the root directory of plugins.
The issue is that FETCH_HEAD is not guaranteed to be present in all git directories. It is a temporary file.
Workaround for this issue is to run git fetch.
dart run ./script/tool/bin/flutter_plugin_tools.dart update-release-info --version=minimal --changelog="SOME TEXT."
Unhandled exception:
ProcessException: fatal: Not a valid object name FETCH_HEAD
Command: git merge-base FETCH_HEAD HEAD
