Description Michael Nosthoff 2018-06-05 15:27:08 UTC 
Hi,

since the latest rework in the git downloader component setting the version to the 'master' branch is not working anymore. 

The error I see:

  Could not fetch special ref 'master'; assuming it is not special.
  Commit 'master' does not exist in this repository

using another branch is working fine. If I use another branch first and then change the package to master it is switching the branch just fine and builds.



I tried some analysis:

When I use the command from [1] I get:

> git fetch origin master:master
fatal: Refusing to fetch into current branch refs/heads/master of non-bare repository
fatal: The remote end hung up unexpectedly

>git rev-parse --verify "master^{commit}"
fatal: Needed a single revision

So there seems to be a clash between the local master and the remote master in this case.
As said before, all this works when I first start the repo creation with another branch and then switch to master.

Regards,
Michael

As stated in the manual, Buildroot does not support it: "Do not use a branch name as version; it does not work"

If some uses of branch do work it's only by change. It can stop work at any new release.
