In my team we are migrating from svn to git and we have agreed upon embracing the git-flow flow. I've been playing around a while with SourceTree and the Git-Flow extension. Now, we have decided that the develop branch will be called development/current instead, but I do not find in the SourceTree UI where to change the Git-Flow configuration.
Is it possible, once initialized, to change the Git-Flow configuration for a given repository?
No, it is not possible (at least not at SourceTree 1.4.1.0).
It is possible however to do it manually by editing the file /.git/config in your git repository.
The Git-Flow extension adds it s configuration in the following two sections, which can be freely edited.
[gitflow "branch"]
master = master
develop = development/current
[gitflow "prefix"]
feature = feature/
release = release/
hotfix = hotfix/
versiontag = release/
support = support/
