Repositories might not have branches for each an every ROS version. Sometimes the same code is being used for different ROS distributions and then only a single branch (commonly with the name of the older ROS distro) exists.
You can find the information you are looking for by look into the rosdistro database. In the Indigo distribution file you will find an entry for rqt
which specifies the URL and branch name to be used in that ROS distro: https://github.com/ros/rosdistro/blob...
So the branch you are looking for is groovy-devel
:
rqt:
doc:
type: git
url: https://github.com/ros-visualization/rqt.git
version: groovy-devel
release:
packages:
- rqt
- rqt_gui
- rqt_gui_cpp
- rqt_gui_py
- rqt_py_common
tags:
release: release/indigo/{package}/{version}
url: https://github.com/ros-gbp/rqt-release.git
version: 0.4.8-0
source:
type: git
url: https://github.com/ros-visualization/rqt.git
version: groovy-devel
status: maintained
As an alternative you could also use rosinstall_generator
to fetch the information for you:
rosinstall_generator --rosdistro indigo rqt --upstream-development
- git:
local-name: rqt
uri: https://github.com/ros-visualization/rqt.git
version: groovy-devel
