 2 | ================
 3 | 
 4 | If you use [bloom](http://wiki.ros.org/bloom) to release catkin packages into a rosdistro other than the public
 5 | one, you've probably come across a situation
 6 | [like this one](http://answers.ros.org/question/135976/bloom-could-not-resolve-rosdep-key-message_runtime/),
 7 | where the package you want to build depends on a package in the public rosdistro, and bloom doesn't know how to
 8 | resolve the rosdep key, since you've changed `ROSDISTRO_INDEX_URL`.
 9 | 
10 | Enter *rosdep-generator*, which parses the rosdistro file, and dumps a rosdep-formatted yaml into the current
11 | directory:
12 | 
13 | ```
14 | $ ./rosdep-generator --distro indigo
15 | Downloading: https://github.com/ros/rosdistro/raw/master/indigo/distribution.yaml
16 | Parsing 250264 bytes of yaml.
17 | Extracting package names.
18 | Assembling output yaml structure.
19 | Outputting: ros-rosdistro-indigo.yaml
20 | Complete. Suggested next steps:
21 | 
22 |     sudo sh -c 'echo "yaml file:///Users/mikepurvis/rosdep-generator/ros-rosdistro-indigo.yaml indigo" > /etc/ros/rosdep/sources.list.d/90-ros-rosdistro-indigo.list'
23 |     rosdep update
24 | ```
25 | 
26 | Execute the next steps to make rosdep aware of the public packages, then run:
27 | 
28 | ```
29 | $ export ROSDISTRO_INDEX_URL=https://github.com/me/my-secret-rosdistro/raw/master/index.yaml
30 | $ bloom-release -r indigo -t indigo my_secrete_package
31 | ```
32 | 
33 | Bloom will find your dependencies now.
