ROS_PACKAGE_PATH erased every time I source devel/setup.bash

edit

Hello,

I need your help on what appears like a bug in catkin. I have two workspaces

• catkin_ws1 contains :
  • pkg1
  • pkg2
• catkin_ws2 contains :
  • pkgA
  • pkgB

If I source the setup of catkin_ws1 and echo ROS_PACKAGE_PATH everything works as expected

cd ~/catkin_ws1
source deve/setup.bash
echo $ROS_PACKAGE_PATH
~/catkin_ws1/src/pkg1:~/catkin_ws1/src/pkg2:/opt/ros/kinetic/share

When I source the setup of the second workspace catkin_ws2 the old ROS_PACKAGE_PATH is erased

cd ~/catkin_ws2
source deve/setup.bash
echo $ROS_PACKAGE_PATH
~/catkin_ws1/src/pkgA:~/catkin_ws1/src/pkgB:/opt/ros/kinetic/share

I lose the ~/catkin_ws1/src/pkg1:~/catkin_ws1/src/pkg2

Is there a problem in my configuration or is it an issue related to catkin ?

Config

• catkin_tools 0.4.4
• Python 2.7.12
• GCC 5.4.0
• ros kinetic

Cheers,
