Eclipse2 IDE for development and integration for ROS2 Foxy

edit

I have solved the problem in following manner:

1. In webpage https://index.ros.org/doc/ros2/Tutori...: Replace ament command with colcon. Create a new Builder for the project with colcon command. set location as /usr/bin/colcon. Set appropriate arguments which you will use to compile the package from the terminal.

   1. For indexer: In C/C++ General -> Path and Symbols -> tab includes -> for GNU C++ language: Add path of ROS includes (/opt/ros/foxy/include), Add path of includes of specific libraries which pkg uses, Add install path of the other ros-packages from the underlay/current workspace environment.
