[ahmadnav]

Can be resolved by modifying ros2_dashing/ros2-linux/share/test_interface_files/cmake/test_interface_files-extras.cmake to reflect proper paths.

What method of installing ROS 2 are you using? It sounds like you are following the "install from fat archive" instructions.

[ahmadnav]

@jacobperron Yes due to #158 I am running an older verstion of dashing (7). But I guess all this is irrelevant if opensplice dependancies are removed entirely from both ros_java and ros_android

[jacobperron]

We can certainly remove OpenSplice as a default dependency from rcljava (and we have in #163). AFAIK, OpenSplice is still a supported RMW for Dashing, so it still might be worth investigating this issue. Though since it has been dropped from ROS 2 Eloquent, I'd say it is not high-priority.

[jacobperron]

Since Dashing is EOL, I'm going to close this. I encourage you to try the main branch with ROS Galactic :)
