3 years ago Due to resource limits, our plan for the ros2-java project is to only target the latest ROS release (currently, Galactic). Since there are no plans for maintainers to look into Foxy support, I'm going to close this.
That being said, I'm happy to support any community effort to get this working for Foxy. I recommend trying the latest changes on the main branch and if that doesn't work you can try going back to an earlier commit (maybe this one: fe96b5e8cb375e2863ff13fe397ca95d9b9856ff).
I tried to compile the package with Ubuntu 20.04 ROS Foxy and did the things, which are mentioned at the README In package rosidl_generator_java I got an error
Find attached my stacktrace:
