figure out how to do, I get no issue to compile ros2_java by running procedure described in this repository\r\n\r\n```\r\ncd /src/ros2_java_ws\r\nsource /opt/ros/${ROS_DISTRO}/setup.bash \\ \r\n    \u0026\u0026 curl -skL https://raw.githubusercontent.com/ros2-java/ros2_java/main/ros2_java_desktop.repos -o ros2_java_desktop.repos \\\r\n    \u0026\u0026 vcs import src \u003c

try to build them outside the ros2_java_ws, it failed\r\n\r\n```\r\nmkdir -p /src/test/src\r\ncp -r /src/ros2_java_ws/src/ros2-java/ros2_java_examples/ /src/test/src\r\ncd /src/test\r\nsource

error: cannot find symbol\r\nimport org.ros2.rcljava.RCLJava;\r\n```\r\n\r\nIf someone have the solution, which must not be so complicated as everything work fine in the ros2_java_ws, it will be greatly appreciated :)\r\n\r\nMy environment:\r\nUbuntu 22.04\r\nROS2 Humble\r\nJAVA 11\r\nGradle 6.0\r\n\r\nAnd the full log of colcon build\r\n```\r\nStarting \u003e\u003e\u003e
