Hello,

My question is quite simple but I don't figure out how to do, I get no issue to compile ros2_java by running procedure described in this repository

cd /src/ros2_java_ws
source /opt/ros/${ROS_DISTRO}/setup.bash \ 
    && curl -skL https://raw.githubusercontent.com/ros2-java/ros2_java/main/ros2_java_desktop.repos -o ros2_java_desktop.repos \
    && vcs import src < ros2_java_desktop.repos \
    && rosdep install --from-paths src -y -i --skip-keys "ament_tools" \
    && colcon build

All examples work fine but just if I try to build them outside the ros2_java_ws, it failed

mkdir -p /src/test/src
cp -r /src/ros2_java_ws/src/ros2-java/ros2_java_examples/ /src/test/src
cd /src/test
source /opt/ros/${ROS_DISTRO}/setup.bash
source /src/ros2_java_ws/install/setup.bash
colcon build --event-handlers console_cohesion+

with

[...]/SubscriberMemberFunction.java:18: error: cannot find symbol
import org.ros2.rcljava.RCLJava;

If someone have the solution, which must not be so complicated as everything work fine in the ros2_java_ws, it will be greatly appreciated :)

My environment:
Ubuntu 22.04
ROS2 Humble
JAVA 11
Gradle 6.0

And the full log of colcon build

For those with the same problem and before adding a most valuable solution, a working hack:

1- add to build.gradle


ext {
    ROS2_JAVA_CP = files(System.getenv("ROS2_JAVA_CLASSPATH").split(File.pathSeparator))
}

compileJava {
  doFirst {
    classpath += ROS2_JAVA_CP
  }
}

then before colcon build

source /opt/ros/humble/setup.bash
source /src/ros2_java_ws/install/setup.bash
export ROS2_JAVA_CLASSPATH=$CLASSPATH
colcon build
