Dashbing branch build error: ‘rosidl_generator_java::msg::dds_’ has not been declared

[xingjl6280]

Hi team,

I was able to build and run examples previously followed by the branch: update-readme

But now, for a new environment, I got below build error. I guess it's due to the 25thNov ros upgrade, as I found below package version difference. Is there a workaround for now?

thank you

I am getting the same error, any luck?

no luck at all :( I'm giving up and considering to use the ros1 solution: zmq + protobuf + zeroconfWe spent too much time on dashing java and Android client-------- 原始邮件 --------发件人： ahmadnav notifications@github.com日期： 2020年12月14日周一 11:42收件人： ros2-java/ros2_java ros2_java@noreply.github.com抄送： xingjl6280 xingjl6280@163.com, Author author@noreply.github.com主 题： Re: [ros2-java/ros2_java] Dashbing branch build error: ‘rosidl_generatorjava::msg::dds’ has not been declared (#156) I am getting the same error, any luck?

@xingjl6280 the opensplice rmw implementation is no longer supported in ROS 2 (or at least it's not actively maintained), could you try removing ros-dashing-opensplice-cmake-module and any of the other opensplice packages? Thanks.

[xingjl6280]

thanks Steve,

it's working now, by removing dependence rosidl_typesupport_opensplice_c from ros2_java/ros2_java/rosidl_generator_java/package.xml
