I might have missed something, but based on the wiki and tutorial of Rosjava, I can not figure out how to run the tutorial code of Rosjava_tutorial_pubsub.

I compiled rosjava with Gradle (earlier have tried to install from Ubuntu repository as well as compiled with Rosmake).

  1. There is no in rosjava_bootstrap, so that I cannot use the command from the tutorial: rosrun rosjava_bootstrap <> <*>

  2. Also, Rosrun won't find any executable from rosjava_tutorial_pubsub.

Any idea or link that can help?

The script is no longer used since the switch to Gradle. Instead, rosjava_tutorial_pubsub creates an executable jar using Gradle's Application plugin. See the documentation which describes how to execute the Talker and Listener nodes from the pubsub tutorial:

Also make sure to follow the documentation on installing and building rosjava_core:

Hello guys,

i also have a problem to build and run the pubsub tutorial project. I followed that tutorial but the step "Executing nodes" doesn't work for me unfortunatelly. The build process (../gradlew installApp) runs without any errors but there is no path "/rosjava_tutorial_pubsub/bin/rosjava_tutorial_pubsub" in directory build. Even the executable nodes (Talker and Listener) cannot be found anywhere in the project. Isn't the tutorial up to date or may this be a bug?

Edit: In the consoleoutput I found that warning when the build process is building rosjava_tutorial_pubsub project:

warning: [options] bootstrap class path not set in conjunction with -source 1.6

That warning appears for several projects in the rosjava_core folder (e.g. rosjava_bootstrap, rosjava_messages, etc.). May this be the reason for the problem?

is there any consensus on how to run the pubsub tutorial for rosjava post the switch to gradle? I can't get the above 'dirty workaround' to work, and am not sure how to otherwise run this tutorial. (I have successfully installed and compiled rosjava_core using ./gradlew install). Is the jar created by the pubsub tutorial supposed to be executable? If i run

java -jar rosjava_tutorial_pubsub-0.0.0-SNAPSHOT.jar

i get:

no main manifest attribute, in rosjava_tutorial_pubsub-0.0.0-SNAPSHOT.jar
