Rosjava Pub_Sub_tutorial - No binaries? No proper code? [closed]

edit

Hello there,

I followed the rosjava tutorials here: wiki.ros.org/rosjava_build_tools/Tutorials/hydro/Creating%20Rosjava%20Packages#RosJava_Catkin_Packages, created a subproject like this: wiki.ros.org/rosjava_build_tools/Tutorials/hydro/WritingPublisherSubscriber%28Java%29.

Two things, one minor and one major happend:

The minor one ist, that after creating the rosjava package and doing the first catkin_make, I get the following error:

FAILURE: Could not determine which tasks to execute.

* What went wrong:
Task 'uploadArchives' not found in root project 'rosjava_pkg_a'.

* Try:
Run gradlew tasks to get a list of available tasks.

BUILD FAILED

I guess this is because no projects are in the package at this point? I could continue the tutorial from that point without problems, the setup.bash file got created. It is just confusing for a newcomer to gradle/rosjava/catkin to see such errors. Where would I have to adress this issue? At the github repository or here?

The second and major problem is, that when I continue the tutorial to the point where I create the pub_sub_tutorial, "only" this happens:

~/workspaces/tutorial_workspace/src/rosjava_pkg_a$ catkin_create_rosjava_project my_pub_sub_tutorial

Creating rosjava project 
  Name      : my_pub_sub_tutorial
  File      : build.gradle
  File      : settings.gradle
  File      : Dude.class

Now as I said I am new to the gradle-world, but shouldn't there be more files for the tutorial to work? Or should those be downloaded while running the catkin_make? Here is the output:

According to the tutorial, there now should be an install-folder under my_pub_sub_tutorial/build, but all I got is an ivy.xml.

How serious are the errors in my catkin_make?

Did I do something wrong or is the tutorial out of date?

Also, as a guy who is used to pressing "play" in eclipse and watching everything work out on its own, is there a tutorial/introduction to the whole world of makefiles and project-infrastructure you can recommend?

Thanks in advance!

Update:

My package.xml says I am on version 0.2.0, git pull origin executed in the "build_tools" directory tells me I am up to date. But if I compare the cmake/rosjava.cmake.em file, it seems to me that I still have the old version (Line 74 is still # Note : COMMAND is a list of variables (semi-colon separated ...
