Installing ROS2 - Fast-RTPS-Gen installation error

Hey,

i am trying to install ROS 2 (dashing) as described here

To do that, (if I get that right) I need to install Fast-RTPS and Fast-RTPS-Gen first. The installation of Fast-RTPS is successfull but when I try to install Fast-RTPS-Gen I get the following error:

~/Fast-RTPS-Gen$ gradle assemble

FAILURE: Build failed with an exception.

* Where:
Build file '/home/falke/Fast-RTPS-Gen/build.gradle' line: 23

* What went wrong:
Could not compile build file '/home/falke/Fast-RTPS-Gen/build.gradle'.
> startup failed:
  build file '/home/falke/Fast-RTPS-Gen/build.gradle': 23: unable to resolve class org.gradle.api.tasks.options.Option
   @ line 23, column 1.
     import org.gradle.api.tasks.options.Option;
     ^
  
  1 error


* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 0s

Can someone please help me. I searched on google, but I dont know how to solve the problem.

Best regards

Okay, I guess I get it working. I had still files of an old version of gradle and also some old fastrtps files which might caused the error. After deleting them I was able with sudo env path=$path_to_gradle6.5 gradle install
to install fastrtps gen.

I followed the installation steps for ROS2 here.

  • I have installed ros dashing and melodic.
  • Gradle 6.5
  • Kotlin: 1.3.72
  • Groovy: 2.5.11
  • Ant: Apache Ant™ version 1.10.7 compiled on September 1 2019
  • JVM: 1.8.0_252 (Private Build 25.252-b09)
  • OS: Linux 5.3.0-59-generic amd64

Now I am getting the following error:

There seems to be still an error with the mircortps_agent. What can cause this error? Any suggestions? Help?

Thanks!
