Have you tried official documentation?
yes. https://www.traccar.org/build-in-intellij-idea/
This is the older version of intelliJ. The version I have is 2019.
The documentation is for newer version. Why are you using older version?
ok thank you. I see the newer version is 2020.2.3. I will download and follow the steps.
Can I get the setup to launch traccar from IntellJ. I downloaded the source from Github. Also the configuration settings main class and program arguments. . I searched on this forum, and the IntelliJ is a older version.
