Roland posted this announcement in the comments under my psimulator2 blog post. So that his announcement receives a bit more visibility, I am re-posting his comment verbatim below:
Just a heads up, I forked the project from the original, seemingly discontinued source and it is available at https://github.com/rkuebert/psimulator .
I have fixed the issue preventing the use of Java 8, but I have yet to look into making a release on GitHub. You can, however, clone the repository and use gradle to build jar files – I recommend using
gradle shadowJarto create jar files which can be run without specifying any further dependencies.
For the frontend, use
java -jar java -jar frontend/build/libs/psimulator-frontend-master-*.jar(replace the asterisk with the exact name, the star represents the git commit you used to checkout).
For the backend, use
java -jar backend/build/libs/psimulator-backend-master-*-all.jar(replace the asterisk with the exact name, the star represents the git commit you used to checkout).
