If you are not sure if this code is safe to compile and run, you can read through every line of code, and compile it with the below instructions. You can also see the commit history by clicking on the (n) commits button, to make sure nobody has added any exploits or introduced vulnerabilities to the code.
If you find any exploits, security issues, etc in the code, please send me an issue or pull request and I will try to respond to it as soon as possible.
Make sure you have a Java 21 JDK installed (this may not work for newer JDK versions), then run "./gradlew build" for Unix(-like) OSes or "gradlew.bat build" for Windows. If the build was successful, the compiled JAR file should be in "build/libs".
