Factory Island

Getting the source

This project was written in Eclipse 2022-12 and JDK 17. It's better to use an eclipse integrated JDK, so it doesn't interfere with anything installed system-wide.
Eclipse -> Import... -> Existing Maven Project
Set JRE System Library to JavaSE-17 in the build path
Add -Xmx4G -XX:+UseZGC -Dsun.java2d.d3d=false (Windows) -Xmx4G -XX:+UseZGC -Dsun.java2d.opengl=True (Linux) to VM arguments in the Run Configuration

Building on Linux

Download platform-specific JRE 17 packages (Eclipse Temurin for example) into /target/openjdk. Filenames need to be jre_win64.zip, jre_mac.tar.gz, jre_linux64.tar.gz.
Right click pom.xml -> Run As -> Maven install
Exported packages will be in /target/export
