Compiling Problems: about synthea

[dehall]

It looks like the version of gradle that we have bundled with Synthea doesn't support these more recent versions - we should explore updating to a newer version of gradle and provide more guidance on supported versions of Java.

@BOTwinnik in the meantime can you try with JDK 17? 17 is the current LTS (long-term support) version and will be actively supported for 3 more years

I ran into the "Unsupported class file major 64" while trying to install on a fresh laptop last week. Reverting to JVM 17 helped, but then I ran into the problems documented in #1336.

You may need to patch the build.gradle file, as specified in #1337

[BOTwinnik]

Thank you both for the quick reply! I will check for JDK 17 and let you know, whether it worked out.

@BOTwinnik I'm going to assume this issue is resolved and close it. Feel free to re-open it if you're still seeing the error.

Note also that we made a recent update and Synthea now supports JDK 19, so another potential fix is to get a fresh copy of synthea and try again.
