Hi, thanks for reporting this. Looks like Java 23 isn't supported by the version of Gradle we're using. We'll try to upgrade that asap, but in the meantime to get synthea working you may want to try a couple things:

1. Use an earlier version of Java such as Java JDK 17 which is known to work
2. Use the prebuilt JAR as described here: https://github.com/synthetichealth/synthea/wiki/Basic-Setup-and-Running
