I haven't been able to get Jackpot to build... (If there is a better place
to ask about this, let me know)
I followed the instructions in cmdline/README.md
Using Ant v 1.10.12
Maven v 3.8.4
With JAVA_HOME set to JDK 8
I ran:
ant -DNETBEANS_PLATFORM=/Users/scott/dev/netbeans-13
-DJDK11=/Library/Java/JavaVirtualMachines/zulu-11.jdk/Contents/Home
-DJDK17=/Library/Java/JavaVirtualMachines/zulu-17.jdk/Contents/Home
build-and-test
It chugged away for a bit but then failed a bunch of tests:
[junit] Testcase:
testConfigurationFile(org.netbeans.modules.jackpot30.cmdline.CreateToolTest):

Basically a few like above, and then a lot more that looked like this:

Any hints are appreciated.
