"Unable to create javax script engine for javascript" extjs

Question

Following the "default" installation of extjs, I can't get it running with any Java > version 14.

With Java 14 the main warning is:

[ERR] Warning: Nashorn engine is planned to be removed from a future JDK release

With Java 15 the ant build is failing:

Any way to fix this?

I had same issue, but with Java 17.

I changed Java to version 8 and I restarted all terminals and it resolved my problem.

Yes, its a workaround, not quite a solution, we want to move forward not backward. – klodoma Mar 10 '23 at 10:23
I use the same workaround but with Java 11 which is also an LTS release. – giraffe Aug 05 '23 at 19:27
