Ant javascript tags don’t work on Big Sur Our ant script doesn’t work on our new M1 build machine doesn’t work because it has a javascript tag, and it javascript (Nashorn) was removed from Java in Java 15.
build.xml:5: Unable to create javax script engine for javascript
Java 15 has removed Nashorn, you must provide an engine for running JavaScript yourself. GraalVM JavaScript currently is the preferred option.
I have searched all over for a Nashorn or Graal that works with Java15 but can’t find anything. The https://github.com/graalvm/graalvm-ce-builds/releases skips from Java11 to 16.
Any idea how get our javascript tags working again?
