Graal SDK works when the application runs but fails in unit test

Question

I'm using Graal SDK in order to "translate" an R script to Java code.

The line is compiled and behaves well when the application runs:

Source.newBuilder("R", new File(config.defaultScriptPath)).build()

However, once a unit test that executes this line runs, I get an error:

java.lang.IllegalStateException: No language and polyglot implementation was found on the classpath. Make sure the truffle-api.jar is on the classpath.

Does anyone know how I can resolve this error?

Answer 1

Solved by ensuring that GraalVM is used by setting JAVA_HOME
