The JAR file deployed on Maven Central using the following coordinates is having a META-INF/services folder, but inside that one it is missing the javax.script.ScriptEngineFactory files. As a result, the JAR file cannot simply be put on the classpath to enable JavaScript using JSR 233, which is a major drawback!

We should immediately publish version 15.0-1 as a corrected rebuild which is 15.0 plus that missing file.
