Exception in thread "main" java.lang.IllegalArgumentException: Could not find option with name inspect.

I have

implementation 'http://org.graalvm.tools:chromeinspector:23.0.8'

in my build.gradle.

I assume the "http://" part is just some crap Disqus added? 🙂

Does the 23.0.8 version match the GraalVM version you're running this under?

I've resolved it. The issue was because polygot was unable to resolve the classes correctly because I was building an uber jar.

My GraalVM version is 24.2.0

Yeah. The "http://" part is Disqus.

That's still the highest version. The other one on Maven is org.graalvm.tools:chromeinspector-tool:24.1.1 which causes the following panic whenever I set the inspect option.
