# compiler

Stupid question - I’m trying to write a hello world compiler plugin and apparently it is not being invoked. How would you go to debug this situation? I can see that the provider lambda returned by
is invoked, so kotlin is preparing the args to be passed to the plugin. There I have a command line processor and an IrGenerationExtension. I’m adding all kinds of logs - println(), error(“Hello world”), send stuff to createDiagnosticReporter(). But I get nothing, compilation succeeds. Not sure what to do, maybe there is some compiler flag that can give me more information?

Ensure that the plugin ID you're passing is consistent. You can also use something like kotlin-compile-testing to see if your plugin would work normally not through Gradle. If it doesn't work in kotlin-compile-testing, then something is wrong with your ComponentRegistrar, but if it works, then check your gradle plugin.

Thanks Youssef! I finally solved it. It would be very useful to have an option in gradle that prints the actual kotlinc invocation. I could not find it. (what went wrong if you’re curious - I was testing with a native target, and if you have kotlin.native.useEmbeddableCompilerJar=true (default from 1.7), you don’t need to override getPluginArtifactForNative(). I was on 1.7, but I discovered that a third party gradle plugin, added the old way (buildscript block, classpath configuration) was actually downgrading the version to 1.6.21)
