How to pass compiler plugin options?

[NeonMika]

Hello!

I want to also use my commandLineProcessor together with my compilerPluginRegistrar, yet I struggle to provide the compiler plugin options (in the form of -P plugin:<plugin id>:<key>=<value>) to the compiler.

What I have tried so far:

// ...
KotlinCompilation().apply {
        sources = sourceFiles
        commandLineProcessors = listOf(MyCliProcessor())
        compilerPluginRegistrars = listOf(MyCompilerPluginRegistrar())
        // how do I pass compiler plugin options?
        // neither of the following works:
        // kotlincArguments = listOf(""-P plugin:mypluginid:enabled=true")
        // kotlincArguments = listOf(""-P plugin:com.tschuchort.compiletesting.maincommandlineprocessor.mypluginid:enabled=true")
        // kotlincArguments = listOf(""-P plugin:com.tschuchort.compiletesting.maincommandlineprocessor:mypluginid:enabled=true")
}

Providing no compiler plugin option results in the following error, thus I came up with the above mentioned versions:

e: Required plugin option not present: com.tschuchort.compiletesting.maincommandlineprocessor:myplugin:enabled

Plugin "com.tschuchort.compiletesting.maincommandlineprocessor" usage:
  mypluginid:enabled <true|false>
                             whether plugin is enabled (required)

Can you help me to correctly configure my commandLineProcessor?

Thank you!

Best,
Markus
