Detekt custom rules that uses Type resolution doesn't work with IntelliJ plugin

[skymansandy]

Hi team,

I've created some custom rules. Few that use type resolution and few that don't. In the IntelliJ Plugin, rules that don't need type resolution works fine when I add the plugin jar. But the type resolution ones don't. Is this expected?

Thanks.

Is this expected?

Are they working fine if you invoke Detekt from CLI or from Gradle?

Hey @cortinico, Yes, while running the Gradle task it's working fine.

This is actually reported by users. ConfiguredService does not invoke Detetkt with BindingContext, therefore, type resolution rules do not work and mixed type resolving/plain rules may result in weird behavior.

It is reported that UnusedPrivateMember is such a rule with mixed behavior: https://kotlinlang.slack.com/archives/C88E12QH4/p1624326624052100

Hey, I would love to help, but might need a hint. I assume that if we set the classpath via compiler options, rules with type resolutions are executed.

Do you know how to get the classpath in the plugin?

I googled a bit, read some javadocs and tried with:

        ModuleManager.getInstance(project).modules
            .map { OrderEnumerator.orderEntries(it).recursively().getPathsList().getPathsString() }
            .filterNot { it.isNullOrEmpty() }
            .joinToString { ":" }

which gives me an empty string.

Rules like ForbiddenMethodCall, ForbiddenImport are not working with the plugin.

Yea, also just noticed that built-in rules that require type resolution are not working.

It's not just custom rules, btw, as per https://github.com/detekt/detekt-intellij-plugin/issues/499.
