Error:(46, 0) Could not find method kotlin() for arguments [build_4fp1tow4qcx2530bdrl2gp05n$_run_closure2$_closure19$_closure20@78ae7c54] on source set 'main' of type org.gradle.api.internal.tasks.DefaultSourceSet.

so… after uninstalling Kotlin plugin, you may remove that line about kotlin from the defaultSourceSet… doesn’t you?

I uninstalled the plugin

Then I’m afraid I couldn’t help you… sorry.

Intellij installed this plugin

I will remove the

kotlin { srcDirs = [] }

from gradle file.
