Plugin 'org.jetbrains.kotlin' failed to initialize and will be disabled. Please restart Android Studio

Question

After Android Studio's Kotlin plugin update, It stopped working. Plugin is getting disabled automatically. Below error I am getting.

com.intellij.openapi.extensions.impl.PicoPluginExtensionInitializationException: Duplicate registration for EP: org.jetbrains.uast.uastLanguagePlugin: original plugin com.intellij, new plugin org.jetbrains.kotlin

Answer 1

To solve this issue, you have to either upgrade or downgrade your kotlin plugin

Solution 1: Upgrade Plugin

First go to Tools menu > Select Kotlin > Configure Kotlin Plugin Updates > Select one of the kotlin plugin & press download (stable or early access, i chose early access to solve this issue)

And finally change the kotlin version in build.gradle(Project:) according to the downloaded version

Solution 2: Downgrade Plugin

If your on mac then press: Command + , to open preference, then select plugin & search for kotlin & uninstall it, it will rollback to previous version: 1.1.51

On Windows machine, press Control + Alt + S to open settings dialog, then select plugins & search for kotlin & uninstall it, it will rollback to previous version: 1.1.51

Please Note: Do not uncheck kotlin in plugins else it will disable kotlin & fail to recognise kotlin file & syntax

Answer 2

If upgrading doesn't help try downgrading

when i faces the same issue with Android studio 3.1 Canary 5 with Kotlin version v1.2.10-release-IJ2017.1-1 (latest version as on 15 dec 2017) I tried the above solution which didn't work so i just uninstalled the update and it reverted back to version 1.1.51 and that worked without any issue
