To fix the IDE build, try the following:.If everything goes well, then your environment is all good to work with Kotlin. If anyone stumbles across this and NEITHER Invalidate Cache or Update Kotlin's Version work:įirst, make sure you can build it from outside the IDE. The option, per module, Kotlin -> FIX does not exist anymore and has been that way for years now since this was a temporary patch to deal with integration issues during the early previous releases. The jetbrains thread regarding this issue has moved and is nowhere to be found, so the link below is not valid anymore. If you still have issues, with some older plugins you need to clear the caches in Intellij IDEA (file menu, Clear Caches and Restart, select option to restart). For example if IDE plugin is Beta 1, but your Gradle/Maven project using M12, you'll have issues exactly as you described. Project gradle: ext.kotlin_version = '1.1.1'Ĭlasspath ':gradle:2.2.2'Ĭlasspath ':kotlin-gradle-plugin:$kotlin_version'Ĭlasspath ':kotlin-android-extensions:$kotlin_version'Ĭompile fileTree(dir: 'libs', include: )ĪndroidTestCompile('.espresso:espresso-core:2.2.Your Intellij IDEA plugin and the Kotlin runtime/compiler that you use in the project need to match. See log for more detailsĮrror:(12, 21) Unresolved reference: DaggerAppComponent However, now the compiler complains : Error:(5, 32) Unresolved reference: DaggerAppComponentĮrror:Execution failed for task ':app:compileDebugKotlinAfterJava'. Before Kotlin was installed I had no issues with Dagger. I have installed Kotlin plugin today into an existing project with Dagger 2. N:B: i tried changing from kapt to annotationProcessor, and thought the project compiled, i still couldn't generate DaggerAppComponent I don't know if there's an official fix to this yet, but this might help someone. So as a fix, i added: kapt ':kotlinx-metadata-jvm:0.2.0' I found out that this is because Dagger uses the old version of kotlinx-metadata-jvm library & doesn't support kotlin version 1.5 and above yet. IllegalStateException: Unsupported metadata version' in When i used Run with -stacktrace i found out that the issue was:

Implementation ':dagger-android-support:2.28.3' When you try to run the project using implementation ':dagger:2.35.1' There's an issue with dagger 2 (above versions) and kotlin 1.5.30.
