"Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.5.1, expected version is 1.1.16"

Question

I am a beginner in Kotlin app development. The following error occurs when I tried to build the app:

C:/Users/Lenovo/.gradle/caches/transforms-2/files-2.1/32f0bb3e96b47cf79ece6482359b6ad2/jetified-kotlin-stdlib-jdk7-1.5.0.jar!/META-INF/kotlin-stdlib-jdk7.kotlin_module: Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.5.1, expected version is 1.1.16

Is it about updating the module? Then how to update it?

Answer 1

For someone who is still looking for answer to this, here is the working solution for this problem. In your project level open build.gradle file, increase the ext.kotlin_version from whatever current version that you have like 1.5.0, to the latest stable version 1.6.0 (Whatever is latest at that time). Thanks

You can get latest version from here:

Answer 2

Happened to me when updating from Kotlin 1.4.30 to 1.5.0. Seems to be some sort of Gradle caching issue. I was able to resolve it by updating Gradle from 6.7.1 to 6.9 (or any other version).

Just go to gradle-wrapper.properties and change this line from

distributionUrl=https://services.gradle.org/distributions/gradle-6.7.1-all.zip

to

distributionUrl=https://services.gradle.org/distributions/gradle-6.9-all.zip
