I was just started learning Retrofit2 with Moshi but having difficulty during compilation/building.

This is the error from Build Output

 Execution failed for task ':app:kaptDebugKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptWithoutKotlincTask$KaptExecutionWorkAction

This is happening again to me on Kotlin 1.5.21 and 1.5.30 when I include kapt('com.squareup.moshi:moshi-kotlin-codegen:1.12.0') plugin..

Now I can't reproduce it anymore. I'm updating an old project with some old library versions, so it's possible that Moshi was clashing with some old library I updated in the meantime, and now it's working fine..

Sorry for the annoyance.

[IlKor1610]

Upgrade the moshi version to 1.13.0

dependencies {

//Moshi
def moshiVersion = '1.13.0'
implementation "com.squareup.moshi:moshi:$moshiVersion"
implementation "com.squareup.moshi:moshi-kotlin:$moshiVersion"
kapt "com.squareup.moshi:moshi-kotlin-codegen:$moshiVersion"

}
