Execution failed for task ':app:kaptGenerateStubsDebugKotlin' after android studio V3.1.1 update

Question

I just updated android studio to V3.1.1. Then my program went wrong. When build the program,there are two errors:

1. One in 'Run build':

   org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:kaptGenerateStubsDebugKotlin'

2. Another in Java compiler:

java.lang.ClassNotFoundException: org.jetbrains.kotlin.resolve.checkers.SimpleDeclarationChecker enter image description here

Here is my gradle:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'

apply plugin: 'kotlin-android-extensions'




android {
    compileSdkVersion 26


    defaultConfig {

Answer 1

Well,I finally get over this. When I use --stacktrace,I find the :app:kaptDebugKotlin is a procedure in BUILDING an android program. --stacktrace result picture

And I get the error java.lang.ClassNotFoundException: org.jetbrains.kotlin.resolve.checkers.SimpleDeclarationChecker in this :app:kaptDebugKotlin procedure.

I doubt that there're something new in kotlin implementation,so I update my kotlin_version from 1.2.21 to 1.2.30.

Then I get more clear errors.That is the room parameters errors. room error

So I change the arg0 to the parameter name in Dao functions in SQL query.

Finally it works.
