A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution > java.lang.reflect.InvocationTargetException (no error message)

Android Studio's UI was just hiding the error...

when the error occurred, it highlighted the item in the list view, and showed an unhelpful message in the terminal view.

to find the real error, select the root item in the list view so that Android Studio would display the whole build output in the terminal view, then scroll to find error.

I develop in Apple Silicon Macbook M1.

use room_version 2.2.4, fails in 2.2.5

def room_version = "2.2.4"

implementation "androidx.room:room-runtime:$room_version"
kapt "androidx.room:room-compiler:$room_version"
implementation "androidx.room:room-ktx:$room_version"
testImplementation "androidx.room:room-testing:$room_version"

You need change:

kapt "android.arch.persistence.room:compiler:$room_version"

to

kapt "androidx.room:room-compiler:$room_version"

This exception occurs when you have done some mistake on Room database or Doa or entity class for example I had done mistakes in the entity class

1. I had made the autogenerated field of Entity class val instead of var
2. I had put delete annotation on two functions with a different name but they were deleting the same data

so I would suggest to check the entity,dao or database class carefully if you imported the right dependency.

@Entity(tableName = "user_table")
data class User(
    val firstName: String,
    val lastName: String,
    val age: Int
) {
    @PrimaryKey(autoGenerate = true)
    var id: Int = 0 //**do not made it val**
}

I'm currently having this error on m1 Mac with Room version 2.3.0.

I fixed it by changing it to 2.4.0-alpha04.

This has been reported to Google (issue tracker).

Today I faced this error. In my case, I have both java 11 and java 16 installed in my laptop, and java 16 was the default. But the gradle in my project uses java 11 to build it. So when I invoked

$ gradle build

from my terminal, it would use java 16 and so the build failed. I know, the proper solution is to make my code compatible with java 16, but for now, I am explicitly telling gradle to use java 11 using the following command:

$ gradle build -Dorg.gradle.java.home=/usr/lib/jvm/java-11-openjdk-amd64 # warning: use te path to your java 11 

Since it is a large command, I saved it in a script file and so simply running the script solves the problem for me.

Try to add this in your app/build.gradle file and run the program again. It helped me to find the real cause of the issue.

kapt {
    correctErrorTypes true 
} 

I might be late but only following solution worked for me.

Open gradle.properties file in Android studio.

Add following lines:

kapt.use.worker.api=false
kapt.incremental.apt=false

Clean & Re-build the application.

Done

I had faced the same issue. The problem was because I was using coroutine suspend functions in the Room DAO and had not implemented the necessary implementations. The following worked for me, try replacing the existing Room dependencies with:

def room_version = "2.2.5" //Use latest version

"androidx.room:room-runtime:$room_version"
"androidx.room:room-compiler:$room_version"
"androidx.room:room-ktx:$room_version"

If the above does not work, go to Analyze->Inspect Code and check for code-breaking warnings or errors(Specifically in Room)

I had to update Room to latest 2.2.5 and it has resolved the issue.

This issue occurred on package renaming I've dragged and dropped all files from one package to other.

Objectbox it created the cursor files and entity files (auto-generated files)

Had to delete them and re-built.

It ate up 1 hour straight -_-

Make sure Gradle JDK is set to the correct version (it was set to JDK 8 even though I've been using JDK 11 for quite some time now).

Open Preferences -> Builds Tools -> Gradle -> Set Gradle JDK.

Image of Gradle JDK in Android Studio

Make sure to include all entities inside the Database annotation.

I updated the Room version from 2.2.5 to 2.3.0 or to current version in the build.gradle script file. The build was successful.

Update the gradle JDK to java 11.

You have to use gradlew assemble --stacktrace in terminal to get more detailed error log.

If you're on Mac, then run this instead ./gradlew assemble --stacktrace

There's an error that is in your files, but the editor cannot show you because the file is closed and hasn't been analysed.

This mostly occurs when you amend some data classes/POJOs and your app has several layers that depend on each other.

As the dependency goes up, some functions cannot infer data types and returns this kind of an error.

1. Command+Click on the modified data classes and see where they are being used, you may possibly find the error there.
2. Open your files one by one, you don't have to hang on there and wait for the editor to finish analysing(If your editor takes some time to), as the editor analyses, the errors will be displayed and you can fix them and have a successful build.

There's the option of Code -> Analyse code on android studio but sometimes it doesn't work as expected, you may try this - just incase.

In my case I gave the argument type of insertAll() and delete() function as Entity ofyour database, the Error Solved

@Dao
interface NotesDao {

    @Insert
    fun insertAll(INotesEntity: NotesEntity) // argument type should be entity of your database

    @Delete
    fun delete(DNotesEntity: NotesEntity)    // argument type should be entity of your database

}

While it's rather strange, I had onDestory defined two times in one file and caused this error when trying to run the app, once i deleted one of them everything worked normally.

When I faced this issue, it was about data-binding in an XML file. I deleted a code using backticks `` and changed it into string interpolation.

The only thing that worked for me -

In gradle.properties replace the following line -

org.gradle.jvmargs=-Xmx2048m -Dfile.encoding=UTF-8

by

org.gradle.jvmargs=--illegal-access=permit
