RoomProcessor compilation or a circular dependency

Question

I've been struggling for days with and issue with Android Room component.

All I did was upgrade my Android studio from 3.3 to 3.4.1, this comes with changes to gradle etc that are done. I've even tried going back to 3.3, but nothing is working. I've have run with Run with --info or --debug option to try see more details but nothing gives me more info. Please help

e: /.../app/build/tmp/kapt3/stubs/debug/com/.../model/HotspotEntity.java:7: error: [RoomProcessor:MiscError] androidx.room.RoomProcessor was unable to process this class because not all of its dependencies could be resolved. Check for compilation errors or a circular dependency with generated code.
public final class HotspotEntity implements android.os.Parcelable {

Versions

Android Gradle:
3.4.1
Gradle version:
5.4.1
Android Room:
def room_version = "2.1.0-alpha06"
implementation 'androidx.room:room-runtime:' + room_version
kapt 'androidx.room:room-compiler:' + room_version
testImplementation 'androidx.room:room-testing:' + room_version

----UPDATE----

Below was tried with room 2.1.0-rc01"which changed it to the same problem but for a different class:

AppDatabase.java:8: error: [RoomProcessor:MiscError] androidx.room.RoomProcessor was unable to process this class because not all of its dependencies could be resolved. Check for compilation errors or a circular dependency with generated code.
public abstract class AppDatabase extends androidx.room.RoomDatabase {

Answer 1

You must include the library:

implementation org.jetbrains:annotations-java5:19.0.0

Because the code which is generated out of the annotations through the kapt plugin, uses org.jetbrains.annotations.NotNull annotation.

It you copy-paste the generated java class is your classpath, you will see the compilation error.

Cheers

Answer 2

From the initial lookup some of your dependencies are old. Please try the following setup ran and tested by me.

Android Studio : 3.4.1

build.gradle (project)

dependencies {
    classpath 'com.android.tools.build:gradle:3.4.1'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.31"
    classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.1.0-alpha05"
    classpath 'com.google.gms:google-services:4.2.0'
}

build.gradle (app)

android {
    compileSdkVersion 29
    defaultConfig {
        targetSdkVersion 29
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    kapt 'com.google.dagger:dagger-android-processor:2.23.1'

    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.31"
    implementation 'androidx.core:core-ktx:1.0.2'

    implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0-alpha01'
    implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.2.0-alpha01'
    implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0-alpha01'
    implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.0.0'
    kapt 'androidx.lifecycle:lifecycle-compiler:2.2.0-alpha01'

    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'

    //DI
    implementation 'org.koin:koin-android:1.0.2'
    implementation 'org.koin:koin-androidx-scope:1.0.2'
    implementation 'org.koin:koin-androidx-viewmodel:1.0.2'

    implementation 'org.greenrobot:eventbus:3.1.1'

    //Coroutines
    implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.1.1'
    implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.1.1'

    //Database
    implementation 'androidx.room:room-runtime:2.1.0'
    kapt 'androidx.room:room-compiler:2.1.0'
    testImplementation 'androidx.room:room-testing:2.1.0'
}

Answer 3

I had run into the same problem, and comparing the OP's gradle file with mine, I found that both contained

configurations {
    cleanedAnnotations
    compile.exclude group: 'org.jetbrains', module: 'annotations'
}

By removing it, Room's annotation processing started to work.
