Failed to resolve variable '${project.groupId}'

Failed to resolve variable '${project.groupId}'

error: package android.support.annotation does not exist
failed to transform artifact parceler jar
migrate to androidx
project needs to be converted to androidx dependencies
dependencies using groupid com android support and androidx
enablejetifier
settings activity requires androidx support
butterknife androidx

I migrate my project to AndroidX and I got these errors when building the project:

[TAG] Failed to resolve variable '${project.groupId}'   
[TAG] Failed to resolve variable '${project.version}'   
[TAG] Failed to resolve variable '${project.groupId}'   
[TAG] Failed to resolve variable '${project.version}'   
[TAG] Failed to resolve variable '${project.groupId}'   
[TAG] Failed to resolve variable '${project.version}'   

I already tried several possible solutions:

  • Clean Project
  • Invalidate Cache and Restart
  • Set enableJetifier to false
  • Add option --refresh-dependencies to the compiler settings

Here is my project gradle file:

buildscript {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
        google()
        maven {
            url 'https://maven.fabric.io/public'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        classpath 'com.google.gms:google-services:4.0.0'
        classpath 'io.fabric.tools:gradle:1.25.4'
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://jitpack.io'
        }
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
}

task clean(type: Delete) {

UPDATE

I run gradlew assembleDebug --stacktrace --debug --info and here are some more info:

...
Caused by: org.gradle.api.artifacts.transform.ArtifactTransformException: Failed to transform file 'dagger-compiler-2.2.jar' to match attributes {artifactType=processed-jar} using transform JetifyTransform
...
Caused by: java.lang.RuntimeException: Failed to transform 'C:\Users\me\.gradle\caches\modules-2\files-2.1\com.google.dagger\dagger-compiler\2.2\e411f732e5cd9697cdb291f6073b0d6ee2352023\dagger-compiler-2.2.jar' using Jetifier. Reason: The type does not support '.' as package separator! Received 'java.lang.Object;Ljava.lang.Class'.. (Run with --stacktrace for more details.) To disable Jetifier, set android.enableJetifier=false in your gradle.properties file.

So it seems jetifier and dagger are the cause, but jetifier is necessary for the migration to AndroidX and I don't want to remove dagger.

If I set android.enableJetifier=false I have more than 50 issues about DataBinding.

What I did to solve this is File - Invalidate Caches/Restart.

I got the same error after updating my build.gradle file with AndroidX Test dependencies. Turns out I forgot to remove the old junit dependency.

The one more reason is Jetifier tries to jetify libraries that it isn't suppose to. Starting with Android gradle plugin 3.3.0-rc01 and 3.4.0-alpha04 there is a workaround to disable jetifying specified libraries by adding them to coma-separated list at gradle.properties:

android.jetifier.blacklist=byte-buddy,guava

The solution is found here
