transformClassesWithDesugar build error after updating to AS 3.0 Canary 6

Question

I updated to Android Studio 3.0 Canary 6 and am now getting following error (had been on Canary 5). I\'ve searched for people seeing similar issues but no luck so far. Any

Answer 1

For me, it happened with AS3.0 stable, with classfiles from previous beta version. The solution was to do a Build -> Clean Project.

Answer 2

For those who encounter this problem on an ionic or cordova project this command will help you:

cordova clean android

Answer 3

With Android Studio 3.1, com.android.tools.build:gradle:3.1.0 and gradle-4.4-all.zip this issue resolving with adding

android.enableD8.desugaring = true

in gradle.properties file.

Answer 4

Have you tried https://github.com/gradle/gradle/issues/2384#issuecomment-376793947 ?

Try adding android.enableD8.desugaring = true in gradle.properties and you may need to add proguard rule -dontwarn java.lang.invoke**

Answer 5

This seems to be a gradle bug.
Just update your gradle (/gradle/wapper/gradle-wapper.properties) manually and try build again to find more helpful infomation.

Here is how I solved my problem as this may be helpful.

I'm using AndroidStudio 3.0.1 with embedded gradle 4.1-all (Newly installed), and a project which worked fine yesterday.

I guess it's a Gradle problem so I upgraded my Gradle wapper manually to 4.4.1-all (2017/12/29, the last release version in http://services.gradle.org/distributions/), then cleaned and built again.

Sadly, this exception appeared again, but with more information:

This message helped me to fix the problem: I'm using jooR in my project, and it told me something's wrong with it, so I checked http://mvnrepository.com/search?q=joor, found it has split into 2 projects, so I replaced my dependencies like this:

-    //https://bintray.com/bintray/jcenter/org.jooq%3Ajoor
-    //https://github.com/jOOQ/jOOR
-    api 'org.jooq:joor:0.9.7'
+    // https://mvnrepository.com/artifact/org.jooq/joor-java-8
+    api group: 'org.jooq', name: 'joor-java-8', version: '0.9.7'

Clean and build, and it now passes.

I had that issue when moved to Android Studio 3.0

Ensure that you have same versions of firebase-core and play-services, e.g.:

 compile 'com.google.android.gms:play-services-ads:11.0.4'
 compile 'com.google.firebase:firebase-core:11.0.4'
