Gradle 8.0 build issue

[alexmirash]

Cause: superclass access check failed: class butterknife.compiler.ButterKnifeProcessor$RScanner (in unnamed module @0x69d73d) cannot access class com.sun.tools.javac.tree.TreeScanner (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.tree to unnamed module @0x69d73d

same problem but gradle 8.0 isn't the reason, 7.2.2 - still appears appeared after update on Android Studio to Flamingo

@jorrrdane I agree as well. It seems to be related to Flamingo upgrade. I just upgraded and run into this problem (Linux).

When I saw errors like this in the past, eventually they were related to the proguard. But in my case, I am building debug, so proguard should not even be in the picture

I have upgraded a toy project to AGP 8.0 through a few walkarounds below

go to Android Studio Preferences..., then Build, Execution, Deployment / Build Tools / Gradle, then set the Gradle JDK to be of some version 15

can't. when use gradle 8, JDK version 17 at least

[wujun2081]

go to Android Studio Preferences..., then Build, Execution, Deployment / Build Tools / Gradle, then set the Gradle JDK to be of some version 15

Tested and effective

[mrfaa]

Faced the same issue. With this seetings it is working for me:

gradle-wrapper.properties:

build.gradle (app):

build.gradle (project) dependencies:

JDK is 17.

[savelyevdm]

go to Android Studio Preferences..., then Build, Execution, Deployment / Build Tools / Gradle, then set the Gradle JDK to be of some version 15

Fix works if your gradle version is still under 8.0 (as it requires JDK 17 minimium).

[savelyevdm]

@JakeWharton If the library is discontinued in support - should we even hope for the update to support JDK 17 ?

[VectorWen]

use JDK15 can fixed.

[ShaFaisal]

its working thanks lot

[QODOHUB]

use JDK15 can fixed. this fix is not work

[eurigo]

The default JDK version of Android Studio Flamingo is 17 , which will cause the compilation to fail.

Solution:

1. Install OpenJDK 11 or JDK 11
2. Modify the default JDK version of Android Studio

   Settings --> Gradle --> Gradle JDK:(set your install JDK)

[payne1107]

use JDK15 can fixed. this fix is not work are you sure？

[nehal-gohil]

Use Gradle JDK 11 version from settings search gradle and select JDK version 11, Works for me

[dineshrajamanikam]

Use JDK Version 11.0.19 actual version but use around 11 versions. it'll work.

[jdaccusys]

Hello! I used this on my build.gradle(app)

    kotlin {
        kotlinOptions {
            jvmTarget = "1.8"
        }
    }

https://www.oracle.com/pk/java/technologies/javase/jdk11-archive-downloads.html
Download JDK 11 for your desired OS
Install it
Android Studio-> File -> Project Structure -> SDK Location -> Click on Gradle Settings (blue hightlighted text) -> Select the jdk 11 with 11.0 something version name from list
Run The Project
Boom! it's works

Or migrate to viewBinding

same problem, Please don't deprecate this lib. Although there is view binding, this lib are still better than view binding. eg.eliminating anonymous inner-classes for listeners by annotating methods with @OnClick and others.
