What happened?

The project fails to load in Android Studio (latest stable release 2024.3.1):

Multiple build operations failed.
    Could not create task ':core:data:compileDebugAndroidTestJavaWithJavac'.
    Could not create task ':core:data-testing:compileDebugAndroidTestJavaWithJavac'.
    Could not create task ':core:designsystem:compileDebugAndroidTestJavaWithJavac'.
    Could not create task ':mobile:compileDebugAndroidTestJavaWithJavac'.
Could not create task ':core:data:compileDebugAndroidTestJavaWithJavac'.
Failed to calculate the value of task ':core:data:compileDebugAndroidTestJavaWithJavac' property 'javaCompiler'.
Cannot find a Java installation on your machine matching this tasks requirements: {languageVersion=17, vendor=any vendor, implementation=vendor-specific} for MAC_OS on aarch64.
No locally installed toolchains match and toolchain download repositories have not been configured.

I reported a similar issue with tv-samples JetStream back in October. https://github.com/android/tv-samples/issues/192 This works for me, (although not sure about the github actions yml)

git grep -l JDK | xargs sed -i 's/JDK 17/JDK 21/g'
git grep -l java-version | xargs sed -i 's/java-version: 17/java-version: 21/g'
git grep -l jvmToolchain | xargs sed -i 's/jvmToolchain(17)/jvmToolchain(21)/g'
git grep -l jvmTarget | xargs sed -i 's/jvmTarget = "17"/jvmTarget = "21"/g'
git grep -l JavaVersion | xargs sed -i 's/JavaVersion.VERSION_17/JavaVersion.VERSION_21/g'

I'm not doing a pull request, because I don't know enough about why this was hardcoded to java 17 in the first place. Maybe I'm missing something.

Did you try re-cloning the project? I've just clone and the project built

[gramound]

Re-cloning didn't help for me unfortunately.

Did you install your own java 17? I thought Android Studio used its own from:

% /Applications/Android\ Studio.app/Contents/jbr/Contents/Home/bin/javac -version
javac 21.0.5

Have you tried opening each project alone and not the entire project file?

[kaamel]

I have the same issue.

Have you tried opening each project alone and not the entire project file?

Yes, that is what I do. I clone the repo outside of Android Studio and open each project alone in a new window.

I think I figured it out by comparing with other projects:

In core:data, core:data-testing, core:designsystem and mobile

Replace this (in build.gradle.kts):

kotlin {
    jvmToolchain(17)
}

By this (inside the android { ... } section):

    kotlinOptions {
        jvmTarget = "17"
    }

[gramound]

Seems related to #1526

[luciferChou]

replace kotlin { jvmToolchain(17) } with kotlinOptions { jvmTarget = "17" } in build.gradle.kts files. it worked,ths

[Sarthak7Gautam]

I was using the old version of Android Studio so it did not work, installed the latest version and it started working
