Migrate to Gradle Daemon Toolchain

[dfabulich]

When I open a fresh Skip project in the latest Android Studio Panda 1 | 2025.3.1 Patch 1, after Gradle sync, it prompts me to "Migrate to Gradle Daemon toolchain"

Migrate to Gradle Daemon toolchain

Projects using Daemon toolchain allow builds to automatically detect installed toolchains given the defined JVM criteria or download a compatible one if cannot be found locally. In addition, using the Daemon toolchain aligns the selection between CLI and IDE, avoiding spawning multiple Daemons improving performance but also makes it simple to handle the required toolchain on different machines.

The "Learn More" link points to https://docs.gradle.org/current/userguide/gradle_daemon.html#daemon_jvm_criteria but I think they meant to link to this section: https://docs.gradle.org/current/userguide/gradle_daemon.html#sec:configuring_daemon_jvm

If you click "Migrate", it adds a foojay-resolver-convention plugin to settings.gradle.kts and runs:

Executing tasks: [updateDaemonJvm, --jvm-version, 21, --jvm-vendor, jetbrains] in project /private/tmp/tp/project-name/Android

That creates an Android/gradle/gradle-daemon-jvm.properties file, like this:

That seems to be all it does.

I think we would need gradlew to make this useful.

• Explore using gradlew #600

After migrating, when I quit Android Studio, run gradle --stop and gradle -p Android assembleDebug, it downloads a copy of the Jetbrains JDK into ~/.gradle/jdks/jetbrains_s_r_o_-21-aarch64-os_x.2/jbrsdk_jcef-21.0.10-osx-aarch64-b1163.105/Contents/Home/bin/java.

But gradle is my Homebrew gradle, which doesn't happen to match the version of Gradle provided by Android Studio, so they refuse to share a Gradle daemon.

It does work if I manually setup a gradlew and gradle/wrapper/gradle-wrapper.jar and then ./gradlew --stop and ./gradlew assembleDebug. Then, the IDE and the CLI agree to use the same version of Gradle, sharing a daemon. Android Studio is even willing to share the daemon launched from the CLI, without starting its own copy with its own JDK.
