If you need to use D8 as a dependency in a build system like Maven or Gradle, you can find the artifact (which includes D8) at maven.google.com under the group com.android.tools:r8 Build from Source
In the rapidly evolving world of Android development, optimization is key. As apps become more complex, the need for efficient, fast, and compact bytecode becomes crucial. Enter , Android’s modern DEX compiler that has replaced the traditional Dx tool.

file; it is distributed as part of the Android SDK and the open-source R8 project. Stack Overflow Android SDK (Standard Path): If you have the Android SDK installed, is located in your build tools directory: android_sdk/build-tools/ /lib/d8.jar ~/Android/Sdk/build-tools/29.0.3/lib/d8.jar Google Maven Repository: D8 classes are bundled in the com.android.tools:r8 artifact available at maven.google.com Prebuilt CI Artifacts:
If you’ve ever worked with Android’s build tools, you’ve likely encountered d8 — the successor to the legacy dx compiler. d8.jar is the executable JAR file that contains Google’s DEX compiler, responsible for converting Java bytecode ( .class files) into Dalvik Executable ( .dex ) format, which runs on Android devices.
By pulling d8.jar directly through Google's Android SDK manager, you guarantee that your environment utilizes a secure, stable, and highly-optimized compiler built for modern Android architectures. By pulling d8

It is faster than dx and creates smaller DEX files, contributing to smaller APK sizes.
Interestingly, Google packages both tools inside the same underlying codebase. When you download modern versions of Android Build Tools, d8.jar frequently functions as an entry point to the larger R8 library, but optimized specifically to run in D8 compilation mode. Best Practices and Safety Tips contributing to smaller APK sizes.
