Build Apktool

Apktool is a project that contains a collection of subprojects and dependencies.

  • brut.apktool.lib - Main Library
  • brut.apktool.cli - CLI Interface
  • brut.j.dir - Utility
  • brut.j.util - Utility
  • brut.j.common - Utility


Build Steps

First clone the repository using either: SSH or HTTPS.

  1. Navigate to the Apktool folder and for the remaining steps use ./gradlew for Unix based systems or gradlew.bat for Windows.
  2. You can build the project in two ways:

v2.10 moved from Proguard to R8, but kept the naming to Proguard for the time being. This will be updated in the future.

Without R8 (JDK > 8)

[./gradlew][gradlew.bat] build shadowJar
  • Creating a jar file: brut.apktool/apktool-cli/build/libs/apktool-cli-all.jar.

With R8 (JDK > 11):

[./gradlew][gradlew.bat] build shadowJar proguard
  • Creating a jar file: brut.apktool/apktool-cli/build/libs/apktool-vXXX.jar.

Windows Requirements


Be aware of directory path length limitations on Windows.

Windows has some limitations regarding max filepath. At one location in Apktool, we have a 218 character directory path which means due to the limitation of max 255 characters on Windows we need to enforce some requirements.

This leaves 37 characters total to clone the project on Windows. For example, I can clone this project to the location


This is 31 characters, which allows Apktool to be cloned properly. Cloning the project into a directory longer than 37 characters will not work.
