👨‍💻 Setup a development environment for ReVanced

A certain development environment is suggested to allow for streamlined development on ReVanced.

1. ⬇️ Clone necessary repositories

repositories=(
    "revanced-cli"
    "revanced-patches"
    "revanced-patcher" # optional
    "revanced-integrations"
)

for repository in "${repositories[@]}" ; do
        git clone -b dev --single-branch --depth 1 https://github.com/revanced/$repository
done

2. 🛠️ Build from source

Before building you need to be authenticated to GitHub Packages. This will assume you have a GitHub account

Create a PAT with the scope read:packages here and add your token to ~/.gradle/gradle.properties.

Example gradle.properties file:

gpr.user = ReVanced
gpr.key = ghp_key

To build all projects, run the following command from the directory which contains the repositories

repositories=(
    "revanced-cli"
    "revanced-patches"
    "revanced-patcher" # optional
    "revanced-integrations"
)

for repository in "${repositories[@]}" ; do
        cd $repository
        ./gradlew build
        cd ..
done

3. ⚙️ Setup IntelliJ IDEA

Open the revanced-cli project in IntelliJ IDEA and ensure you are using the right JDK from 💼 Prerequisites
Import the revanced-patches and optionally the revanced-patcher project as modules into the revanced-cli project

Add a new Run/Debug configuration for the revanced-cli project; Make sure to add Before launch tasks to build revanced-patches and optionally publish revanced-patcher

Example configuration:

 <component name="ProjectRunConfigurationManager">
     <configuration default="false" name="Run ReVanced CLI" type="JetRunConfigurationType">
         <option name="MAIN_CLASS_NAME" value="app.revanced.cli.main.MainKt" />
         <module name="revanced-cli.main" />
         <option name="PROGRAM_PARAMETERS" value="
             --options ../options.toml
             -o ../revanced.apk
             -a ../binaries/unpatched-input.apk
             -t ../revanced-cache
             -b ../revanced-patches/build/libs/revanced-patches-<version>.jar
             -m ../revanced-integrations/app/build/outputs/apk/release/revanced-integrations-<version>.apk
             -d device-name"
         />
         <method v="2">
             <option name="RunConfigurationTask" enabled="true" run_configuration_name="revanced-patcher [publish]" run_configuration_type="GradleRunConfiguration" />
             <option name="RunConfigurationTask" enabled="true" run_configuration_name="revanced-patches [build]" run_configuration_type="GradleRunConfiguration" />
             <option name="Make" enabled="true" />
         </method>
     </configuration>
 </component>

Note: The build file names of revanced-patches and revanced-integrations change. Do not forget to update them in the run configuration program arguments.

4. ⚙️ Setup Android Studio

Open the revanced-integrations project in Android Studio and ensure you are using the latest Android SDK.
Add a new default build configuration and confirm if it succeeds.

5. ⚠️ Troubleshoot your development environment

To confirm your development environment works as intended, set a breakpoint in any patch from the revanced-patches project in IntelliJ IDEA. Run the build configuration for revanced-cli and confirm that your IDE reaches and breaks at the breakpoint. Continue and let ReVanced CLI exit.

If ReVanced CLI output is unexpected, confirm if you supplied the correct program arguments by following 💻 ReVanced CLI.
If the breakpoint was not hit, confirm that you correctly added the necessary projects as modules to the revanced-cli project

❗ Afterword

A couple of things should be considered with the development environment for ReVanced:

Follow conventional commits
Pull new commits from remote to keep your branch up to date
Keep your Run/Debug configuration up to date. After pulling new commits, ensure you use the correct paths in your program argument. If you forget to do this, you might end up debugging for hours until realising, you supply the wrong paths to ReVanced CLI
Use development branches and always branch off and PR to dev branches
To use the local revanced-patcher project in the revanced-cli and revanced-patches projects, make sure you publish it to the local Maven repository with ./gradlew publish and use the correct version in the build.gradle.kts file in the revanced-cli and revanced-patches projects, otherwise, it will use the package from GitHub Packages
