If you are a first-time contributor looking for features to implement or bugs to fix, see the issues tagged with 'candidate' in the Mindustry-Suggestions repostiory.

Bleeding-edge builds are generated automatically for every commit. You can see them here.

If you'd rather compile on your own, follow these instructions. First, make sure you have JDK 17 installed. Other JDK versions will not work. Open a terminal in the Mindustry directory and run the following commands:

Running: gradlew desktop:run
Building: gradlew desktop:dist
Sprite Packing: gradlew tools:pack

Running: ./gradlew desktop:run
Building: ./gradlew desktop:dist
Sprite Packing: ./gradlew tools:pack

Server builds are bundled with each released build (in Releases). If you'd rather compile on your own, replace 'desktop' with 'server', e.g. gradlew server:dist.

1. Install the Android SDK here. Make sure you're downloading the "Command line tools only", as Android Studio is not required.
2. In the unzipped Android SDK folder, find the cmdline-tools directory. Then create a folder inside of it called latest and put all of its contents into the newly created folder.
3. In the same directory run the command sdkmanager --licenses (or ./sdkmanager --licenses if on linux/mac)
4. Set the ANDROID_HOME environment variable to point to your unzipped Android SDK directory.
5. Enable developer mode on your device/emulator. If you are on testing on a phone you can follow these instructions, otherwise you need to google how to enable your emulator's developer mode specifically.
6. Run gradlew android:assembleDebug (or ./gradlew if on linux/mac). This will create an unsigned APK in android/build/outputs/apk.

To debug the application on a connected device/emulator, run gradlew android:installDebug android:run.

If the terminal returns Permission denied or Command not found on Mac/Linux, run chmod +x ./gradlew before running ./gradlew. This is a one-time procedure.

As the name implies, mindustry.gen is generated at build time based on other code. You will not find source code for this package in the repository, and it should not be edited by hand.

The following is a non-exhaustive list of the "source" of generated code in mindustry.gen:

• Call, *Packet classes: Generated from methods marked with @Remote.
• All entity classes (Unit, EffectState, Posc, etc): Generated from component classes in the mindustry.entities.comp package, and combined using definitions in mindustry.content.UnitTypes.
• Sounds, Musics, Tex, Icon, etc: Generated based on files in the respective asset folders.

Gradle may take up to several minutes to download files. Be patient.
After building, the output .JAR file should be in /desktop/build/libs/Mindustry.jar for desktop builds, and in /server/build/libs/server-release.jar for server builds.
