version used in your project and applies the corresponding Java version. However, you can manually override the Java version if needed. ## Automatic Java Version Detection[ΒΆ](#automatic-java-version-detection "Permanent link") Capawesome Cloud supports Gradle Plugin Version 8.0.0 and higher. The Java version is automatically selected based on your Android Gradle Plugin version: | Android Gradle Plugin | Java Version | | --------------------- | ------------ | | 8.0.0 - 8.7.1 | 17 | | \>= 8.7.2 | 21 | This automatic detection ensures your builds use the appropriate Java version without additional configuration. ## Override Java Version[ΒΆ](#override-java-version "Permanent link") To override the automatic Java version selection, set the `JAVA_VERSION` environment variable: 1. Navigate to the [Environments](https://console.cloud.capawesome.io/apps/%5F/environments) page 2. Select your environment or create a new one 3. Add a variable named `JAVA_VERSION` 4. Set its value to the major version number (e.g., `17` or `21`) Version constraints The `JAVA_VERSION` environment variable must be set to an integer representing the major version, such as `17` or `21`. For available Java versions, refer to the [Build Stacks](/docs/cloud/native-builds/build-stacks/) documentation. ## Example[ΒΆ](#example "Permanent link") To use Java 17 for your Android builds regardless of your Gradle Plugin version: 1. Add an environment variable named `JAVA_VERSION` with the value `17` 2. Select this environment when triggering your build The specified Java version will be used instead of the automatically detected version. May 7, 2026 Back to top
