Causes of Gradle Task AssembleDebug Exit Code 1
The Gradle Task AssembleDebug exit code 1 error may be caused by various factors, including:
- Outdated Gradle or Android Studio versions
- Dependency conflicts
- Incorrect signing configurations
- Corrupted Gradle cache
- Misconfigured JAVA_HOME or JDK path
Solution 1: Update Gradle and Android Studio
Ensure that you are using the latest versions of Gradle and Android Studio. Outdated versions may cause compatibility issues and lead to errors during the build process.
Update Gradle
- Open your project's
build.gradle
file. - Update the Gradle version in the
dependencies
block:
dependencies {
classpath 'com.android.tools.build:gradle:4.2.2' // Update to the latest version
}
- Sync the project to apply the changes.
Update Android Studio
- Open Android Studio.
- Go to Help > Check for Updates (Windows/Linux) or Android Studio > Check for Updates (macOS).
- Follow the prompts to update Android Studio if a new version is available.
Solution 2: Resolve Dependency Conflicts
Dependency conflicts can cause the Gradle Task AssembleDebug exit code 1 error. Check your project's build.gradle
file for conflicting dependencies and resolve them.
- Open your project's
build.gradle
file. - Check for duplicate or conflicting dependencies in the
dependencies
block. - Remove or update the conflicting dependencies to resolve the issue.
- Sync the project to apply the changes.
Solution 3: Check Signing Configurations
Incorrect signing configurations in your project's build.gradle
file may lead to the Gradle Task AssembleDebug exit code 1 error. Ensure that the signing configurations are set up correctly.
- Open your project's
build.gradle
file. - Check the
android
block for thesigningConfigs
section. - Ensure that the signing configurations are set up correctly, including the correct file paths and passwords.
android {
...
signingConfigs {
release {
storeFile file("path/to/keystore")
storePassword "your_store_password"
keyAlias "your_key_alias"
keyPassword "your_key_password"
}
}
...
}
- Sync the project to apply the changes.
Solution 4: Clear Gradle Cache
Corrupted Gradle cache files may cause the Gradle Task AssembleDebug exit code 1 error. Clearing the cache can resolve this issue.
Close Android Studio.
Delete the .gradle
folder in your project directory.
Delete the caches
folder in the Gradle user home directory:
- Windows:
%USERPROFILE%\.gradle\caches
- macOS:
~/.gradle/caches
- Linux:
~/.gradle/caches
Restart Android Studio and sync the project.
Solution 5: Configure JAVA_HOME and JDK Path
Misconfigured JAVA_HOME or JDK path settings may cause the Gradle Task AssembleDebug exit code 1 error. Ensure that these settings are configured correctly.
Verify the JAVA_HOME environment variable:
- Windows: Open the Environment Variables window and check the
JAVA_HOME
variable. - macOS/Linux: Run
echo $JAVA_HOME
in the terminal.
Ensure that the JDK path in Android Studio is set correctly:
- Go to File > Project Structure > SDK Location.
- Verify that the JDK location is set to the correct path.
Sync the project to apply the changes.
FAQs
1. How do I find the exact error message for the Gradle Task AssembleDebug exit code 1 error?
To find the exact error message, open the Build output tab in Android Studio or run ./gradlew assembleDebug --stacktrace
in the terminal.
2. How can I check for updates to Gradle and Android Studio automatically?
Android Studio periodically checks for updates and notifies you when new versions are available. You can also configure the update settings in Settings > Appearance & Behavior > System Settings > Updates.
3. How do I check my Gradle and Android Studio versions?
You can check the Gradle version in your project's build.gradle
file and the Android Studio version in Help > About (Windows/Linux) or Android Studio > About Android Studio (macOS).
4. How do I resolve dependency conflicts in my project?
To resolve dependency conflicts, remove or update the conflicting dependencies in your project's build.gradle
file. You can also use the resolutionStrategy
block to force specific versions of conflicting dependencies.
5. How do I set up the JAVA_HOME environment variable?
To set up the JAVA_HOME environment variable, follow these steps:
- Windows: Open the Environment Variables window and create a new variable named
JAVA_HOME
