```bash
# Clean build and run tests
mvn clean test

# Full build with packaging
mvn clean package

# Run tests only
mvn test

# Run specific tests
mvn test -Dtest=CurlTest
mvn test -Dtest=CurlRequestTest
mvn test -Dtest=CurlResponseTest
mvn test -Dtest=CurlExceptionTest
```

### Code Quality
```bash
# Format code (using external formatter config)
mvn formatter:format

# Check license headers

# Download OpenSearch plugins (required before first build)
mvn antrun:run

# Generate DBFlute source code (when schema changes)
mvn dbflute:download  # One-time setup
mvn dbflute:freegen
mvn license:format
```

### Build
```bash
# Standard build
mvn package

# Clean build
mvn clean package

# Build distribution packages
mvn rpm:rpm          # .rpm package
mvn jdeb:jdeb        # .deb package
```

### Testing

    $ mvn dbflute:freegen
    $ mvn license:format

### Integration Tests

Integration tests require a running Fess server with OpenSearch. Follow these steps:

#### 1. Build Fess

    $ mvn antrun:run  # Download OpenSearch plugins (if not done)
    $ mvn package     # Build the package

#### 2. Start Fess Server

    $ unzip target/releases/fess-*.zip

        ref: ${{ env.PARENT_BRANCH }}
        path: fess-parent
    - name: Install fess-parent
      run: |
        cd fess-parent
        mvn install -Dgpg.skip=true
    - name: Download Plugins with Maven
      run: mvn -B antrun:run --file pom.xml
    - name: Build with Maven
      run: mvn -B source:jar javadoc:jar package --file pom.xml
    - name: Run Fess
      run: bash src/test/resources/before_script.sh
