```bash
# Compile the source code
mvn compile

# Build JAR file
mvn package

# Clean and rebuild
mvn clean compile

# Install to local repository
mvn install
```

### Testing
```bash
# Run all tests (JUnit 4 based)
mvn test

# Run specific test class
mvn test -Dtest=SpecificTest

# Alternative test runner
mvn surefire:test
```

### Code Quality

```bash
# Build all modules
mvn clean install

# Build without tests
mvn clean install -DskipTests

# Build specific module
mvn clean install -pl fess-crawler

# Generate test coverage report
mvn jacoco:report
```

### Code Quality

```bash
# Format code
mvn formatter:format

# Update license headers
mvn license:format

# Run static analysis

    $ 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 -Dparallel=classes -DthreadCount=4 -DforkCount=1C -DreuseForks=true
    - name: Run Fess

## Development Workflow

### Build Commands

```bash
mvn clean install              # Build all
mvn clean install -DskipTests  # Skip tests
mvn test                       # Run tests
mvn formatter:format           # Format code
mvn license:format             # Update license headers
```

### Code Style

 -----

Maven 4 API - CLI

 This is the {{{./apidocs/org/apache/maven/api/cli/package-summary.html}API}} for Maven's command-line interface and
 tools:

   * <<<{{{./apidocs/org/apache/maven/api/cli/mvn/package-summary.html}mvn}}>>>, the Maven build tool,

   * <<<{{{./apidocs/org/apache/maven/api/cli/mvnenc/package-summary.html}mvnenc}}>>>, the Maven Password Encryption tool,

## Development Workflow

### Build Commands

```bash
mvn compile                              # Compile
mvn test                                 # Run all tests
mvn test -Dtest=SuggesterTest           # Run specific test
mvn package                              # Package JAR
mvn formatter:format license:format     # Format code and apply licenses
mvn clean jacoco:prepare-agent test jacoco:report  # Generate coverage report
```

# 4. Update configuration (ensure 'sv' is in supported.languages)
# Edit fess_config.properties line 202

# 5. Regenerate Java classes
cd ../../../..
mvn dbflute:freegen

# 6. Rebuild project
mvn clean package

# 7. Test
# Run org.codelibs.fess.FessBoot
# Access: http://localhost:8080/admin/?browser_lang=sv
```

## Troubleshooting

   per project settings can be defined by files in <<<.mvn/>>> directory:

   * <<<.mvn/jvm.config>>> containing jvm options,

   * <<<.mvn/maven.config>>> containing Maven command-line parameter,

   * <<<.mvn/extensions.xml>>> containing {{{./core-extensions.html}a list of extensions}},

 * KIND, either express or implied.  See the License for the
 * specific language governing permissions and limitations
 * under the License.
