### Development Setup

```bash
# Clone the repository
git clone https://github.com/codelibs/fess-crawler.git
cd fess-crawler

# Build the project
mvn clean install

# Run tests
mvn test

# Format code before committing
mvn formatter:format

import org.jspecify.annotations.Nullable;

@GwtCompatible

  static boolean equal(@Nullable Object a, @Nullable Object b) {
    return a == b || (a != null && a.equals(b));

 delegating content to {{{../../api/maven-api-settings/index.html}Maven 4 API immutable settings}}. All the effective model
 building logic from multiple settings files is done in {{{../maven-settings-builder/}Maven Settings Builder}}.

 The following are generated from this model:

		format := newFormatErasureV3(setCount, setDriveCount)
		format.ID = deploymentID
		for i := range setCount { // for each erasure set
			for j := range setDriveCount {
				newFormat := format.Clone()
				newFormat.Erasure.This = format.Erasure.Sets[i][j]
				if deploymentID != "" {
					newFormat.ID = deploymentID
				}
				drive := pool.Endpoints[i*setDriveCount+j]
				fmtBytes, err := json.Marshal(newFormat)
