## Contributing

We welcome contributions to Fess Crawler! Please follow these guidelines:

1. **Fork** the repository
2. **Create** a feature branch (`git checkout -b feature/amazing-feature`)
3. **Commit** your changes (`git commit -m 'Add amazing feature'`)
4. **Push** to the branch (`git push origin feature/amazing-feature`)
5. **Open** a Pull Request

### Development Setup

```bash
# Clone the repository

        // Newline characters
        testTransformer.setName("name\nwith\nnewlines");
        assertEquals("name\nwith\nnewlines", testTransformer.getName());
    }

    /**
     * Test multiple name changes
     */
    public void test_multipleNameChanges() {
        String[] names = { "first", "second", "third", "fourth", "fifth" };

        for (String name : names) {
            testTransformer.setName(name);

        assertSame(processor1, registeredRule.getResponseProcessor());

        // Change properties after registration
        TestResponseProcessor processor2 = new TestResponseProcessor();
        testRule.setRuleId("changedId");
        testRule.setResponseProcessor(processor2);

        // Verify changes are reflected (same object reference)
        assertEquals("changedId", registeredRule.getRuleId());

3. Follow coding standards: `mvn formatter:format`
4. Add tests for new functionality
5. Ensure all tests pass: `mvn test`
6. Check license headers: `mvn license:format`
7. Commit changes: `git commit -m 'Add amazing feature'`
8. Push to branch: `git push origin feature/amazing-feature`
9. Open a Pull Request
