-Code formatting is enforced using the [Spotless](https://github.com/diffplug/spotless)

+Code formatting is automatically enforced using the [Spotless](https://github.com/diffplug/spotless) Gradle plugin during the build process. The build will:
+
+- Automatically format all code
+- Add missing license headers
+- Correct import order
+- Fix other style issues
+
+You can run the plugin goal `gradle spotlessApply` to apply formation.
+Nevertheless, that´s not required, as the build handles everything automatically.
+
+IDE configuration is available for consistency:
+- **Eclipse**: Use our predefined settings:
+  - [Formatter config](gradle/config/eclipse/junit-eclipse-formatter-settings.xml)
+  - [Import order](gradle/config/eclipse/junit-eclipse.importorder)
+- **IntelliJ**: Install the [Eclipse Code Formatter plugin](https://plugins.jetbrains.com/plugin/6546) with our settings
+
+**Important**: Wildcard imports (e.g., `import static org.junit.jupiter.api.Assertions.*;`) remain strictly forbidden.
+
+**Usage requirements:**
+1. Both `CI` and `rewriteRun` environment variables must be set:
+- `CI=false` to enable execution
+- `spotlessApply=true` to auto-apply suggestions
+2. Dry runs execute by default for change preview
+3. Changes are blocked in CI environments (when `CI=true`)
+4. Always review changes before applying
+
+just add this to your shell config:  ~/.zshrc
+export spotlessApply=true
+export rewriteRun=true
+
+#### Rewriting
+
+The build supports automated code refactoring through [Moderne](https://moderne.io/) rewrite rules. These transformations are controlled exclusively through environment variables - there is no local variable configuration option to apply automatic fixes out of the box.
