How to create a simple Eclipse Code Formatter for IntelliJ IDEA and Eclipse IDE?

What is Code Formatter?

The Eclipse Code Formatter is a feature of the Eclipse Integrated Development Environment (IDE) that helps developers maintain consistent code formatting and style across their projects. It automates the process of formatting code according to predefined rules and conventions.

The Eclipse Code Formatter allows developers to define a set of formatting rules that specify how the code should be organized, including indentation, line breaks, spacing, and other stylistic elements. These rules can be configured to match specific coding standards or project guidelines.

Here are some key features and benefits of the Eclipse Code Formatter:

1. Consistent Code Style: By applying the code formatter, developers can ensure that the code within their projects adheres to a consistent style, making it easier for team members to read, understand, and maintain the codebase.
2. Customizable Formatting Rules: Eclipse provides a rich set of options to customize the formatting rules to match specific preferences or coding standards. Developers can configure various aspects such as indentation size, line wrapping policies, naming conventions, and much more.
3. Automatic Formatting: The Eclipse Code Formatter can automatically format code as developers write or edit it. This saves time and effort, as developers don’t have to manually adjust code indentation or spacing.
4. Batch Formatting: Developers can also format existing code files in bulk using the code formatter. This is particularly useful when working on projects with legacy code or when enforcing formatting standards on a large codebase.
5. Integration with IDE: The Eclipse Code Formatter seamlessly integrates with the Eclipse IDE, allowing developers to format code directly from the code editor or through specific menu options. It provides instant visual feedback on the formatted code, making it easy to review and adjust as needed.

Using the Eclipse Code Formatter helps promote code consistency, readability, and maintainability within development projects. It simplifies the process of adhering to coding standards and enhances collaboration among team members by reducing formatting discrepancies.

See below the eclipse code formatter that I customized based on the recent project needs and is more compliant to the recent coding standard. Just copy and paste this into your project and save it as a xml file and target it through the eclipse code formatter plugin in IntelliJ.
Note : This can be used in Eclipse IDE as well.
