Question
What are the steps to create a 'java' folder in a Maven web application project using IntelliJ IDEA?
Answer
Creating a 'java' folder in a Maven web application project in IntelliJ IDEA is a straightforward process that helps organize your Java source files. This guide outlines the necessary steps to ensure your folder structure aligns with the Maven standard.
Causes
- You might be starting a new Maven project and need to establish the correct directory structure.
- You may be adding new components or re-organizing the source code within your existing Maven project.
Solutions
- 1. Open your Maven web application project in IntelliJ IDEA. 2. In the Project tool window (usually found on the left side), navigate to the `src` folder. 3. Right-click on the `src` folder, hover over `New`, and then select `Directory`. 4. Name the new directory exactly as 'java'. 5. Ensure that this folder is marked as a source root by right-clicking it and selecting 'Mark Directory as' -> 'Sources Root'. 6. After that, you can start adding your Java classes inside this folder.
Common Mistakes
Mistake: Not marking the 'java' folder as a source root.
Solution: Make sure to right-click the 'java' folder after creating it and select 'Mark Directory as' -> 'Sources Root'.
Mistake: Creating the 'java' folder at the wrong level in the directory structure.
Solution: Always create it inside the `src` folder of your Maven project to maintain the standard structure.
