Why Isn\'t IntelliJ IDEA Detecting My Java Errors?

Debugging Auto Error Detection in IntelliJ IDEA

For novice developers utilizing IntelliJ IDEA 2017.1, encountering challenges with the IDE's auto error detection can be frustrating. Despite activating various inspections, errors such as missing brackets and semicolons remain undetected.

This issue arises when the Java file containing the code is located outside of the project's designated Source Root. To resolve this, follow these steps:

1. Relocate the File: Move the Java file into a folder within the project's source root. This folder will typically be marked in blue in the project view, with a different class icon than files located outside of it.
2. Reconfigure Content Roots: If relocating the file is not feasible, you can reconfigure your project's content roots. In the Project View, right-click on the project root and select "Content Roots." Add the appropriate folder as a new content root.

After completing one of these steps, IntelliJ IDEA will analyze the Java file properly and identify errors. This will ensure timely detection and resolution of coding mistakes, enhancing your development workflow and code quality.
