Boost Your Java Productivity: 15 Essential IntelliJ IDEA Plugins & Tips

1. Install Plugins

Codota – AI‑powered code completion

Type a few letters and Codota suggests full statements, showing usage frequency based on your project’s code patterns.

Key Promoter X – Shortcut hints

Displays a popup with the corresponding shortcut whenever you use a menu action, helping you memorize key bindings quickly.

CodeGlance – Code minimap

Shows a thumbnail overview of the entire file on the right side, making navigation in large files much easier.

Lombok – Reduce boilerplate

Automatically generates getters, setters, constructors, toString, hashCode, and other common methods, keeping your code concise.

Alibaba Java Coding Guidelines – Code style inspection

Checks your code against Alibaba’s Java standards, highlights violations with colored hints, and offers quick fixes.

CamelCase – Naming conversion

Switches between camelCase and snake_case with Shift+Alt+U, useful for bulk renaming.

MybatisX – MyBatis productivity

Provides code assistance, mapper navigation, and SQL preview for MyBatis projects.

SonarLint – Real‑time code quality

Detects bugs, code smells, and security issues on the fly, recommending logger usage over System.out.

Save Actions – Automatic code cleanup

Optimizes imports, adds final to unused variables, inserts this where appropriate, and enforces consistent formatting.

CheckStyle – Style enforcement

Similar to Alibaba’s guidelines, it checks Java code against configurable style rules.

Grep Console – Custom console output

Allows you to color‑code and format console logs for better readability.

MetricsReloaded – Complexity analysis

Shows cyclomatic complexity, maintainability index, and other metrics directly in the IDE.

Statistic – Code statistics

Provides quick counts of lines, classes, methods, and other code statistics.

Translation – Inline translation

Translates selected text directly within the editor.

Rainbow Brackets – Colorful brackets

Displays matching brackets in the same color, making nested structures easier to read.

2. Create Live Templates for Faster Coding

Define abbreviations (e.g., typing apr expands to @Autowired) to generate common code snippets instantly.

3. Global Settings to Boost Efficiency

Optimize import settings

Show tabs in multi‑line mode

Allows more files to be visible simultaneously.

Move line comments to the code start

Copy whole line on selection

Enables copying an entire line even if only part of it is selected.

Disable case‑sensitive matching

After unchecking, typing a lowercase s still suggests String.

Improve VCS directory color scheme

Auto‑insert author and timestamp on new files

Show line numbers and method separators
