Enable auto format on save

  • IntelliJ

    Automatically reformat code on save

    1. File > Settings > Tools > Actions on Save

    2. Enable any desired options, e.g.

      • Reformat code
      • Optimize imports

    3. Disable formatting properties files

      (It doesn’t seem to do anything except annoyingly remove blank lines, which can be useful to group properties)

      Reformat code > All file types > uncheck Properties

  • Android Studio: Auto format code in Android Studio/Intellij IDEA

Enable automatic update when Gradle config is changed

  1. File > Settings > Build, Execution, Deployment > Build Tools

  2. Make sure Reload project after changes in the build scripts is checked

  3. Select Any changes > OK

Disable spell checking

Disable auto saving

ⓘ IntelliJ will auto save when you switch to another application, but this may trigger a lengthy rebuild in some projects and may be undesirable

  1. File > Settings > Appearance & Behavior > System Settings

  2. Uncheck Save files when switching to a different application or a built-in terminal
