Confgure IntelliJ to use the same Java formatter as Spotless

Question

I use the Spotless Gradle plugin to ensure consistent formatting of the Java code in my app. The relevant entries in build.gradle are

plugins {
  id "com.diffplug.gradle.spotless" version "3.27.0"
}

spotless {
  java {
    // The available versions of the Eclipse JDT formatter are defined here
    // https://github.com/diffplug/spotless/tree/master/lib-extra/src/main/resources/com/diffplug/spotless/extra/eclipse_jdt_formatter
    eclipse('4.13.0')
    indentWithSpaces()
    removeUnusedImports()
  }
}

Is there some way I can configure IntelliJ to use the same formatting settings?

Answer 1

A not 100% satisfying but working approach:

1. Configure the Spotless tasks

spotless {
    format 'misc', {
        target '*.properties','*.gradle', '*.md', '.gitignore' // etc.
        // code style rules
    }
    java {
        // code style rules
    }
}

2. Add task activation to *Apply tasks

3. Assign convenient keystroke to Build Project

Do this under Settings > Keymap.

Keep in mind that Build Project is using IntelliJ's internal builder. It's incremental (performant), but in case of custom/third-party gradle tasks, the build result might deviate from the $ gradle build result.

In case of a Spring application utilizing DevTools, the build will lead to the changes/updates being served automatically.

With the IDE Hook it should be rather trivial to implement a dedicated Spotless formatter plugin for IntelliJ: https://github.com/diffplug/spotless/blob/master/plugin-gradle/IDE_HOOK.md

So far I wasn't able to find one though.
