May 5, 2026 - The above example tells spotless where our Java classes are and to exclude the build directory. The rest of the options are fairly self-explanatory. toggleOffOn() adds the ability to have spotless ignore specific portions of a project. The usage looks like the following · // format:off public void myWeirdFunction() { } // format:on · googleJavaFormat() tells spotless to format according to the Google Style Guide

String groupArtifact = this.groupArtifact != null ? this.groupArtifact : GoogleJavaFormatStep.defaultGroupArtifact();

August 10, 2022 - In order to setup a standard in regards to code formatting, we need to setup either a common configuration file to be imported by everyone or we can use something like Spotless which could be configured to use existing code formatting standards including Google Java Format and others.

Here is an example: plugins { id 'com.diffplug.gradle.spotless' version '6.18.0' } spotless { java { googleJavaFormat() } } In this example, we are using the Google Java Format to format our Java code.

June 17, 2024 - spotless.java { googleJavaFormat() targetExclude("build/**") } This will enable the following Gradle tasks among others: spotlessApply to fix up the code in-place. spotlessCheck to run the formatting checks without changing the files.

July 17, 2019 - Ideal way of doing this would be to use both googleJavaFormat("1.7") and indentWithSpaces(4) in the order and expect spotless to apply them in the given order and get the required result.

July 24, 2024 - We’ll remove the <googleJavaFormat/> step and replace it with a <eclipse> formatter that uses the settings from our custom XML file: <plugin> <groupId>com.diffplug.spotless</groupId> <artifactId>spotless-maven-plugin</artifactId> <version>2.43.0</version> <configuration> <java> <eclipse> <file>${project.basedir}/baeldung-style.xml</file> </eclipse> </java> </configuration> </plugin>

As you can see in the example below, this configuration formats both Java and YAML files. For the full list of available options, please refer to the official documentation. plugins { id("com.diffplug.gradle.spotless") version "7.0.0.BETA1" } spotless { java { // Format using Google Java Format. // The argument specifies the Google Java Format version. googleJavaFormat('1.22.0').aosp().reflowLongStrings() formatAnnotations() } yaml { target '**/*.yaml' jackson() } }

// Example of a Spotless Maven config in pom.xml <plugin> <groupId>com.diffplug.spotless</groupId> <artifactId>spotless-maven-plugin</artifactId> <version>2.8.0</version> <configuration> <java> <googleJavaFormat('1.9')> <skip>false</skip> </googleJavaFormat> </java> </configuration> </plugin>
