Spotless Gradle googleJavaFormat default version google-java-format

💡 Result:

The default version of google-java-format used by the Spotless Gradle plugin is determined dynamically based on your JVM version [1][2]. As of July 2026, for users running on JVM 17, the default version is 1.28.0 [1][2]. Spotless manages this via an internal dependency management system [1]. While the plugin provides a recommended default, you can explicitly override the version in your build configuration [3][2]: spotless { java { // Overriding the default version googleJavaFormat('1.28.0') } } The plugin also supports additional configurations such as using the AOSP style, reflowing long strings, and toggling Javadoc formatting [3][2]: spotless { java { googleJavaFormat('1.28.0').aosp.reflowLongStrings.formatJavadoc(false) } } If you are using different JVM versions, the minimum required version may vary; for instance, Java 21 requires at least version 1.17.0 [1][2]. The plugin's maintainers regularly update these default versions to match the latest available releases of google-java-format [4].

Spotless 8.9.0 google-java-provider googleJavaFormat version 1.34.0 README

💡 Result:

In Spotless 8.9.0, the google-java-format version is not hardcoded to 1.34.0 as a default. Instead, Spotless allows users to specify the version they wish to use in their build configuration [1][2]. For google-java-format, the default version provided by Spotless is managed internally and may update across releases [3]. As of the release of Spotless 8.9.0 (dated July 27, 2026), you can explicitly override the version to 1.34.0 or any other compatible version in your build.gradle or pom.xml [1][2]. To use a specific version (such as 1.34.0) in Gradle, you would use the following configuration in your spotless block [1][2]: spotless { java { googleJavaFormat('1.34.0') } } The google-java-format version 1.34.0 was released on February 3, 2026 [4], and it includes support for Java 25 Instance Main Methods [5]. Users are encouraged to check the official Spotless CHANGES.md and the google-java-format release notes for details on compatibility and new features [6][7].

Configure Spotless to use 1.34.0 explicitly.

google-java-format = "1.34.0" only updates the project dependency alias; Spotless still uses its internal default formatter version unless the version is passed via googleJavaFormat(...).

Proposed fix

-    googleJavaFormat()
+    googleJavaFormat("1.34.0")
