-
-This plugin uses the [Gradle JApiCmp](https://github.com/melix/japicmp-gradle-plugin) plugin
-to generate API Diff reports for each Spring Framework module. This plugin is applied once on the root
-project and creates tasks in each framework module. Unlike previous versions of this part of the build,
-there is no need for checking out a specific tag. The plugin will fetch the JARs we want to compare the
-current working version with. You can generate the reports for all modules or a single module:
-
-```
-./gradlew apiDiff -PbaselineVersion=5.1.0.RELEASE
-./gradlew :spring-core:apiDiff -PbaselineVersion=5.1.0.RELEASE
-```
