known issues

(Eclipse): If importing of a Gradle project with an old Gradle Wrapper version into Eclipse fails it is likely because STS is running on Java 25 be default. Please specify "Java home" folder in the Gradle Project Import Wizard that points to the JDK/JRE version compatible with the Gradle Wrapper version.
(Spring Boot): Support for Spring Boot major and minor version upgrades via OpenRewrite recipes got removed. We recommend
use the Maven or Gradle plugins on the command line instead.
