Start in servlet/spring-boot/java/oauth2/login/build.gradle, especially the plugins block reported at lines 2-3, and reproduce with ./gradlew bootRun from that directory. Compare the plugin declarations with the Gradle 8.3 error and verify that the sample builds and starts successfully with bootRun.
