Error when compile usng openjdk11

[yhojann-cl]

I use this setting: https://start.spring.io/#!type=gradle-project&language=java&platformVersion=3.0.0-SNAPSHOT&packaging=jar&jvmVersion=11&groupId=com.example&artifactId=demo&name=demo&description=Demo&packageName=com.example.demo&dependencies=data-jpa,postgresql,web,security,oauth2-client,validation

And ubuntu 22.04 LTS (or docker container) and OpenJDK 11 JRE package, but when try compile says:

$ java -version
openjdk version "11.0.15" 2022-04-19

BUILD FAILED in 475ms

I use the native OpenJDK 11 and starter project without modifcations. Is a gradlew, java or initializer problem?

Spring Boot 3.0 requires Java 17.

[yhojann-cl]

But in https://start.spring.io/ i can chose Java 8 and Spring 3, you need disable selection when chose spring 3.

[wilkinsona]

We'd like to be able to do that. Unfortunately, it's not possible at the moment. Please see #832 and #910 for details. The best that we can do at the moment is to silently upgrade the generated build scripts to Java 17. This happens in your example link where you'll see sourceCompatibility = 17 in the resulting build.gradle.
