Spring Boot 3 with Gradle and Java 17 not working in VS Code Could not resolve org.springframework.boot:spring-boot-gradle-plugin:3.1.2

Question

I have a Spring Boot 3 project with Gradle and Java 17. I want to work with it using VS Code. I have the Java extension pack, the Spring Boot extension pack and the gradle extension in VS Code.

I can use the same project without problems in Eclipse. I also tried using a new project from start.spring.io. The projects work with the following configurations:

Maven + Java 11 + Spring Boot 2.7.14
Maven + Java 17 + Spring Boot 3.1.2
Gradle + Java 11 + Spring Boot 2.7.14

The log shows the following error, when i try to open the project:

After reading some other questions (like this one or that one), I thought gradle uses java 11 but gradle --version gives the following output:

$ gradle --version

I also set the VS Code setting Java › Import › Gradle › Java: Home to the JDK-17. What I find strange is that gradle build is working fine and also in the gradle view in VS Code the Spring Boot dependencies are listed.

This did the trick. I set the runtime configurations in VS Code and now it works. Thank you! Do you want to answer the question so that i can set it as the accepted answer? — Ole, Aug 10 '23 at 19:04

You can configure JDK for your project via java.configuration.runtimes configuration.

Example:

"java.configuration.runtimes": [
  {
    "name": "JavaSE-1.8",
    "path": "/usr/local/jdk1.8.0_201"
  },
  {
    "name": "JavaSE-11",
    "path": "/usr/local/jdk-11.0.3",
    "sources" : "/usr/local/jdk-11.0.3/lib/src.zip",
    "javadoc" : "https://docs.oracle.com/en/java/javase/11/docs/api",
    "default":  true
   },
   {
    "name": "JavaSE-12",
    "path": "/usr/local/jdk-12.0.2"
   },
   {
    "name": "JavaSE-13",
    "path": "/usr/local/jdk-13"
   }
]

This works when I do it like this for the JDK 17 :) thx – Ole Aug 11 '23 at 08:18 — Ole, Aug 11 '23 at 08:18
