java has been set to 11 as default

Environment

• Operating System: Ubuntu 20.04
• JDK version: 8/11/17
• Visual Studio Code version: 1.78.2
• Java extension version: 0.25.11 (Extension pack for java)

Steps To Reproduce

1. install java 17 (upgrade alternative to it)
2. go to https://start.spring.io/ -> Gradle Groovy, Java, 3.1.0, jar, 17 and generate
3. open it in vscode

Current Result

org.springframework.boot.gradle 3.1.0 can't be resolved,
(Incompatible because this component declares an API of a component compatible with Java 17 and the consumer needed a runtime of a component compatible with Java 11
- Other compatible attribute:
- Doesn't say anything about its target Java environment (preferred optimized for standard JVMs))
the language support plugin is uses java 11 as default to import, even if the seourceCompatibility has been set and
the gradle.properties org.gradle.java.home=/usr/lib/jvm/java-17-openjdk-amd64 on project level has been set (root folder)

The only way was to resolve is "java.import.gradle.java.home": "/usr/lib/jvm/java-1.17.0-openjdk-amd64", which is painful to figure out, intellij is behaving similarly (Gradle JVM needs to be set -> hasn't tested the gradle.properties in this case)

Expected Result

I would have expected:
a) whatever the JAVA_HOME sais, and the java.import.gradle.java.home is not set,
it's using the JAVA_HOME for gradle import also. (command line is using it)
b) if gradle.properties has been set is picking up java folder from there

It is the behavior being described in the official gradle manual.

Additional Informations

I'm using gradle for java plugin also.
The difference between intellij and vscode was, that the Gradle JVM had a default value. (randomly selected one)

After several attempt and screw up, cleaning up language server (ctrl+shift+p -> relevant command) didn't help, just removing all the workspace folder,
remove the project from workspace and restart and add back the project.

In this case java classes has been identified as non-project files!

首先使用 Java 17 从 start.spring.io 复现 Gradle Groovy 项目，然后检查导入期间如何选择 java.import.gradle.java.home、JAVA_HOME 和项目的 gradle.properties。完成的标准是扩展无需显式设置即可使用预期的 Java 17 runtime，并将 Java 类识别为项目文件。
