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

install java 17 (upgrade alternative to it)
go to https://start.spring.io/ -> Gradle Groovy, Java, 3.1.0, jar, 17 and generate
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!

@fssrepository

@fssrepository I can't reproduce the issue.
Could you run the following commands:

$ echo $JAVA_HOME 
$ java -version

openjdk version "17.0.7" 2023-04-18
OpenJDK Runtime Environment (build 17.0.7+7-Ubuntu-0ubuntu120.04)
OpenJDK 64-Bit Server VM (build 17.0.7+7-Ubuntu-0ubuntu120.04, mixed mode, sharing)

You should set JAVA_HOME.
You have to check if it is /usr/lib/jvm/java-1.17.0-openjdk-amd64 or /usr/lib/jvm/java-17-openjdk-amd64

$ which java

JAVA_HOME has been automatically set, while java 17 installer was running.

JAVA_HOME => /usr/lib/jvm/java-17-openjdk-amd64

The problem, as i said is plugin one.
"./gradlew build" from terminal was perfectly fine, without any configuration.
It was reacting also to gradle.properties. (i set to java 11, and it failed right away with the error above)

The plugin either the gradle for java, or the language support is hard coding java 11, because it was the first version from which these plugins have got support. I had to upgrade to java 11 from java 8, as it was not working. (a year ago)

It's causing issues only on gradle import, but building the source code to java 17. The plugin itself is printing out java 17, and screwing up at gradle import.

plugins {
id 'java'
id 'org.springframework.boot' version '3.1.0'
id 'io.spring.dependency-management' version '1.1.0'
}

group = 'com.raxim'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'

when id java is running picking up the 17 source compatibility (using java 17), but the
id 'org.springframework.boot' version '3.1.0' is trying to make a gradle import on java 11.

What went wrong:
A problem occurred configuring root project 'myscoutee'.

pls. don't confuse that i have upgraded the 8.1.1 lately, same problem...It happens inside the vscode, but not from command prompt (I have also multi jdk, 17 is default, but i have 8 and 11 installed also)

/usr/lib/jvm/java-1.17.0-openjdk-amd64 or /usr/lib/jvm/java-17-openjdk-amd64 does not make that much difference, the 1.17 is a simplink to the 17, which is a simplink to an openjdk-17..."really nice stuff". however installer set up the JAVA_HOME not me.

Could you try

$ export JAVA_HOME=/usr/lib/jvm/java-17-openjdk-amd64
$ export PATH=${JAVA_HOME}/bin:$PATH
$ cd <your_project_root>
$ code .

I am also facing the same problem.

Same problem here, the plugin doesn't go well with jdk 17

Then the next version of the plugin needs to do something with your solution, as that jdt.ls and other things can't be that manual to cause months of trouble. My feeling also there is some stability issue, which hasn't happened before. Java files are not parsed, sometimes code is not clickable. The code also, if something wrong in the block. For example in methods or java lambda, then i need to revert back and start over. (brackets etc.) Too many times i need to restart vscode or cleanup the cache. If there is a never ending process in debug, that one also would be helpfull, if it could have been identified in the task bar, or from the vscode ui, to kill. Peter

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)

The exact Precedence is below.

settings.json java.import.gradle.java.home
settings.json java.jdt.ls.java.home (Default is Red Hat embedded JRE)
settings.json java.home (deprecated)
env var JAVA_HOME
env var PATH

The design problem is that the Gradle extension references java.jdt.ls.java.home for the Red Hat extension language server. This is counter-intuitive.
