How did you import the project into VSC?

[reef zodiac]

I just import spring framework source code into vscode . I don't know how to configure vscode setting.json.

[glossy horizon]

I realized that but how exactly did you do it?

Does it show a Java build window?

[reef zodiac]

vscode gradle extension works well

[glossy horizon]

Is there something like that on the bottom?

[reef zodiac]

yes

[reef zodiac]

but java extension is on the left of gradle.

[glossy horizon]

Can you show it?

[reef zodiac]

Yeah! But I need to show it tomorrow because it is on my school's computer.

[glossy horizon]

well I can't tell you without you showing me these things

but it's fine at any point in time

[reef zodiac]

Thanks for your help.

Hi, Daniel! My vscode show this errors:

The Java extension reports:

The gradle extension works well:

And my user setting.json is following:

Is there a bar at the very bottom of VSC?

[glossy horizon]

Can you expand the dependencies of one of the projects with errors?

[reef zodiac]

These actions happen when I start the vscode :

[glossy horizon]

click on the "Grafle: configure project" thing

What's shown in whatever pops up?

What Java version are you using?

[reef zodiac]

I find that the error happens after the initialization of java extension is completed.

[glossy horizon]

Can you build it from the CLI?

[reef zodiac]

I use jdk 23 and the gradle extension works well.

[glossy horizon]

I guess there is more stuff being shown there afterwards?

[reef zodiac]

The error disappears now.

[glossy horizon]

Is there anything more shown in the gradle build output if you wait?

[glossy horizon]

Seems like VSC uses JDK 17 for the Gradle build - idk whether Spring allows that

or maybe even a JRE

[reef zodiac]

It is working for a long time.

[glossy horizon]

you might want to try setting set Gradle JVM to your Java 23 JDK explicitly

or JDK 21 should work as well

[glossy horizon]

check the settings in VSC

[reef zodiac]

this is the output of gradle extension:

[glossy horizon]

Did you set it to JDK 21 or 23?

Does it work now after the build completed?

[reef zodiac]

Thanks very much!! When I set it to jdk 21, the errors disappear!!
