Is there an error message when you opened your project in VSCode? - Click the bell icon at the bottom right corner

[olgapshen]

No... No such message while oppening the IDE or during the usage.

@olgapshen I believe your issue duplicates with #2655 (comment) and microsoft/vscode-java-debug#1212. The JDK on OpenSUSE doesn't contain the release file, that breaks the Java extension.

[olgapshen]

Hi! Several new things.

First of all, I upgraded Gradle to 7.5.1 and successfully built the project with VSCode Gradle plugin.
The screenshot below.

Second I messed little button in bottom of the screen: "Lightweight mode", I pressed, and IDE tried to build the Java project, but with new errors.

I updated the logs in the repo:

• Client log
• Server log

Sorry, but no, as I see I have release version since it doesn't have -devel suffix.
And I just updated the package:

Looking at the logs you shared, it's exactly same as #2655 (comment) and microsoft/vscode-java-debug#1212.

A quick workaround is to manually create a release file in your jdk home.

sudo sh -c 'echo "JAVA_VERSION=\"11.0.16.0\"" > /usr/lib64/jvm/java-11-openjdk-11/release'
