Test build failure

Hello I have a java project with gradle build.

I want to build with Java 8. My code used packages removed in java 11, for example javax.xml.bind.JAXBContext

So , in my build.gradle, I have

    java {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }

And I can run gradle tasks build/check/test using the vscode gradle side bar item without issues.

But when I try to launch a test using Test runner, the gradle build fails with "error: package javax.xml.bind does not exist" So it seems to build with Java 11! So why? Does test runner uses another gradle version (where java sourceCompatibility/targetCompatibility is not supported)? Does a workaround exists? I checked also Command -> Configure java runtime , and I have Java 1.8 configured too.

Environment

• Operating System: VScode is running on Windows 10 with a remote-ssh to a Linux workstation
• JDK version: 1.8
• Visual Studio Code version: 1.85.2
• Java extension version: 0.25.15

Could you share a sample project?

@jdneo See attached

I don't know if it is related but in my settings file, I have also

  "java.import.gradle.wrapper.enabled": false,
    "java.import.gradle.version": "7.6.3",

Hi @sebastieng,

Please try to set java.import.gradle.java.home to your jdk 8 installation path and reload your vscode.
