"Symbol is declared in unnamed module which is not read by current module" kotlin(JAVA_MODULE_DOES_NOT_READ_UNNAMED_MODULE)

[edechamps-Google]

Steps to reproduce in VS Code with the Gradle and Kotlin extensions:

1. Check out square/okhttp@690d1df
2. Open okhttp/src/commonJvmAndroid/kotlin/okhttp3/OkHttpClient.kt
3. Wait for things to build and settle (approx. 3 minutes)

The problem:

OkHttpClient.kt has lots of spurious "Symbol is declared in unnamed module which is not read by current module kotlin(JAVA_MODULE_DOES_NOT_READ_UNNAMED_MODULE)" diagnostics shown all over the place. This is despite Gradle building the entire project without any issues.

It looks like this error is showing up on every usage of a class from a dependency outside the project, including standard JDK Java classes and even Kotlin standard library classes.

Additional information:

• Using JDK 17 in both Gradle and Kotlin extensions
• VS Code 1.105.0
• Gradle for Java extension version 3.17.2025090802
• fwcd Kotlin extension version 0.2.36
• fwcd LSP version 1.3.13 (auto-downloaded by the extension)
