Explicit non-Quarkus dependencies not resolved in classpath

[pradeepvenkataraman]

Relevance Confirmation

• I confirmed that this is not an issue with the Eclipse JDT Language Server itself

What happened?

In a Quarkus Gradle project, transitive dependencies pulled in via Quarkus extensions are correctly resolved, but explicit direct dependencies that are not part of any Quarkus extension (e.g. jackson-dataformat-csv) are missing from the JDT LS classpath, causing false import errors. Gradle compiles fine.

• Extension version: 6.8.17
• Quarkus version: 3.35.2

What did you expect to happen?

Zed Java LSP does not show errors for such external dependencies

Environment

Zed: v1.2.2
Platform: macOS 26.5
Java: Oracle GraalVM 25.0.3+9.1

Thanks for reporting, could you test the same project in VS Code? Let me know whether the same issue happens over there, if not there could be some configs that we are omitting.

As a workaround, you could try running gradle eclipse (with the eclipse plugin applied in your build.gradle) to generate .classpath files that JDTLS can pick up directly, bypassing Buildship's sync.

Also, are you using the configs reported in the README?
