Additional Informations

After checking log, it was found that the Language Server failed to include classes from workspace dependencies into the class path.

If the classifier of dependency is not specified, class path is constructed correctly.

vscode.java.test.runtime.classpath に対する workspace/executeCommand リクエストから始め、ServiceTestA の test001 を含む、リンクされたマルチプロジェクトサンプルを使って問題を再現します。dependency classifier を指定した場合に返される classpath を比較し、テストが成功するように project-b/target/classes が含まれていることを確認します。
