Gradle projects do not build correctly (the bin/ directory again)

#634 is the underlying issue, but that was closed by brushing it under the carpet (IMO it deserves to be fixed). The problem I have is actually worse - the classpath is incomplete because it doesn't contain resources created and/or copied into build/resources/main (for instance) by script targets in the build. It's easy to reproduce the problem - here's an example: https://github.com/scratches/vscode-gradle-nonsense (load it up in VSCode and try and run the tests from the codelens and they fail, even though the build succeeds from command line).

リンクされた再現リポジトリから始め、VSCode codelens からテストを実行した場合と、コマンドラインで成功するビルドを比較します。issue #634 と関連する vscode-java-debug issue を読み、その後、build/resources/main に作成またはコピーされたリソースが codelens のテストクラスパスでどのように表現されるかを追跡します。これらのリソースを利用可能な状態で、再現されたテストが正常に実行できれば完了です。
