Google Refresh_token过期后不会生成访问令牌。 Refresh_token无法创建新的Access_token

Question

我正在尝试使用Java客户端库访问Google表格。首次访问令牌和刷新令牌已生成并存储在File。（StoredCredential）中。访问令牌过期后，将不会使用“刷新令牌”生成新令牌。请建议可以做什么。

示例代码：

 GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
                HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
                .setDataStoreFactory(new FileDataStoreFactory(new java.io.File(TOKENS_DIRECTORY_PATH)))
                .setAccessType("offline")
                 .build();
        LocalServerReceiver receiver = new LocalServerReceiver.Builder().setPort(8888).build();
        return new AuthorizationCodeInstalledApp(flow, receiver).authorize("user");
