java - Google OAuth Credential.refreshToken 上的连接重置

Question

我正在尝试使用服务帐户创建凭据(以便检索 Google Analytics(分析)信息)。
但是当 Credential.refreshToken(..) 被调用时，我得到一个
java.net.SocketException:连接重置。

我已使用 Google Developers Console 创建了一个 OAuth 服务帐户和一个 P12 文件。然后我执行以下代码:

// Create the credential

HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
JsonFactory jsonFactory = JacksonFactory.getDefaultInstance();
File p12File = new File(System.getProperty("user.home"), ".store/analytics/my-project.p12");
Set<String> serviceAccountScopes = Collections.singleton(AnalyticsScopes.ANALYTICS);

GoogleCredential.Builder builder = new GoogleCredential.Builder()
    .setTransport(httpTransport)
    .setJsonFactory(jsonFactory)
    .setServiceAccountId("123abc<etc>@developer.gserviceaccount.com")
    .setServiceAccountPrivateKeyFromP12File(p12File)
    .setServiceAccountScopes(serviceAccountScopes);

GoogleCredential credential = builder.build();

// Attempt to refresh the credential's token
credential.refreshToken();

这会导致短暂的暂停，然后出现以下异常:
