我在运行良好（单元测试）的 java 文件（GcpEncrypt.java）中有以下块。

但是，当我将其 jar 并从 a 中调用它时logstash Jruby input plugin，它会挂在客户端创建部分。

public byte[] decryptWrappedKey(String wrappedKey, String cid)
      throws IOException {

    if (this.testMode) { logger.log(Level.INFO, "Decrypting wrapped key");}

    byte[] wrappedKeyBytes = Base64.decodeBase64(wrappedKey);

    // Create the KeyManagementServiceClient using try-with-resources to manage client cleanup.
    if (this.testMode) { logger.log(Level.INFO, "Creating KMS Client ...");}
    try {
      KeyManagementServiceClient client = KeyManagementServiceClient.create();
      logger.log(Level.INFO, "ENTERED KEY CREATION");
      String keyResourceName = CryptoKeyName.format(
        this.projectId,
        this.locationId,
        this.keyRingId,
        cid);

      // Decrypt the ciphertext with Cloud KMS.
      if (this.testMode) { logger.log(Level.INFO, "Decrypting KMS response"); }
      DecryptResponse response = client.decrypt(keyResourceName, ByteString.copyFrom(wrappedKeyBytes));
      if (this.testMode) { logger.log(Level.INFO, "Returning decrypted wraped key"); }
      client.close();
      logger.log(Level.INFO, "**************CLOSING KMS CLIENT ***********");
      return response.getPlaintext().toByteArray();
    }catch (Exception e) {
      throw new RuntimeException(e);
    }
  }

我可以看到ENTERED KEY CREATION日志，然后它就挂了，我该如何调试呢？

KeyManagementServiceClient通过将 实例化为实例变量，我能够找到相关的。似乎'com.google.cloud', 'google-cloud-kms', '0.81.0-beta'罐子缺少com/google/cloud/kms/v1/ListKeyRingsRequest课程。
