Question

我正在尝试验证驱动器中的访问令牌：

GoogleCredential credential = new GoogleCredential.Builder()
    .setClientSecrets(clientId , clientSecret)
    .setTransport(TRANSPORT)
    .setJsonFactory(JSON_FACTORY)
    .build();

credential.setAccessToken(accessToken);

Drive service = new Drive.Builder(TRANSPORT, JSON_FACTORY, credential).build();

但我在最后一行收到错误

Caused by: java.lang.NoSuchMethodError: com.google.api.client.json.JsonObjectParser.  <init>(Lcom/google/api/client/json/JsonObjectParser$Builder;)V
[INFO]  at  com.google.api.client.json.JsonObjectParser$Builder.build(JsonObjectParser.java:163) ~  [google-http-client-1.17.0-rc.jar:1.11.0-beta]

我尝试更改不同版本的库，但同样的错误仍然存在。那么，错误是什么？我们错过了一些图书馆吗？

Answer 1

你在使用这个库吗？

谷歌-HTTP-客户jackson2-1.17.0-rc.jar

你可以找到它here。

Answer 2

我得到了同样的错误。通过在pom.xml中更新驱动器api库的版本来修复它。那你应该打电话给

mvn clean package

您可以在Maven存储库中找到最新版本的Google库：

http://mvnrepository.com/artifact/com.google.apis/google-api-services-drive
