我正在按照 google 提供的分步教程进行操作:
https://developers.google.com/+/web/signin/server-side-flow
我已经下载了它提到的用于 Java 的 Google API 客户端库，并且我已经从属性 > 构建路径 > 在 Eclipse 上添加外部 Jars 添加了 Jars。我将所有包含的 jar 文件添加到“libs”文件夹中。
但是当我在后端代码端编写这一行时，
Oauth2 oauth2 = new Oauth2.Builder(
我无法正确解决导入问题，它显示:
Oauth2 cannot be resolved to a type
“libs”中包含的 jar 文件列表是:
google-api-client-1.18.0-rc.jar
google-api-client-android-1.18.0-rc.jar
google-api-client-appengine-1.18.0-rc.jar
google-api-client-gson-1.18.0-rc.jar

有什么想法吗？
谢谢!
最佳答案
您缺少以下 jar :
google-oauth-client-1.18.0-rc.jar
google-oauth-client-appengine-1.18.0-rc
google-oauth-client-java6-1.18.0-rc
google-oauth-client-jetty-1.18.0-rc
google-oauth-client-servlet-1.18.0-rc
可以在这里找到:https://developers.google.com/api-client-library/java/apis/oauth2/v2 在lib文件夹中
