当我尝试以下代码时遇到异常：
private ContactsService authenticateId(String userid, String password) {
ContactsService contactService = null;
try {
contactService = new ContactsService("exampleCo-exampleApp-1");
contactService.setUserCredentials(userid, password);
} catch (Exception e) {
System.out.println(e);
}
return contactService;
}
例外：

在我的 .m2 文件夹中，我可以看到它正在获取多个版本的番石榴，因为我可能有其他依赖项，例如 gson，我猜它也在使用番石榴。
尝试在外部为 guava r07 添加依赖，但没有成功。
在我的 POC 示例中，相同的代码就像一个魅力，在该 POM 中，只添加了两个与 gdata 相关的 maven 依赖项。
【问题讨论】：
-
我认为您需要发布一个 pom 文件和 java 类 - 即减少问题 - 其他人可以用来重现错误以便在此处获得帮助。
-
添加了完整的 pom 和 java 代码 sn-p。
