            contactService.setUserCredentials(userid, password);

        } catch (Exception e) {
            System.out.println(e);
        }
        return contactService;

    }

异常:

在我的 .m2 文件夹中，我可以看到它正在获取许多版本的 Guava ，因为我可能有其他依赖项，如 gson，我猜它也在使用 Guava 。

尝试为 guava r07 添加外部依赖，但没有成功。

在我的 POC 示例中，相同的代码非常有用，在该 POM 中，仅添加了两个与 gdata 相关的 Maven 依赖项。

Answer 1

我认为您遇到了 this bug report 中描述的问题

It is very dangerous to use google-collect.jar, as if a user ends up with that and guava on her classpath at the same time, very unpredictable and strange errors can result.

在您的 pom 中声明的其他库(可能是 GSON)隐式地将 Guava 添加到您的类路径中。而你只是遇到了这些“不可预测和奇怪的错误”;-)

StackOverflow 上有人有 similar problem .也许你可以像他那样做，即明确声明 rc05 版本的 Guava 以强制 maven 使用这个版本？ (参见:this answer)
