我正在尝试使用Google +中提供的域API，我正在尝试使用域范围委派快速启动java我已按照步骤操作，我也请求我的域管理员授予对我创建的项目的访问权限在控制台中，恢复我可以编译java文件，但是当我运行时，我得到一个404错误，这里是代码：

显然，像我的代码中的电子邮件和密钥文件这样的数据是正确的，这是我得到的错误：

我迷了，如果有人能帮助我，我会很感激。
看来包含PlusDomains.builder的行现在要求调用setApplicationName：
PlusDomains service = new PlusDomains.Builder(httpTransport, jsonFactory, credential)
.setApplicationName('MyDomainsDemo')
.build();
我今天测试了Java样本并且它可以工作。这些说明需要一些与API控制台中标签更改相关的次要更新，但如果正确配置应用程序，您将能够开始使用。
404错误很可能是由错误配置的客户端引起的，并且不是示例中的问题。以下屏幕截图应有助于获取正确的凭据。创建服务帐户时，您将在下面突出显示一个新区域：
确保服务帐户下的客户端ID与从管理控制台执行域范围委派时添加的客户端ID相同。以下屏幕截图显示了客户端ID（上一屏幕截图中的第一个字段）的位置：
最后，请确保src/com/google/plus/samples/quickstart/domains/DomainDelegation.java中配置的电子邮件地址与您服务帐户中的电子邮件相匹配。
如果您使用的是经典API控制台，则需要在项目中添加服务帐户，从API Access - >创建另一个客户端ID ... - >服务帐户执行此操作。这些值将来自添加的部分：
这个有效！

我最近遇到了这个问题。对我来说，解决方案是更新库（示例附带了lib /文件夹中的一堆过时的JAR）。
我的maven依赖：
