我们需要互联网连接到AWS实例内使用AWS的Java SDK？
我有一个实例的VPC中运行，而我还没有分配任何公共IP地址。
从什么我的初步调查发现，我看到从这个例子在亚马逊上运行的基于AWS Java SDK的Java程序，实例需要有互联网连接。
运行示例程序AwsConsoleApp随AWS Java SDK中，我看到了以下错误：
[javac的] /home/ubuntu/aws-java-sdk-1.8.9.1/samples/AwsConsoleApp/build.xml:12：警告： 'includeantruntime' 没有设置，默认为build.sysclasspath =最后; 设置为false重复构建【JAVA] ========================================= ==【JAVA]欢迎AWS Java SDK的！ 【JAVA] ===========================================

我发现这违背了亚马逊如何提供访问其EC2Metadata服务。
有没有什么办法可以不提供的AWS实例公共IP运行这些Java程序？
