IntelliJ AWS SAM UnicodeDecodeError

Question

我对AWS和lambda函数完全陌生。目前，我尝试使用IntelliJ和Java启动我的第一个"Hello“程序。我用AWS在Java中编写了Lambda函数。我想在本地使用Maven容器中的启动它(因为我没有Docker)。

在解决了其他一些错误之后，我在点击start之后得到了这个错误

SAM Build finished exceptionally: Command did not exist successfully, exit code: 1

早些时候，我收到了一个警告，UTF8有问题，所以代码在某种程度上依赖于平台，但老实说，我有0条线索。

Java版本 15.0.2

SAM版本 1.18.1

Apache版本 3.6.3

下面是对整个过程的追溯：

您可以使用和IntelliJ编写Lambda函数。您可以使用Lambda控制台构建JAR文件并部署Lambda函数。一旦部署了Lambda函数，就可以从Lambda控制台测试它。

您可以将消息记录到云监视日志。使用IntelliJ IDE中的Lambda运行时API，您将避免这些异常。您将编码您的逻辑并部署JAR文件，它可以工作。

此外，您可以很容易地使用额外的AWS从Lambda函数调用AWS服务。

要查看使用Lambda运行时API一步一步创建Lambda函数的AWS文章，请参见：
