如Bjorn所提到的，您需要启用-enableassertions。
可以通过使用自定义运行时而不是默认的AWS来实现。这里有一个使用自定义运行时的示例 - https://github.com/andthearchitect/aws-lambda-java-runtime
注意：还有一个选项JAVA_TOOL_OPTIONS，在尝试检查自定义运行时之前，请尝试使用它。
另一个选项可以是将断言替换为类似以下的内容：
if (!condition) {
throw new AssertionError();
}
如果是您自己的代码，第二个选项听起来更好。
英文:
As mentioned by Bjorn you have too enable -enableassertions.
It is possible to have them but with using custom runtime not the default AWS.
Here is one example of having custom runtime - https://github.com/andthearchitect/aws-lambda-java-runtime
Note: There is an option JAVA_TOOL_OPTIONS, please give it a try before checking custom runtime.
Another option could be just replace asserting with something like .
if (!condition) {
throw new AssertionError();
}
If it is your own code second options sounds better.

启用断言需要使用-enableassertions启动命令。不幸的是，在AWS Lambda中无法向JVM传递参数，只支持环境变量。回答你的问题：不，这是不可能的。
英文:
To enable assertions assertions you need to use the -enableassertions startup command. Unfortunately you cannot give arguments to the JVM with AWS Lambda. Only environment variables are supported. To answer your question: no this is not possible.
