原因

Java 8 was found to be installed on the host, which is below the required version.

解决方案

Ensure that the supported version of Java is installed on the Linux Host.

其他信息

See the AppSync User Guide to review all pre-requisite items for the AppSync CLI when run on Linux.

For AppSync 4.2.0.0, Java 11 is required per page 21 of the AppSync 4.2 User Guide which states:     
 
Java Runtime Environment (JRE) version 11 - must be installed and available in path.
 
It is also prudent to ensure the customer defined AppSync CLI folder on the Linux host contains the CLI from the current running AppSync Server version. It is possible the AppSync Server was upgraded one or more times since the AppSync CLI was originally copied over to the Linux host.
