If the output of an external command execution results in a fatal error, jpackage will print the command line of the external command. In quiet mode (without "--vrebose"), it will also print the command's output.

E.g. (unit test output):

jpackage --input MainTest\testFailedCommandOutput\input --dest MainTest\testFailedCommandOutput\output --name FailedCommandOutputMainTest --type app-image --main-jar hello.jar --main-class Hello --win-console
Error: Unexpected exit code 17 from executing the command jlink-mock --output MainTest\testFailedCommandOutput\output\FailedCommandOutputMainTest\runtime --module-path runtime\jmods --add-modules java.base,jdk.xml.dom,jdk.zipfs --strip-native-commands --strip-debug --no-man-pages --no-header-files
Command output:
It
fell
apart
