FlexUnit - Mismatch version of the CIListener library causing "command not understood"

By xngo on February 26, 2019

If you are running FlexUnit through Ant and getting the following error:

java.util.concurrent.ExecutionException: 
  command [<testcase classname='MyTestCase' name='MyMethod' time='0.000'  status='success'/>] not understood

This is due to the mismatch in version of the CIListener library. For my case, I was using Flex 4.1 to compile my codes and using FlexUnit 4.0 to run my compiled code. To remedy this, I went to flexunit.org to get the latest version of FlexUnit(flexunit-flex-4.1.0-RC1-77-sdk4.0.0.14159.zip).
