Jira plugin development Error - Compilation Failure

On step 2 of the Hello World plugin tutorial I run into the following Compilation failure error:

I show Javac - version and the SDK installed successfully

and JAVA_HOME is set appropriately to C:\Program Files\Java\jdk1.8.0_221 and added to the path as a variable as %JAVA_HOME%\bin

I am aware of the solution described here: https://community.atlassian.com/t5/Jira-questions/Getting-quot-Compilation-Error-No-compiler-is-provided-quot-but/qaq-p/529288

but that does not seem to be my issue; I have only one instance of JDK installed and one JAVA_HOME variable. Help!?
