Yes but you're smart

Well I got it working with only a bit of tweaking from what I had been using before. I'm not exactly sure what change fixed it, but here's what I did:
- In my manifest file, I changed the name, author, and version from the template file defaults
- I downgraded my Java from OpenJDK 8 to Java SE 5
- I changed my build.sh file to remove the -target 1.4 stuff
build.sh

Spoiler:

#!/usr/bin/zsh
rm Test.jar
rm app.azw2

javac kindlet/*.java
jar cvmf test.manifest Test.jar kindlet
jarsigner -keystore developer.keystore -storepass password Test.jar dktest
jarsigner -keystore developer.keystore -storepass password Test.jar ditest
jarsigner -keystore developer.keystore -storepass password Test.jar dntest

mv Test.jar app.azw2

Thank you so much for your help! And I was able to put off figuring out Ant!
