Build fails with "java.lang.NoClassDefFoundError" #31
Description
Hi, I'm trying to build FlightPlot from source but I'm getting a "NoClassDefFoundError".
I'm on macOS Big Sur (11.4).
I also needed to update the build.xml file; source and target versions (1.6) are now deprecated. I instead used "1.8".
Here's the complete error log:
`

I'm not familiar with the ant build tool -- how can I fix the problem and build the program?
Thanks!
