1. Go to the publish dir and find logs.zip (different then logs/ directory) and download it to your laptop.
2. Extract the logs.zip
3. The logs are in EBCDIC so you can't immediately cat/edit/grep through them. You can grab e2a binaries/source from https://github.ibm.com/WASL3/ecurep-btrace/tree/master/tools/e2a to use on your VM or laptop.
4. Start by checking makezos.5.log and look for compile or link errors (WARNINGS probably n/a)
5. For example: $ e2a makezos.5.log|grep plugins.http
