Coming back to this a few months later as I did another release of Lab Workflow and Order Entry… it took a little while, but I got this working. There were some mistakes in my .travis.yml and bintray.json, so I updated the above instructions with examples of each. @dkayiwa feel free to take a look and make sure they are good examples…
Also, I missed the step about having to manually set the uploaded file as available, so I copied that up earlier in the instructions.
And finally, I created my own bintray API key and logged into OpenMRS Travis CI and set it there. The instructions weren’t entirely clear on how to do that, but I didn’t want to update because I was confused about the instructions about using the Travis command line client, which I never used?
Thanks for the help!
