Build uberjar for Pedestal service

[ja...@knowledgetree.com]

Hi folks,

We're attempting to build a .jar for a pedestal app, but are missing a piece somewhere along the line.

The project.clj is below along with the error produced when attempting to run the jar. Seems like there's a classpath problem or something similar, but I'm not sure.

Any help would be greatly appreciated.

Thanks,
James

I think you have to add this to your :profiles key in project.clj

:uberjar {:aot [myproject.server]}

The :skip-aot true annotation prevents compilation in dev mode.

Thanks, Roman! Your response set me on the right path. I wasn't aware of the :uberjar profile.

I'm actually relying on the aot not to run, so I had to change your suggestion to the following, which works for me.

:uberjar {:main ^{:skip-aot true} [myproject.server]
:dependencies [[io.pedestal/pedestal.jetty "0.2.2"]]}

Thanks again,
James
