Cannot get property jobKey

[xpusostomos]

I've got an app that's been running fine in production for quite a while. Recently I decided to do some development on Windows instead of Linux and I get the following crash when running on Windows, both in intellij and when run as a war. It's exactly the same source code either way, and I've done tons of grails development on Windows before, so I'm a bit stumped... maybe someone will have some clue what's going on

Hi, where is the org.grails.plugins.asyncmail.AsyncMailJob coming from? At first I thought it was from https://github.com/gpc/grails-asynchrounous-mail, but there it's named grails.plugin.asyncmail.AsynchronousMailJob.

What versions are you using of Java, Groovy, Grails and relevant plugins and libraries?

[xpusostomos]

I have my own version of asyncmail, since it was unmaintained for a long time. So yes, it's basically that plugin you mention, with not much differences, I just renamed everything in there "async" since it was inconsistent. I'm using java 17 (I've tried a number of versions), grails 5.3.6, groovy 3.0.18... I'm not sure what other versions you want to know. Oh, it's quartz scheduler 2.3.2 and grails quartz plugin 2.0.13.

[matrei]

I would start by setting a breakpoint on line 59 in AsyncMailGrailsPlugin.groovy to see what the value of the config value sendInterval is.

[xpusostomos]

Hmm, so one problem I had was that I had the build setup to use the plugin installation directly, rather than installing it ( implementation project(":org.grails.plugins.asyncmail") ), and despite that it seemed like... oddly... it might be picking up something old in ~/.m2.... having deleted that and run again, asynchronous.mail.send.repeat.interval is null. Apparently the defaults are supposed to be picked up from asyncmail/grails-app/conf/Plugin.groovy .... I don't know what runs that, or how the values setup there make their way into the config object's getProperty routine, but apparently it doesn't happen on Windows for some reason.
