mantle-usl | Mantle Universal Service Library | Business library

Please see the Moqui component structure documentation here for a description of directories and files used by convention in components:

https://www.moqui.org/docs/framework/Tool+and+Config+Overview#extensions-and-add-ons

There was a description of the 'lib' directory there, which is how you get JAR files on the classpath in a Moqui component. I just added some additional details for supported files as well including build.gradle with notes related to this question.

In short the real question is how to get stuff on the Java classpath and that is done using the 'classes' and 'lib' directories in a Moqui component directory. What you're missing is something in your build.gradle file to copy built and depended on JAR file to the 'lib' directory. Here is an example of something you can add to your build.gradle file to do this:

The mantle-usl component doesn't have any compiled code in it so the build.gradle file does not build a jar file, it is only used for running the Spock tests.

I wouldn't recommend adding your own code to mantle-usl, it is easier and cleaner to put it in a separate component. For an example of a build.gradle file that does build a jar file look at the moqui/example component or most of the moqui tool components (such as moqui-elasticsearch).

You also don't need to modify the main build.gradle file from the moqui-framework repository, dependencies should be declared in the build.gradle file in each component (which are picked up automatically in the main build).
