Hello,

Your build issues are most likely linked to

"The only other inconsistency I found in the guide was in the "Configure the LabKey Project in IntelliJ" section when it asks to edit the configurations there is no modules named "api_main" or "org.labkey-api_main", so I continued with "api" instead."

You should see api_main or org.labkey-api_main in the modules list. Please make sure that you have completed the "Clone Core Modules from GitHub" section in the guide properly. Pay close attention to the paths where the cloned repos should go.

Once you've added them you can run a "gradlew projects" command to see if the cloned repos are there under server / modules.

Thanks,
Chet
