Compile WAR file Assistance - code clean-up. -- 2

I'm encountering Groovyc errors while trying to compile my WAR file for a project that uses Java(1.7.0), Kotlin, Groovy, and Grails. The example error I keep encountering is "Groovyc: unable to resolve class ec.core.Notification".

I've been using Gradle as my build tool, managing dependencies from a local repository. The project is based on Grails 2.x.

The ideal freelancer for this project should:
- Have extensive experience with Gradle and Grails 2.x.
- Be skilled in Java, Kotlin, Groovy, and Grails.
- Have a proven track record of resolving Groovyc errors.
- Be able to help me compile the WAR file without errors.

In addition:
Other Errors:
1) Need Google API for map/location
"Google Cant Load Map Correctly"

2) Cannot login via APK. This is related to Google API.
"Failed to authenticate given credentials"

3) Admin account cannot login. Does not import MYSQL admin account into DB.
Admin account goes to another screen. It imports when I restore admin database on my local pc database. I can show in my pc. just need admin account to be restored in my database on the windows 2022 server.

Also I will need you to build the WAR file on my PC via Anydesk, So I can do it in the future.

Please reach out if you're able to help. Thank you.
