Groovy: No suitable ClassLoader found for grab

Question

I know there are like 10 other posts about this topic, but none of the answers work for me right now, not even my own previous post when I ran into this before because that time it was working on my CentOS linux server just fine but was failing when I was running it from IntelliJ on my Mac.

Now I have the opposite problem. It's working on my Mac but not on my linux server. I've just migrated to a new CentOS 7 server and now it's not working when I run it from the command line on my CentOS 7 server.

Here is the stop of my script:

#!/usr/bin/env groovy

@Grab('mysql:mysql-connector-java:5.1.25')
@GrabConfig(systemClassLoader = true)

import groovy.sql.Sql
import groovy.util.GroovyScriptEngine

String reportdate
if (args.length > 0) {
        reportdate = args[0]

} else {
        def today = new Date()
        def yesterday = today - 1
        reportdate = yesterday.format("yyyy-MM-dd")
}

Here is the error output:

$ ./smart_daily_fetch.groovy 
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:

How did you install groovy? I suggest using sdkman. http://sdkman.io/ — Luis Muñiz, Jan 31 '17 at 13:49
I used yum to install it. I took your advice, had yum remove groovy, installed sdkman, installed groovy with sdkman, and then groovy worked perfectly. Thank you! If you post this as an answer, I'll accept it. — Kenny Wyland, Jan 31 '17 at 19:03

The version that comes with the linux distributions and available on the repositories is usually way out of date. I recommend sdkman to manage the versions of groovy/gradle/grails and many other sdks.

Get it here:
