Grails - Database Reverse Engineer plugin not found - grails

Question

Environment
Grails 2.4.4
PostgreSQL 9.4
JDK 1.7
I've been trying to get this plugin to work. (I'm still a grails newbie, not to mention programming.)
I tried to do everything I can find out there but still get this untimate error message.

Please make a selection or enter Q to quit:
This is what I have right not in my config files. (I've tried to change a lot of them, such as Hibernate, plugin version etc, but always end up with that message.)

}
Thanks in advance.
EDIT 1
So, I changed DbReverseEngineer.groovy under Script folder like this.
mergedConfig.driverClassName = dsConfig.driverClassName ?: 'org.postgresql.Driver'
mergedConfig.password = dsConfig.password ?: ''
mergedConfig.username = dsConfig.username ?: 'postgres'
mergedConfig.url = dsConfig.url ?: 'jdbc:postgresql://localhost:5432/myApp'
And I changed plugin and dependency per Burt's and Emmanuel's advice. And when I run grails db-reverse-engineer command I get this error.
Compilation error: startup failed:
Compile error during compilation with javac.
/home/Documents/Grails_Workspace/myApp/target/work/plugins/cache-1.1.8/src/java/grails/plugin/cache/web/GenericResponseWrapper.java:203: error: method does not override or implement a method from a supertype

^

Note: Some input files use unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
What are those errors mean and how can I get rid of it?
Thanks.

You've got the same plugin set up twice:
compile 'org.grails.plugins:db-reverse-engineer:4.0.0'
runtime ':db-reverse-engineer:4.0.0'
According to the plugin's page it should be configured as a compile time dependency:
compile "org.grails.plugins:db-reverse-engineer:4.0.0"
The plugin does have the command that's claimed to be missing. You can see it here. So you may need to refresh the dependencies by running:
grails refresh-dependencies
