Dependency Requirement causes error under Grails 2.0

[OverZealous]

When using this plugin under Grails 2.0.1, it throws an error and fails to run. If I add

compile ":cache-headers:1.0.4 > *"

to my BuildConfig, I actually still get an error. It required me manually adding:

compile ":cache-headers:1.1.5"

To get it to work. Not sure why.

Currently enabled plugins, if this matters:

compile ":spring-security-core:1.2.7.2"
compile ":webxml:1.4.1"
compile ":multi-tenant-single-db:0.8.2"
compile ":fields:1.1"
compile ":database-session:1.1.2"
compile ":quartz:0.4.2"
compile ':heroku:1.0.1'
compile ':cloud-support:1.0.9'
runtime ":hibernate:$grailsVersion"
runtime ":jquery:1.7.1"

runtime ":resources:1.1.6"
//>>>>>>>>>
compile ":cache-headers:1.1.5"

runtime ":mail:1.0"
build ":tomcat:$grailsVersion"
