Where is the dependency to the jar file being set? - grails

Question

Sorry Grails noob here.
I am looking at a project which has some references to JUnit in its test code. I am trying to figure out how JUnit is being added to the classpath. I go to the BuildConfig.groovy file and I see no explicit reference to JUnit.
The dependencies are:
dependencies {
// specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes eg.
test "org.spockframework:spock-grails-support:0.7-groovy-2.0"
runtime 'postgresql:postgresql:9.0-801.jdbc4'
compile 'com.thoughtworks.xstream:xstream:1.4.2'
compile 'spy:spymemcached:2.8.9'
compile "org.grails:grails-webflow:$grailsVersion"
compile 'org.infinispan:infinispan-core:5.1.0.CR2'
}
The plugin dependencies are:
plugins {
test(":spock:0.7") {
exclude "spock-grails-support"
}
runtime ":jquery:1.7.2"
runtime ":resources:1.1.6"
// Uncomment these (or add new ones) to enable additional resources capabilities
//runtime ":zipped-resources:1.0"
//runtime ":cached-resources:1.0"
//runtime ":yui-minify-resources:0.1.4"
build ":tomcat:$grailsVersion"
compile ":geoip:0.2"
compile ':cache:1.0.0'
compile ":quartz:1.0-RC9"
//compile ":quartz-monitor:0.3-RC2"
compile ":grails-melody:1.45"
compile ':webflow:2.0.0', {
exclude 'grails-webflow'
}
}
So any ideas on what could be bringing in the Junit jar or how I'd find out what it is?
Thanks.

JUnit is part of the grails packaging by default. You should be able to find junit jar in lib of grails bundle which you would have downloaded from grails.org in
GRAILS_HOME\lib\junit\junit\jars
You can also verify how it is added to the project by running grails dependency-report on the project and looking for junit jar in test scope.
The latest version of junit shipped with Grails 2.2.3 is junit-4.10.
