Answer 1

The Ant jars are available in run-app because they're needed to run the scripts. But the jars aren't included in a war because in general Ant isn't used by the web app. But you can include them by declaring a dependency in grails-app/conf/BuildConfig.groovy:

dependencies {
   compile 'org.apache.ant:ant:1.7.1'
   compile 'org.apache.ant:ant-launcher:1.7.1'
}
