Running tomcat jasper task (jspc) with gradle build

I'm trying to compile our jsp files using jspc within gradle but am getting an exception.

Here is the pertinent gradle section

//tomcatHome is defined in gradle.properties
ant.tomcatHome = "${tomcatHome}"
ant.webAppDir = "${webAppDir}"
ant.importBuild 'jspc.xml'
test.dependsOn jspc

And the jspc.xml ant file

<?xml version="1.0"?>

<project name="jspc" basedir="." default="jspc">
  <!-- Import tasks from Tomcat -->
  <import file="${tomcatHome}/bin/catalina-tasks.xml" />

  <target name="jspc">
    <jasper validateXml="false" uriroot="${webAppDir}" />
  </target>
</project>

The repositories section:

repositories {
  mavenRepo urls: 'http://repository.jboss.org/nexus/content/groups/public-jboss'
  mavenRepo urls: 'http://oss.sonatype.org/content/repositories/sourceforge-releases'
  mavenRepo urls: 'http://google-gson.googlecode.com/svn/mavenrepo'
  mavenCentral()
}

The dependencies section:

The exception is:

Any ideas?

Instead of using catalina-tasks.xml from Tomcat's bin directory you can use the Tomcat JAR file that includes the class org.apache.jasper.JspC instead. If there are any libraries missing for your JSP compilation you can easily add them to the configuration jasper.

configurations {
    jasper
}

repositories {
    mavenCentral()
}

dependencies {
    jasper 'org.apache.tomcat:jasper:6.0.33',
           'javax.servlet:jstl:1.1.2',
           'taglibs:standard:1.1.2'
}

test.doLast {
    ant.taskdef(classname: 'org.apache.jasper.JspC', name: 'jasper', classpath: configurations.jasper.asPath)
    ant.jasper(validateXml: false, uriRoot: webAppDir, outputDir: "$buildDir/jspc")
}
