我正在尝试在gradle中使用jspc来编译我们的jsp文件，但是却遇到了异常。

这是相关的gradle部分

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

和jspc.xml ant文件

<?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>

存储库部分：

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()
}

依赖项部分：

dependencies {

  springVersion = '3.0.4.RELEASE'
  securityVersion = '3.0.5.RELEASE'

}

例外是：

Cause: file:myfile.jsp(1,1) The absolute uri: <http://java.sun.com/jsp/jstl/core> cannot be resolved in either web.xml or the jar files deployed with this application

有任何想法吗？
