jsp - 使用gradle构建运行tomcat jasper任务(jspc)

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:

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

}

异常(exception)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？

最佳答案

可以使用包含类catalina-tasks.xml的Tomcat JAR文件代替使用Tomcat的bin目录中的org.apache.jasper.JspC。如果您的JSP编译缺少任何库，则可以轻松地将它们添加到配置jasper中。

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")
}
