使用gradle build运行tomcat jasper任务jspc

如何解决使用gradle build运行tomcat jasper任务jspc

|| 我正在尝试在gradle中使用jspc编译我们的jsp文件，但遇到了异常。 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：

}

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？     

解决方法

可以使用包含类

org.apache.jasper.JspC

的Tomcat JAR文件代替使用Tomcat \

bin

目录中的

catalina-tasks.xml

。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ѭ8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\")
}
