Question

我想在构建项目时使用google-closure-compiler进行javascript和css缩小。已根据要求准备build.xml。

请在下面找到build.xml：

<project name="ITV" default="run">

    <property name="webroot" value="webapp/scripts" />  
    <!--<target name="doMinification" />-->

    <tstamp>
        <format property="TODAY_MY" pattern="yyyyMMdd-HHmmss"  locale="en,UK" />
    </tstamp>

    <taskdef name="jscomp" classname="com.google.javascript.jscomp.ant.CompileTask" classpath="compiler.jar"/>
    <taskdef resource="net/sf/antcontrib/antcontrib.properties">
        <classpath>
            <pathelement location="ant-contrib-1.0b3.jar"/>
        </classpath>
    </taskdef>

    <!-- ================================================================== -->

    <target name="run">
        <foreach target="doMinification" param="foreach.file">
            <path id="jsFileset">
                <fileset id="jsFiles" dir="${webroot}/">
                    <exclude name="**/Libraries/**" />                
                    <include name="**/*.js"/>                   
                </fileset>
            </path>
        </foreach>
    </target>

    <!-- Minify JS -->  
    <target name="doMinification">

        <!-- This gets the filename without the directory path. -->
        <basename property="jsFileName" file="${foreach.file}"/>

        <!-- Using Javascript functions to work out the paths -->
        <script language="javascript"> <![CDATA[

            // get values
            fullPath = project.getProperty("foreach.file");
            fileOnly = project.getProperty("jsFileName");
            fileName = fileOnly.substr(0,fileOnly.lastIndexOf('.'));

            pathOnly = fullPath.substring(0, fullPath.indexOf(fileOnly));

            // store the result in a new property
            project.setProperty("directory",pathOnly);
            project.setProperty("fileName", fileName);

        ]]> </script>

        <!--<echo message="Compressing file ${jsFileName} in ${directory}" />
        <echo message="file only ${fileName}" />-->

        <jscomp compilationLevel="whitespace" warning="verbose" debug="true" languagein="ECMASCRIPT5" output="${directory}\${fileName}-min.js" forceRecompile="true">
            <externs dir="${webroot}/Libraries/Angular/">
                <file name="angular.min.js"/>
            </externs>
            <sources dir="${directory}">
                <file name="${jsFileName}"/>
            </sources>
        </jscomp>

    </target>

</project>

现在，当我执行ant命令时，它会根据脚本启动缩小过程。它适用于少量文件，并突然在此过程中的某个时间点停止。等待一段时间后，将在命令提示符下打印以下消息。

#

我尝试使用ant多次，但每次出现此类消息并且jvm都会崩溃。

可能是什么原因以及如何解决？我的构建脚本有任何问题吗？
