将单个文件复制到Ant中的多个目录

Question

我想在构建过程中将一个文件复制到多个目录。

${prop.fmt}中的值有两个目录，我只想将一个WAR文件复制到这两个目录中:

/apps/phxadmin-dev/devd/ui_tomcats/tomcat_c345tczuwdvd2/webapps
/apps/phxadmin-dev/devd/ui_tomcats/tomcat_c404gxduwdvd1/webapps

My Ant script:

<target name="test" >
    <dirset id="dir.name" dir="${phx.tomcat.dir}" includes="*/webapps"/>
    <property name="prop.dist.contents" refid="dir.name"/>      
    <loadresource property="prop.fmt">
        <string value="${prop.dist.contents}"/>
        <filterchain>
            <tokenfilter>
                <replaceregex pattern=";" replace="${line.separator}" flags="g"/>
            </tokenfilter>
            <prefixlines prefix="${phx.tomcat.dir}/" />
        </filterchain>
    </loadresource>
    <echo message="${prop.fmt}"/>
    <copy file="${phx.deploy.dir}/${war.file.name}" todir="${prop.fmt}"/>
</target>

请问有人能帮帮我吗?

<copy>任务可以通过以下方式复制到多个目的地:

• 设置enableMultipleMappings属性为true
• 和使用<scriptmapper>

在您的示例中，整个<target name="test">块可以替换为…

<target name="test">
    <dirset id="dir.name" dir="${phx.tomcat.dir}" includes="*/webapps"/>
    <copy todir="${phx.tomcat.dir}" enableMultipleMappings="true" verbose="true">
        <fileset file="${phx.deploy.dir}/${war.file.name}"/>
        <scriptmapper language="javascript">
        <![CDATA[
            var dirSet = project.getReference( "dir.name" );
            var ds = dirSet.getDirectoryScanner( project );
            var includes = ds.getIncludedDirectories( );
            for ( var i = 0; i < includes.length; i++ )
            {
                self.addMappedName( includes[i] + "/" + source );
            }
        ]]>
        </scriptmapper>
    </copy>
</target>

运行上面的脚本会得到如下输出:

test:
     [copy] Copying 1 file to /apps/phxadmin-dev/devd/ui_tomcats
     [copy] Copying my.war to /apps/phxadmin-dev/devd/ui_tomcats/tomcat_c345tczuwdvd2/webapps/my.war
     [copy] Copying my.war to /apps/phxadmin-dev/devd/ui_tomcats/tomcat_c404gxduwdvd1/webapps/my.war
