我如何可以通过两个可变在一个Ant目标由劈裂逗号 [英] How can i pass two variable in one Ant target by spliting commas

问题描述

我有一个 deploy.path1 = A，B，C，D，E 和 deploy.path2 = 1,2,3,4 ，我想同时使用A和1一个目标部署像下面如意味着双方应可在同一时间就好了，1，那么下一次B，2等等...

I have one deploy.path1=A,B,C,D,E and deploy.path2=1,2,3,4 and I want to use A and 1 in one target Deploy like below eg at one time means both should be available at same time like A,1 then next time B,2 and so on...

<target name"deploy">
<echo message="${A}"/>
<echo message="${1}"/>
</target>

我怎样才能做到这一点？

How can i do this?

目前我使用

<foreach list="${deploy.loc2}" param="deploy_javapass" target="copy_patch_javapass" delimiter="," inheritall="true" inheritrefs="true" 
    parallel="false" trim="true"/> 

任务，但以这种方式，我们可以一次只传递一个参数。

task but in this way we can pass only one parameter at one time.

推荐答案

我很少使用蚂蚁的contrib 任务。如果您需要复杂的逻辑，我建议嵌入一个合适的脚本语言，例如常规任务。

I rarely use the ant-contrib tasks. If you need complex logic, I'd suggest embedding a proper scripting language, for example the groovy task.

下面的例子中调用的方式部署任务，你所描述：

The following example invokes the "deploy" task in the manner you've described:

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

    <property name="deploy.path1" value="A,B,C,D,E"/>
    <property name="deploy.path2" value="1,2,3,4,5"/>

    <target name="run">
        <taskdef name="groovy" classname="org.codehaus.groovy.ant.Groovy">
            <classpath>
                <pathelement location="/path/to/groovy/jar/groovy-all-1.8.5.jar"/>
            </classpath>
        </taskdef>

        <groovy>
        def values1 = properties."deploy.path1".split(",")
        def values2 = properties."deploy.path2".split(",")

        values1.eachWithIndex { value1, i ->
            properties.val1 = value1
            properties.val2 = values2[i]

            ant.project.executeTarget('deploy')
        }
        </groovy>
    </target>

    <target name="deploy">
        <echo message="path1 = ${val1}"/>
        <echo message="path2 = ${val2}"/>
    </target>

</project>

用常春藤来管理第三方罐子增强例如

有关新的ANT安装，我增加了一个额外的目标，以构建文件：

Enhanced example using ivy to managed 3rd party jars

For new ANT installations, I added an extra target to the build file:

$ ant install-ivy

通过下载常春藤任务jar包，这将建立常春藤。

This will setup ivy by downloading the ivy task jar.

使用常春藤一个Ant任务结束杀。但是当你使用它来管理你的各种类路径超过不负有心人。

Using ivy for one ANT task is over-kill. However it more than pays off when you use it to manage your various classpaths.

Maven的中央有一个广阔的可供下载的开源库：

Maven central has a vast range of open source libraries available for download:

http://search.maven.org/

<project name="demo" default="run" xmlns:ivy="antlib:org.apache.ivy.ant">

    <property name="deploy.path1" value="A,B,C,D,E"/>
    <property name="deploy.path2" value="1,2,3,4,5"/>

    <target name="install-ivy">
        <mkdir dir="${user.home}/.ant/lib"/>
        <get dest="${user.home}/.ant/lib/ivy.jar" src="http://search.maven.org/remotecontent?filepath=org/apache/ivy/ivy/2.2.0/ivy-2.2.0.jar"/>
    </target>

    <target name="init">
        <ivy:resolve/>
        <ivy:cachepath pathid="build.path" conf="build"/>
    </target>

    <target name="run" depends="init">
        <taskdef name="groovy" classname="org.codehaus.groovy.ant.Groovy" classpathref="build.path"/>

        <groovy>
        def values1 = properties."deploy.path1".split(",")
        def values2 = properties."deploy.path2".split(",")

        values1.eachWithIndex { value1, i ->
            properties.val1 = value1
            properties.val2 = values2[i]

            ant.project.executeTarget('deploy')
        }
        </groovy>
    </target>

    <target name="deploy">
        <echo message="path1 = ${val1}"/>
        <echo message="path2 = ${val2}"/>
    </target>

</project>

的ivy.xml

ivy文件列出了构建的依赖关系：

ivy.xml:

ivy file listing the build's dependencies:

<ivy-module version="2.0">
    <info organisation="myorg" module="mymodule" />
    <configurations>
        <conf name="build" description="Build dependencies"/>
    </configurations>
    <dependencies>
        <dependency org="org.codehaus.groovy" name="groovy-all" rev="1.8.5" conf="build->default"/>
    </dependencies>
</ivy-module>
