[ANT]物业及Classpathref继承＆QUOT破裂;的foreach＆QUOT; [英] [ANT]Property and Classpathref inherit broken in "foreach"

问题描述

要简单介绍一下吧，这里有一个例子：

To explain it briefly, here is an example:

在build.xml文件，本地db.xml是进口的。而在本地db.xml，有一个名为热身的目标这就要求第三个文件的一个目标 - 本地gr.xml使用任务

In build.xml, local-db.xml is imported. And in local-db.xml, there is a target named "warmup" which calls one target of the third file -- local-gr.xml using task.

所有的公共属性和CLASSPATH DEFS都是进口的，并在build.xml文件设置。

All the common properties and classpath defs are imported and set in build.xml.

在project.properties：

in project.properties:

dest-dir=./destination

在build.xml文件：

in build.xml:

<path id="gr-classpath"> ... </path>
<import file="local-db.xml" />

在当地db.xml：

<ant antfile="local-gr.xml" target="deploy" inheritAll="true" inheritRefs="true" />

在本地gr.xml，有这样两个目标：

In local-gr.xml, there are two targets like this:

<target name="deploy">
    <tar ....../>
    <foreach list="${list1}" delimiter="," parallel="true" trim="true" param="item" target="deploy-single" />
</target>

<target name="deploy-single">
    something using property ${dest-dir} and path "gr-classpath"
</target>

现在这里的问题是：

属性$ {DEST-DIR}和路径GR-类路径可在部署，因为我设置inheritAll和inheritRefs可以使用，但它不能在部署单直接使用。 继承不会当目标被称为的foreach？

The property ${dest-dir} and path "gr-classpath" can be used in "deploy" because I set inheritAll and inheritRefs, but it can't be used directly in "deploy-single". "inherit" doesn't when the target is called by foreach?

我设法通过$ {DEST-DIR}为部署单用的帮助，但我没有找到任何方式来传递classpathrefGR-类路径，以部署单。

I managed to pass ${dest-dir} to "deploy-single" with the help of the , but I didn't find any way to pass the classpathref "gr-classpath" to "deploy-single".

我做了什么来解决它在部署单再次声明了，但我不喜欢它。

What I did to work around it was to claim the again in "deploy-single", but I don't like it at all.

为什么出现这种情况？我能做些什么，使之更优雅？

Why this happens? What can I do to make it more elegant?

推荐答案

借助蚂蚁-contrib 的foreach 任务默认情况下不传播所有属性和引用它的目标。但它确实有 inheritall 和 inheritrefs 属性，您可以使用来实现这一目标。

The ant-contrib foreach task doesn't by default propagate all properties and references to it's target. But it does have inheritall and inheritrefs attributes that you can use to make that happen.

<foreach list="${list1}" delimiter="," parallel="true" trim="true"
         param="item" target="deploy-single"
         inheritall="true" inheritrefs="true"
/>
