[ANT]属性和类路径引用继承在“foreach"中被破坏

问题描述

为了简单解释，这里是一个例子:

To explain it briefly, here is an example:

在 build.xml 中，导入了 local-db.xml.在 local-db.xml 中，有一个名为warmup"的目标，它使用任务调用第三个文件的一个目标——local-gr.xml.

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.

所有公共属性和类路径定义都在 build.xml 中导入和设置.

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

在 project.properties 中:

in project.properties:

dest-dir=./destination

在 build.xml 中:

in build.xml:

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

在 local-db.xml 中:

in local-db.xml:

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

在 local-gr.xml 中，有两个这样的目标:

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>

问题来了:

属性${dest-dir}和路径gr-classpath"可以在deploy"中使用，因为我设置了inheritAll和inheritRefs，但不能在deploy-single"中直接使用.当目标被 foreach 调用时，继承"不会?

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?

在 的帮助下，我设法将 ${dest-dir} 传递给deploy-single"，但我没有找到任何方法将类路径引用gr-classpath"传递给deploy-single".

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".

我为解决这个问题所做的是在deploy-single"中再次声明，但我根本不喜欢它.

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

为什么会这样?我该怎么做才能让它更优雅?

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

推荐答案

ant-contrib foreach 任务 默认情况下不会传播对其目标的所有属性和引用.但它确实具有 inheritall 和 inheritrefs 属性，您可以使用它们来实现这一点.

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"
/>
