我如何通过参数传递给一个Ant任务？ [英] How do I pass an argument to an Ant task?

问题描述

我不是很好的蚂蚁，但我们使用它作为构建工具。现在，我们可以运行蚂蚁测试，它会通过所有的单元测试运行。

I'm not very good with Ant, but we're using it as a build tool. Right now, we can run "ant test" and it'll run through all the unit tests.

不过，我很想能够做到像蚂蚁测试some_module ，并让它接受 some_module 作为一个参数，并且只测试

However, I'd love to be able to do something like ant test some_module and have it accept some_module as a parameter, and only test that.

我一直没能找到如何命令行参数传递到Ant - ？任何想法

I haven't been able to find how to pass command line args to Ant - any ideas?

推荐答案

一个解决方法可能如下。 （我有一个项目，做到这一点。）

One solution might be as follows. (I have a project that does this.)

有类似测试一个单独的目标一个文件集，限制测试只有一个类。然后通过使用这个类的名称 -D 在蚂蚁命令行：

Have a separate target similar to test with a fileset that restricts the test to one class only. Then pass the name of that class using -D at the ant command line:

ant -Dtest.module=MyClassUnderTest single_test

在build.xml文件（高度降低）：

In the build.xml (highly reduced):

<target name="single_test" depends="compile" description="Run one unit test">
    <junit>
        <batchtest>
            <fileset dir="${test.dir}" includes="**/${test.module}.class" />
        </batchtest>
    </junit>
</target>
