Apache Ant的不承认'的'任务/微距，虽然我已经通过添加的taskdef蚂蚁的contrib [英] Apache ant does not recognize 'for' task/macro, although I have added ant-contrib via taskdef

问题描述

我收到以下，而这样做Ant构建：

I am getting following while doing ant build:

Build\build.xml:247: Problem: failed to create task or type
for
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.

的build.xml行247 ＆lt;用于参数=文件＆GT;

已经定义的＆LT;的taskdef资源=网/ SF / antcontrib / antcontrib.properties/＆GT; ，它没有工作。然后，我特意加入以下但它仍然没有工作。

Already defined <taskdef resource="net/sf/antcontrib/antcontrib.properties"/>, it didn't work. Then I specifically added following but it is still not working.

<taskdef resource="net/sf/antcontrib/antcontrib.properties">
        <classpath>
            <pathelement location="${env.ANT_HOME}/lib/ant-contrib-1.0b3.jar"/>
        </classpath>
    </taskdef>

我的蚂蚁的contrib-1.0b3.jar 在 C：\\软件\\ Apache的ANT-1.8.4 \\ lib中目录。
缺少什么吗？

I have ant-contrib-1.0b3.jar at C:\Softwares\apache-ant-1.8.4\lib directory.
What is missing here?

推荐答案

如果您放置在 $ ANT_HOME / lib目录AntContrib罐子，你真正需要做的是这样的：

If you placed the AntContrib jar in $ANT_HOME/lib directory, all you really need to do is this:

<taskdef resource="net/sf/antcontrib/antcontrib.properties"/>

实际上使用＆lt;用于/＆GT; 任务，你需要做的是：

<taskdef resource="net/sf/antcontrib/antlib.xml"/>

请注意，你必须使用 antlib.xml ，而不是 antcontrib.properties 。 仔细阅读安装方向。这很容易错过。

Note you have to use antlib.xml and not antcontrib.properties. Read the Installation directions very carefully. It's easy to miss.

如果您在团体项目这样做，我建议你把你的蚂蚁contrib.jar在项目中。然后将它们添加到您的项目在你的版本控制系统。这样一来，其他开发人员可以使用你的构建与蚂蚁的contrib任务，而无需下载蚂蚁contrib请罐，并在其$ ANT_HOME目录中安装它自己。

If you are doing this in a group project, I recommend that you put your ant-contrib.jar in your project. THen add them to your project in your version control system. That way, other developers can use your build with the ant-contrib tasks without downloading the ant-contrib jar and installing it in their $ANT_HOME directory themselves.

让我们说你创建一个名为蚂蚁contrib.dir ，并把在你的项目的根目录，然后把蚂蚁contrib请罐的文件夹中。只要把这个项目中的：

Let's say you create a directory called ant-contrib.dir and put that in the root of your project, then put the ant-contrib jar in that folder. Just put this in your project:

<taskdef resource="net/sf/antcontrib/antlib.xml">
    <classpath>
          <fileset dir="${basedir}/ant-contrib.dir"/>
    </classpath>
</taskdef>
