如何使用Antcontrib SVN蚂蚁.错误原因:名称不确定

Question

我正在尝试使用ant antcontrib，我将jar文件添加到文件夹中，然后使用 pathelement

指向它

        <pathelement location="D:ppppSVN1.8.Clientant-contrib-1.0b3.jar" />

但是使用以下代码i ma获取此错误

build failed
TEST.xml:59: Problem: failed to create task or type trycatch
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.

    <echo message="revision of last commit: ${revision.result}" />
</target>

我添加了它，它起作用

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