使用cpptask使用ant-contrib编译C程序

Question

这是我的build.xml文件的样子：

<project name="test" xmlns:cpptasks="antlib:net.sf.antcontrib.cpptasks">
    <target name="build-native">
        <mkdir dir="/home/varun/Desktop/lucene/3018-test/check"/>
        <cpptasks:cc outtype="executable" subsystem="console" outfile="BuildNativeDir" objdir="/home/varun/Desktop/lucene/3018-test">
           <fileset file="/home/varun/Desktop/lucene/3018-test/hello.c" />
        </cpptasks:cc>
    </target>
</project>

当我运行命令ant build-native时，我得到一个错误：

BUILD FAILED
/home/varun/Desktop/lucene/3018-test/build.xml:4: Problem: failed to create task or type antlib:net.sf.antcontrib.cpptasks:cc
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.
No types or tasks have been defined in this namespace yet

This appears to be an antlib declaration. 
Action: Check that the implementing library exists in one of:
        -/usr/share/ant/lib
        -/home/varun/.ant/lib
        -a directory added on the command line with the -lib argument


Total time: 0 seconds

但我的CLASSPATH设置为/usr/share/ant/lib，并且我已将ant-contrib-1.0b3.jar放在/usr/share/ant/lib/ant-contrib-1.0b3.jar中。

我做错了什么？

ant-contrib-*.jar中不包含cpptask。您必须单独对其执行download。

我刚试过cpptasks-1.0-beta5，但它不能编译。cpptasks-1.0-beta4在归档文件中有一个预编译的jar，它工作得很好。
