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>
当我运行命令时ant build-native
出现错误:
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
但是我的CLASSPATH
设置为/usr/share/ant/lib
并且我已将ant-contrib-1.0b3.jar
./usr/share/ant/lib/ant-contrib-1.0b3.jar
我究竟做错了什么?
