ant中宏定义例子

<!----> 一个ant中用于编译的宏定义例子：
 1       < macrodef name = " compile " >
 2           < attribute name = " module " />
 3           < attribute name = " additional.src.dirs "   default = "" />
 4           < element name = " options "  optional = " yes " />
 5 
 6           < sequential >
 7               < echo > Compiling @{module} </ echo >
 8               < mkdir dir = " ${build.dir}/@{module}/classes " />
 9               < mkdir dir = " ${test.dir}/@{module}/classes " />
10               < javac srcdir = " ${src}/@{module};@{additional.src.dirs} "
11                  destdir = " ${build.dir}/@{module}/classes "  debug = " ${compile.debug} "
12                  deprecation = " ${compile.deprecation} "  optimize = " ${compile.optimize} "
13                  classpathref = " @{module}.compile.classpath " >
14                   < options />
15               </ javac >
16               < javac srcdir = " test/@{module} "  debug = " true "
17                  destdir = " ${test.dir}/@{module}/classes " >
18                   < classpath >
19                       < path refid = " @{module}.test.classpath " />
20                       < path location = " ${build.dir}/@{module}/classes " />
21                   </ classpath >
22                   < options />
23               </ javac >
24           </ sequential >
25       </ macrodef >

   调用宏代码： 

<!----> 1、 < compile module = " web "  additional.src.dirs = " ${build.dir}/web/gen " />
2、<compile module="dao"/>
