Oops! Ant quick start 2 ! - ant compile

Oops! Ant quick start 2 ! - ant compile

1.接上文，在javademo下面新建文件 build.xml

< project >

     < target  name ="clean" >
         < delete  dir ="build" />
     </ target >

     < target  name ="compile" >
         < mkdir  dir ="build/classes" />
         < javac  srcdir ="src"  destdir ="build/classes" />
     </ target >

     < target  name ="jar" >
         < mkdir  dir ="build/jar" />
         < jar  destfile ="build/jar/HelloWorld.jar"  basedir ="build/classes" >
             < manifest >
                 < attribute  name ="Main-Class"  value ="oata.HelloWorld" />
             </ manifest >
         </ jar >
     </ target >

     < target  name ="run" >
         < java  jar ="build/jar/HelloWorld.jar"  fork ="true" />
     </ target >

</ project >

2.运行：
ant compile
ant jar
ant run
看到结果

注意：要在系统环境里面设置PATH到ant的bin目录

3.更加简便的打包：修改build.xml，为：

< project  name ="HelloWorld"  basedir ="."  default ="main" >

     < property  name ="src.dir"      value ="src" />

     < property  name ="build.dir"    value ="build" />
     < property  name ="classes.dir"  value ="${build.dir}/classes" />
     < property  name ="jar.dir"      value ="${build.dir}/jar" />

     < property  name ="main-class"   value ="oata.HelloWorld" />



     < target  name ="clean" >
         < delete  dir ="${build.dir}" />
     </ target >

     < target  name ="compile" >
         < mkdir  dir ="${classes.dir}" />
         < javac  srcdir ="${src.dir}"  destdir ="${classes.dir}" />
     </ target >

     < target  name ="jar"  depends ="compile" >
         < mkdir  dir ="${jar.dir}" />
         < jar  destfile ="${jar.dir}/${ant.project.name}.jar"  basedir ="${classes.dir}" >
             < manifest >
                 < attribute  name ="Main-Class"  value ="${main-class}" />
             </ manifest >
         </ jar >
     </ target >

     < target  name ="run"  depends ="jar" >
         < java  jar ="${jar.dir}/${ant.project.name}.jar"  fork ="true" />
     </ target >

     < target  name ="clean-build"  depends ="clean,jar" />

     < target  name ="main"  depends ="clean,run" />

</ project >
