Eclipse下使用Ant

目前的Eclipse都集成了ant,本文图示如何在eclipse下使用ant。
1.新建Java Project-新建Java文件HelloWorld.java
HelloWorld.java
package example;
publicclass HelloWorld {
    publicstaticvoid main(String[] args) {
       System. out .println( "Hello World" );
    }
}
 
2.在工程根目录下新建build.xml
build.xml
default= "main" basedir= "." >
    name= "main" depends= "compile, compress" description= "Main target" >
       Building the .jar file.
   
    name= "compile" description= "Compilation target" >
       srcdir= "${basedir}/src/example" />
   
    name= "compress" description= "Compression target" >
       jarfile= "HelloWorld.jar" basedir= "${basedir}/src/example" includes= "*.class" />
   
此脚本文件内容是编译/src/example下的java文件,并就地生成class文件,将这个class文件打成jar包,HelloWorld.jar。
此时工程的目录结构如下图所示:
右键选中HelloAnt工程,选择Properties:
选择Builders-New…,选择Ant Build,
Name:Ant_Builder;
Buildfile:${workspace_loc:/HelloAnt/build.xml};
Base Directory:${workspace_loc:/HelloAnt};
(按“Browse Workspace”选择工程根目录)
在Builder面板中钩上Ant_Build,去掉Java Builder,即可编译执行。
每次编译时,右键build.xml,选择Run As-Ant Build:
此示例工程编译结果:
Buildfile: D:\dev\Workspaces\J2EE\HelloAnt\build.xml
compile :
compress :
main :
     [ echo ] Building the .jar file.
BUILD SUCCESSFUL
Total time: 281 milliseconds
