在Eclipse下使用ant
目前的Eclipse都集成了ant,但是如何在Eclipse下使用ant呢?
1.新建Java Project-新建Java文件HelloWorld.java
HelloWorld.java:
package example; public class HelloWorld { public static void main(String[] args) { System.out.println("Hello World"); } }
2.在工程根目录下新建build.xml
build.xml:
<?xml version="1.0" encoding="utf-8"?> <project default="main" basedir="."> <target name="main" depends="compile, compress" description="Main target"> <echo>Building the .jar file.</echo> </target> <target name="compile" description="Compilation target"> <javac srcdir="${basedir}/src/example" /> </target> <target name="compress" description="Compression target"> <jar jarfile="HelloWorld.jar" basedir="${basedir}/src/example"includes="*.class" /> </target> </project>
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:
编译结果:
Buildfile: F:\workfile\ant_test\build.xml compile: [javac] F:\workfile\ant_test\build.xml:7: warning: ‘includeantruntime‘ was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds compress: main: [echo] Building the .jar file. BUILD SUCCESSFUL Total time: 1 second
