Use ant to compile and generate a jar package

Use ant to generate an executable JAR file. Double-click it to open the window.

1. Write a class for creating a window

PackageCom. anllin. Ant. test;   ImportJava. AWT. color; ImportJava. AWT. dimension;   ImportJavax. Swing. jbutton; ImportJavax. Swing. jframe;   Public ClassWindow { Public Static VoidMain (string [] ARGs) { Jframe frame =NewJframe (); Frame. setsize (NewDimension (200,300 )); Frame. setbackground (NewColor (200,200,200 )); Frame. setalwaysontop (True); Frame. getcontentpane (). Add (NewJbutton ("ant ")); Frame. setvisible (True); Frame. setdefaclocloseoperation (jframe.Exit_on_close); } }

 

2. Use ant to compile and generate a jar package

<? XML version = "1.0" encoding = "UTF-8"?> <Project name = "myantproject" basedir = "." default = "package"> <Property name = "compile" value = "compile"/> <Property name = "Dist" value = "Dist"> </property> <Target name = "init"> </Target> <Target name = "preprocess" depends = "init"> <Mkdir dir = "$ {compile}"/> <Mkdir dir = "$ {Dist}"/> </Target> <Target name = "compile" depends = "init, preprocess"> </Target> <Target name = "package" depends = "compile"> </Target> <Target name = "mycompile" depends = "preprocess"> <Javac srcdir = "src" destdir = "$ {compile}"> </javac> </Target> <Target name = "Dist" depends = "mycompile"> <Jar destfile = "$ {Dist}/package.

Window"/> </Manifest> </Jar> </Target> </Project>
