modifying properties in Environment variables
Increase the------c:\ant\bin before the Path property, so you can use ant
The Build.xml file contains one project and at least one target element, and the target element contains one or more task elements, and the task is an executable code.
The root element is project, three properties Name,default,basedir
Name Specifies the project names
default Specifies the target element for the project
BASEDIR Specifies the base path for the project, if it is ".", which is represented as the path of the Build.xml
<project name= "Bookstore" default= "about" basedir= "." >
<target name= "Init" > <tstamp/>
<!--initialize the names of each variable--> <property name= "Build" value= "builds"/><!--compiled directory--> <property " src "value=" src "/><!--the location of the source files-->
<!--the package--> of the environment variables used
<property environment= "myenv"/> <property name= "Servletpath" value=. Catalina_home}/common/lib/servlet-api.jar "/> <property name= mysqlpath" value= "WEB-INF/lib/mysqldriver.jar" />
<mkdir dir= "${build}"/><!--call the previous directory parameter is ${xxx}--> <mkdir dir= "${build}\web-inf"/> <mkdir "dir=" ${ Build}\web-inf\classes "/>
<copy todir= "${build}" ><!--copy directory files to the new directory--> <fileset dir= "${basedir}" ><!--the original directory is a basedir parameter --> <include name= "*.jsp"/> <include name= "*.bmp"/> <include name= "WEB -inf/** "/> <exclude name= build.xml"/><!--do not copy this file--> </fileset> </copy> </target>
<target name= "Compile" depends= "init" > <!--it relies on the execution of Init, so calling it executes first init-->
<javac srcdir= "${src}" destdir= ${build}/web-inf/classes "classpath=" ${servletpath}:${mysqlpath } "> </javac> </target>
<target name= "Bookstorewar" depends= "compile" > <!--the task of generating the war-->
<war warfile= "${build}/bookstore.war" webxml= "${build}/web-inf/web.xml" > <lib dir= "${build}/WEB-INF/lib"/ > <classes dir= "${build}/web-inf/classes"/> <fileset dir= "${build}"/> </war> </target>
<target name= "About" > <!--default target--> <echo> This build.xml file contains targets fo R Building Bookstore Web application </echo> </target>
</project>
We have this build.xml in the root of our application
So the way to run Ant is: Under DOS
1. Enter C:\MYAPP, our application directory input: Ant (will search the current path of the Build.xml file)
2. Direct Input Ant-buildfile C:\myApp\build.xml
3. Direct input Ant-buildfile c:\myApp\build.xml about
All three of these methods execute the target of about, and if you want to compile the Java file, we just
Ant-buildfile C:\myApp\build.xml Compile
