For working with ant you need to first set the path of the environment variables.I am going to do this in command prompt by executing the following line in command prompt as follows<\/p>\n
STEP 1<\/strong> STEP 2<\/strong> STEP 3<\/strong> In build.xml is a ANT Script that starts with root node project. What if I named my build file to some other name other than build.xml say build2.xml<\/strong> What if I want to run a different target<\/strong><\/p>\n build2.xml<\/em><\/p>\n You can enforce dependency in ANT script by using depends<\/strong> keyword as in the following script below<\/p>\n When you run the ANT script you will see Target 1 and Target 2 displayed on the Screen.Though the default target is target2 since it depends on target1 both are getting displayed.<\/p>\n If there are two targets which depends on each other then circular dependency will occur<\/p>\n Creating a Folder using build.xml<\/strong><\/p>\n Before you are making a Folder you need to clean it as below<\/p>\n Below is a Simple java project which uses an ANT script and creates three folder build.The build contains classes and jar folder.The compiled class files will sit in classes folder and jar files will sit in jar folder.<\/p>\n Project Java File – Sample.java<\/strong><\/p>\n Once you run an ANT script it does the following task as below Copying folder from one Location to Another<\/strong><\/p>\n The above code copies the content in from WebContent folder to D:\/build\/web<\/strong><\/p>\n Simple Copying of File from one directory to another<\/p>\n Above I am copying a file index.jsp into location D:\/build\/mugil\/ and saving it as index2.jsp<\/p>\n If you want to copy the file and Save it in to directory use the below code<\/p>\n If there is no folder then folder will be created before copying file<\/p>\n Excluding certain type of files while copying<\/strong> The above code excludes XML file in current folder from getting copied.Now what if i want the XML files in the sub folder from getting copied<\/p>\n ** is going to look for files in sub folder and excludes those from getting copied.<\/p>\n How to pack files into Zip<\/strong><\/p>\n The above code creates a Zip file with contents in WebContent <\/p>\n Note<\/strong>: build.properties<\/strong> build.xml<\/strong><\/p>\n OP:1.0<\/p>\n Now I am going to add directory name in build.properties file as below<\/p>\n build.properties<\/strong> The above code creates a folder in D drive with name NewFiles<\/p>\n Why Double Backward slash?<\/strong> Is there any other way I define my folder path?<\/strong> build.properties<\/strong> ANT properties are Immutable<\/strong> build.properties<\/strong> In line 2 I am getting the appversion value set to 1.1. Later I am trying to redefine the same property by setting the value of the attribute to 1.0.But if you print the value using echo statement you can see 1.1 getting printed on console<\/p>\n OP:1.1<\/p>\n Hence ANT Properties are immutable.<\/p>\n Now you want to dynamically make changes in build.properties file on fly.<\/p>\n In build.properties file appversion value is set to 1.1.But by using propertyfile tag i am resetting the value to 1.3.This Change will also be made in the original build.properties file<\/strong>.So next time when you open build.properties you can note the appversion value got changed to 1.3 and time of change as commented text.<\/p>\n","protected":false},"excerpt":{"rendered":" For working with ant you need to first set the path of the environment variables.I am going to do this in command prompt by executing the following line in command prompt as follows STEP 1 I should set the Path for Java Directory and for ant bin directory as above.

\nI should set the Path for Java Directory and for ant bin directory as above.<\/p>\n\r\n C:\\Users\\Mugil>set PATH=D:\\Java\\jdk1.6.0_32\\bin;D:\\Mugil\\apache-ant-1.9.0\\bin;\r\n<\/pre>\n
\nNow I should create a build.xml file which the ant looks for deployment as follows
\nbuild.xml<\/em><\/p>\n\r\n<?xml version="1.0" encoding="UTF-8"?>\r\n<project name="codethataint" default="default target">\r\n <target name="default target">\r\n <echo>\r\n Executing Default Target\r\n <\/echo>\r\n <\/target>\r\n<\/project>\r\n<\/pre>\n
\nTo run the ant file use the following line in command prompt as below<\/p>\n\r\n d:\\Mugil\\staging>ant\r\n<\/pre>\n
\nProject will have set of Targets
\nTargets will have set of Tasks<\/p>\n
\nIn such case you can use the below command as follows<\/p>\n\r\n d:\\Mugil\\staging>ant -buildfile \r\n<\/pre>\n
\r\n<?xml version="1.0" encoding="UTF-8"?>\r\n<project name="codethataint" default="default target">\r\n <target name="default target">\r\n <echo>\r\n Executing Default Target\r\n <\/echo>\r\n <\/target>\r\n <target name="target 2">\r\n <echo>\r\n Target 2 \r\n <\/echo>\r\n <\/target>\r\n<\/project>\r\n<\/pre>\n
\r\n d:\\Mugil\\staging>ant -buildfile "target 2"\r\n<\/pre>\n

\n1.Target Clean<\/strong> – Deletes the folder build
\n2.Target makedir<\/strong> – Creates two directory build and Classes
\n3.Target compile<\/strong> – Compiles code and puts in classes folder as specified in destdir
\n4.Target makejar<\/strong> – Creates the JAR file as specified in the jar tag<\/p>\n\n
\r\n<target name="makecopy">\t\r\n <copy todir="D:\/build\/web">\r\n <fileset dir="WebContent">\r\n <\/fileset> \r\n <\/copy>\r\n<\/target>\r\n<\/pre>\n

\r\n <copy file="WebContent\/index.jsp" todir="D:\/build\/mugil\/"\/>\r\n<\/pre>\n
\nNow I want to exclude certain types of files from get copied say XML files.<\/p>\n\r\n <target name="copyTarget">\r\n <copy todir="D:\/build\/web">\r\n <fileset dir="WebContent">\r\n <exclude name="*.xml"\/>\r\n <\/fileset> \r\n <\/copy>\r\n <\/target>\r\n<\/pre>\n

\r\n<zip destfile="D:\/build\/web\/zip\/Sample.zip">\r\n <fileset dir="WebContent"\/>\r\n<\/zip>\r\n<\/pre>\n
\nNever hard code version numbers and folder location in build.xml as they are constantly updated over a period of time.You can create a separate file where you can put your version numbers and replace it as properties in build.xml file as shown below<\/p>\n
\nappversion=1.0<\/p>\n\r\n <project name="ANT2" default="copyTarget">\r\n <property file="build.properties"\/>\r\n <target name="copyTarget">\r\n \t <echo>${appversion} <\/echo>\r\n <\/target>\r\n <\/project>\r\n<\/pre>\n
\ndest.dir=D:\\\\NewFiles<\/p>\n
\nIf you are not giving double backward slash then it will take absolute path and creates folder in project work space<\/p>\n
\nYes.you can define it by absolute path by using forward slash as below.<\/p>\n
\ndest.dir=D:\/NewFiles<\/p>\n
\nNow consider the below code.<\/p>\n
\nappversion=1.1<\/p>\n\r\n<project name="ANT2" default="copyTarget">\r\n <property file="build.properties"\/>\r\n <property name="appversion" value="1.0"\/>\r\n <target name="copyTarget">\r\n <echo>${appversion} <\/echo>\r\n <\/target>\r\n<\/project>\r\n<\/pre>\n\r\n <project name="ANT2" default="copyTarget">\r\n <property file="build.properties"\/>\r\n <propertyfile file="build.properties" comment="My properties">\r\n <entry key="appversion" value="1.3"\/>\r\n <\/propertyfile>\t\r\n <target name="copyTarget">\r\n <echo>${appversion} <\/echo>\r\n <\/target>\r\n <\/project>\r\n<\/pre>\n
