In this page, I will show you some of basic ant command that might be useful for application compile and deployment.

Assumption and Background

• Apache Ant should be installed and evironment path is set correctly.

Ant Build Files

• Let’s create a file and name it as “build.xml”

<?xml version = "1.0" encoding="utf-8"?>
<project name = "Hello World Project" default = "compile" basedir="/var/lib/jenkins/workspace/src">
   <target name = "info">
      <echo>Hello World - Welcome to Apache Ant!</echo>
   </target>
</project>

Define Properties within the build file

<?xml version = "1.0" encoding="utf-8"?>
<project name = "Hello World Project" default = "compile" basedir="/var/lib/jenkins/workspace/src">
        <property environment="env"/>
        <property name="src.dir" value="${basedir}" />
        <property name="webcom.dir" value="/was/upwas/WebApp/WEBCOMMON/lib" />
        <property name="common.dir" value="/was/upwas/WebApp/COMMON/lib" />
        <property name="portal.dir" value="/was/upwas/WebApp/MyApplication" />
        <property name="classes.dir" value="/was/upwas/WebApp/MyApplication/WEB-INF/classes" />
        <property name="lib.dir" value="/was/upwas/WebApp/MyApplication/WEB-INF/lib" />
        <property name="ejb.dir" value="/was/upwas/src/ejb/MyApplication" />
        <property name="weblogic.module.dir" value="/was/weblogic1036/modules" />
        <property name="jenkins.ejb.dir" value="/var/lib/jenkins/workspace/MyApplication/src/com/nate/webadmin/ejb" />
        <property name="jenkins.web.dir" value="/var/lib/jenkins/workspace/MyApplication/WebContent" />
        <property name="web.dir" value="/web/apache2.2.31/htdocs/MyApplication" />
   <target name = "info">
      <echo>Hello World - Welcome to Apache Ant!</echo>
   </target>
</project>

Now add a new target compileClass that compiles java files

• This target has a task called “javac” which will compile java source code into class file.
• I added “classpath” attribute within javac task to define classpath during compilation process.
• To add external jar files, I used fileset attribute to define where those jar files are located.

<?xml version = "1.0" encoding="utf-8"?>
<project name = "Hello World Project" default = "compile" basedir="/var/lib/jenkins/workspace/src">
    <property environment="env"/>
    <property name="src.dir" value="${basedir}" />
    ...

    <target name = "info">
        <echo>Hello World - Welcome to Apache Ant!</echo>
    </target>

    <target name="compileClass" >
        <echo message="==========================="/>
        <echo message="  Compile Java Files Start "/>
        <echo message="==========================="/>       
        <javac srcdir="${src.dir}" destdir="${classes.dir}" encoding="euc-kr">
            <include name="**/*.java"/>
            <exclude name="**/*Bean.java"/>
            <classpath>
                <pathelement path="${classes.dir}" />
                <fileset dir="${lib.dir}">
                        <include name="**/*.jar"/>
                </fileset>
                <fileset dir="${webcom.dir}">
                        <include name="**/*.jar"/>
                </fileset>
                <fileset dir="${weblogic.module.dir}">
                        <include name="**/*.jar"/>
                </fileset>
            </classpath>
        </javac>
        <echo message="==========================="/>
        <echo message="  Compile Java Files End   "/>
        <echo message="==========================="/>               
    </target>

</project>

Add another target deleteClass which deletes class files

• This target has a task called “delete” which is quite straight forward.
• It will delete files within the “dir” path

<?xml version = "1.0" encoding="utf-8"?>
<project name = "Hello World Project" default = "compile" basedir="/var/lib/jenkins/workspace/src">
    <property environment="env"/>
    <property name="src.dir" value="${basedir}" />
    ...

    <target name = "info">
        <echo>Hello World - Welcome to Apache Ant!</echo>
    </target>

    <target name="deleteClass" >
        <echo message="==========================="/>
        <echo message="  Delete Class Files       "/>
        <echo message="==========================="/>
        <delete dir="${classes.dir}/com" />
    </target>   

    <target name="compileClass" >
        <echo message="==========================="/>
        <echo message="  Compile Java Files Start "/>
        <echo message="==========================="/>       
        <javac srcdir="${src.dir}" destdir="${classes.dir}" encoding="euc-kr">
            <include name="**/*.java"/>
            <exclude name="**/*Bean.java"/>
            <classpath>
                <pathelement path="${classes.dir}" />
                <fileset dir="${lib.dir}">
                        <include name="**/*.jar"/>
                </fileset>
                <fileset dir="${webcom.dir}">
                        <include name="**/*.jar"/>
                </fileset>
                <fileset dir="${weblogic.module.dir}">
                        <include name="**/*.jar"/>
                </fileset>
            </classpath>
        </javac>
        <echo message="==========================="/>
        <echo message="  Compile Java Files End   "/>
        <echo message="==========================="/>               
    </target>

</project>

Add another target deleteWeb which deletes static files

• Very similar with deleteClass task, except I specified types of file that I want to delete within the target directory “dir”.

<?xml version = "1.0" encoding="utf-8"?>
<project name = "Hello World Project" default = "compile" basedir="/var/lib/jenkins/workspace/src">
    <property environment="env"/>
    <property name="src.dir" value="${basedir}" />
    ...

    <target name = "info">
        <echo>Hello World - Welcome to Apache Ant!</echo>
    </target>

    <target name="deleteWeb" >
        <echo message="============================="/>
        <echo message="  Delete Static Files Start  "/>
        <echo message="============================="/>
        <delete>
            <fileset dir="${web.dir}">
                <include name="**/*.html"/>
                <include name="**/css/**"/>
                <include name="**/guide/**"/>
                <include name="**/images/**"/>
                <include name="**/js/**"/>
                <include name="**/robots.txt"/>
            </fileset>
        </delete>
        <echo message="============================="/>
        <echo message="  Delete Static Files End    "/>
        <echo message="============================="/>
    </target>   

    <target name="deleteClass" >
        <echo message="==========================="/>
        <echo message="  Delete Class Files       "/>
        <echo message="==========================="/>
        <delete dir="${classes.dir}/com" />
    </target>   

    <target name="compileClass" >
        <echo message="==========================="/>
        <echo message="  Compile Java Files Start "/>
        <echo message="==========================="/>       
        <javac srcdir="${src.dir}" destdir="${classes.dir}" encoding="euc-kr">
            <include name="**/*.java"/>
            <exclude name="**/*Bean.java"/>
            <classpath>
                <pathelement path="${classes.dir}" />
                <fileset dir="${lib.dir}">
                        <include name="**/*.jar"/>
                </fileset>
                <fileset dir="${webcom.dir}">
                        <include name="**/*.jar"/>
                </fileset>
                <fileset dir="${weblogic.module.dir}">
                        <include name="**/*.jar"/>
                </fileset>
            </classpath>
        </javac>
        <echo message="==========================="/>
        <echo message="  Compile Java Files End   "/>
        <echo message="==========================="/>               
    </target>

</project>

Add another target copyWeb which copies static files

• This target has a task called “copy” which will copy files into destination folder “todir”
• You can use fileset attribute to specify types of file to copy from “dir”

<?xml version = "1.0" encoding="utf-8"?>
<project name = "Hello World Project" default = "compile" basedir="/var/lib/jenkins/workspace/src">
    <property environment="env"/>
    <property name="src.dir" value="${basedir}" />
    ...

    <target name = "info">
        <echo>Hello World - Welcome to Apache Ant!</echo>
    </target>

    <target name="deleteWeb" >
        <echo message="============================="/>
        <echo message="  Delete Static Files Start  "/>
        <echo message="============================="/>
        <delete>
            <fileset dir="${web.dir}">
                <include name="**/*.html"/>
                <include name="**/css/**"/>
                <include name="**/guide/**"/>
                <include name="**/images/**"/>
                <include name="**/js/**"/>
                <include name="**/robots.txt"/>
            </fileset>
        </delete>
        <echo message="============================="/>
        <echo message="  Delete Static Files End    "/>
        <echo message="============================="/>
    </target>   

    <target name="copyWeb" >
        <echo message="==========================="/>
        <echo message="  Copy Static Files Start  "/>
        <echo message="==========================="/>
        <copy todir="${web.dir}">
            <fileset dir="${jenkins.web.dir}">
                <include name="**/*.html"/>
                <include name="**/css/**"/>
                <include name="**/guide/**"/>
                <include name="**/images/**"/>

            </fileset>
        </copy>
        <echo message="==========================="/>
        <echo message="  Copy Static Files End    "/>
        <echo message="==========================="/>
    </target>    

    <target name="deleteClass" >
        <echo message="==========================="/>
        <echo message="  Delete Class Files       "/>

In case someon wish to use bash command within ant file take a look at this sample compileEJB

• I used exec task to run bash command. To run find command, I used dir and inputstring.
• This sample maybe to simple. It would be a lot easier if you can run the bash script.
• This is just a demo to show that it is possible to run bash command within ant script.
• I also added and task to run another ant file that is located in same folder.
• Make user you use “target” attribute to specify what target you wish to run for the given “antfile”

<?xml version = "1.0" encoding="utf-8"?>
<project name = "Hello World Project" default = "compile" basedir="/var/lib/jenkins/workspace/src">
    <property environment="env"/>
    <property name="src.dir" value="${basedir}" />
    ...

    <target name = "info">
        <echo>Hello World - Welcome to Apache Ant!</echo>
    </target>
    ...

    <target name="compileEJB">
        <exec executable="bash" dir="${ejb.dir}" inputstring="find -type f -name *.java | wc -l" outputproperty="ejb.java.count"/>
        <echo message="==========================="/>
        <echo message=" EBJ File Counts = ${ejb.java.count} "/>
        <echo message="==========================="/>

        <echo message="==========================="/>
        <echo message="  TestBean Start  "/>
        <echo message="==========================="/>
        <ant antfile="Test_build.xml" target="all"/>
        <echo message="==========================="/>
        <echo message="  TestBean End  "/>
        <echo message="==========================="/>
    </target>   

</project>
