自動建立與螞蟻
概觀:
在本文中，我們將討論有關構建工具Ant和使用這個我們如何可以自動執行基於Java應用程序的構建機制. 在當今時代，螞蟻已經成為Java開發的一個組成部分. 大多數客戶喜歡有自動構建腳本交付源代碼的一部分. 這樣做的原因是由螞蟻提供，使得任何人用一點腳本知識可以產生一個可部署的二進制不知道詳細的應用的簡單性.
介紹:
Apache ant is a generic build tool. 縮寫形式“的另一個巧妙的工具”這個名字ANT看台. 此工具類似於UNIX的'製作'工具，但使用Java實現. 它主要用於構建一個基於Java的源代碼，二進制文件，並部署生成的二進制這是預定義的應用程序服務器. It can also be used to generate javadocs for a code base and to execute the unit test suite for the whole codebase. Ant in collaboration with JUNIT helps developer to follow the test driven development approach.
Ant requires Java compiler to be installed having the environment variable JAVA_HOME set with its adequate value. Ant uses an XML file to define the build procedure. 此文件的默認名稱為build.xml文件. 一些開發商也使用一個屬性文件即build.properties定義一些特性例如. the build version number and other environmental parameters which are required to change from time to time based on the need.
Installation:
FEDORA: On RHEL, ANT can be installed using the command – yum install ant or it can be installed using the rpm – i command. In this case you should download the ant package first.
DEBIAN: On Ubuntu, ANT can be installed using the command – apt-get install ant.
Windows: On windows environment we need to download the ant_<VERSION_NO>.zip file. This zip bundle should be extracted in a folder. This folder should be defined as an environment variable ANT_HOME.
A sample build.xml file is shown as under:
LISTING 1: Sample build.xml file
[Code]
<?xml version=”1.0″?>
<project name=”Ant-Test” default=”主” basedir=”.”>
<!– Sets variables which can later be used. –>
<!– The value of a property is accessed via ${} –>
<property name=”src.dir” location=”src” />
<property name=”build.dir” location=”bin” />
<property name=”dist.dir” location=”dist” />
<property name=”docs.dir” location=”docs” />
<!– Deletes the existing build, docs and dist directory–>
<target name=”clean”>
<delete dir=”${build.dir}” />
<delete dir=”${docs.dir}” />
<delete dir=”${dist.dir}” />
</target>
<!– Creates the build, docs and dist directory–>
<target name=”makedir”>
<mkdir dir=”${build.dir}” />
<mkdir dir=”${docs.dir}” />
<mkdir dir=”${dist.dir}” />
</target>
<!– Compiles the java code (including the usage of library for JUnit –>
<target name=”compile” depends=”clean, makedir”>
<javac srcdir=”${src.dir}” destdir=”${build.dir}”>
</javac>
</target>
<!– Creates Javadoc –>
<target name=”docs” depends=”compile”>
<javadoc packagenames=”src” sourcepath=”${src.dir}” destdir=”${docs.dir}”>
<!– Define which files / directory should get included, we include all –>
<fileset dir=”${src.dir}”>
<include name=”**” />
</fileset>
</javadoc>
</target>
<!–Creates the deployable jar file –>
<target name=”jar” depends=”compile”>
<jar destfile=”${dist.dir}\in.kolkalta.build.test.ant.jar” basedir=”${build.dir}”>
<manifest>
<attribute name=”Main-Class” value=”test.Main” />
</manifest>
</jar>
</target>
<target name=”主” depends=”compile, jar, docs”>
<description>Main target</description>
</target>
</project>

用ANT自動化:
Ant提供給Java開發人員有很大的幫助. 幾乎每一個Java開發人員會喜歡有一個腳本，可以運行單元測試和創建可在應用服務器上部署二進制分發文件的護理. 螞蟻還提供了一些方法來自動運行腳本這是用來在一個代碼庫進行單元測試. Thus, 它提供援助，以誰使用測試驅動開發方法的開發. As we know in test driven development methodology JUNIT is a compulsion, 它始終是一個額外的好處，如果我們有一個運行所有的JUnit測試用例一氣呵成自動化腳本. 不僅如此，如果我們有此腳本也可用於具有極好的裝備持續集成例如. 哈德森. Our following sample code illustrates how to use ANT with JUNIT.
LISTING 2: A Sample java file
[Code]
package com.home.junit;
公眾 類 SampleAdd {
公眾 詮釋 加(詮釋 x, 詮釋 y) {
return x + y;
}
}
[/Code]
LISTING 3: The corresponding JUNIT file
[Code]
package com.home.junit;
import org.junit.After;
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
public class SampleAddTest {
private SampleAdd sampleClass;
@Before
public void setUp() {
sampleClass = new SampleAdd();
}
@Test
public void testAdd() {
Assert.assertEquals(5, sampleClass.add(3, 2));
}
@After
public void settleDown() {
sampleClass = null;
}
}
[/Code]
LISTING 4: The ANT script to compile and run the JUNIT test
[Code]
<?xml version=”1.0″?>
<project name=”JUNIT” default=”主” basedir=”..”>
<!– Sets variables which can later be used. –>
<!– The value of a property is accessed via ${} –>
<property name=”src.dir” location=”src” />
<property name=”test.dir” location=”tests” />
<property name=”build.dir” location=”bin” />
<property name=”build.test.dir” location=”bin/tests” />
<!– Variables used for JUnit testin –>
<property name=”test.report.dir” location=”testreport” />
<!– Define the classpath which includes the junit.jar and the classes after compiling–>
<path id=”junit.class.path”>
<pathelement location=”lib/junit-4.11.jar” />
<pathelement location=”lib/hamcrest-core-1.3.jar” />
<pathelement location=”${build.dir}” />
</path>
<!– Deletes the existing build, docs and dist directory–>
<target name=”clean”>
<delete dir=”${build.dir}” />
<delete dir=”${test.report.dir}” />
</target>
<!– Creates the build, docs and dist directory–>
<target name=”makedir”>
<mkdir dir=”${build.dir}” />
<mkdir dir=”${build.test.dir}” />
<mkdir dir=”${test.report.dir}” />
</target>
<!– Compiles the java code (including the usage of library for JUnit –>
<target name=”compile” depends=”clean, makedir”>
<javac srcdir=”${src.dir}” destdir=”${build.dir}”>
<classpath refid=”junit.class.path” />
</javac>
<javac srcdir=”${test.dir}” destdir=”${build.test.dir}”>
<classpath refid=”junit.class.path” />
</javac>
</target>
<!– Run the JUnit Tests –>
<!– Output is XML, could also be plain–>
<target name=”junit” depends=”compile”>
<junit printsummary=”上” fork=”真” haltonfailure=”yes”>
<classpath refid=”junit.class.path” />
<classpath>
<pathelement location=”${build.test.dir}”/>
</classpath>
<formatter type=”xml” />
<batchtest todir=”${test.report.dir}”>
<fileset dir=”${test.dir}”>
<include name=”**/*Test*.java” />
</fileset>
</batchtest>
</junit>
</target>
<target name=”主” depends=”compile, junit”>
<description>Main target</description>
</target>
</project>
[/Code]
When we run this script, 它首先編譯代碼庫，然後運行在編譯代碼的JUnit測試，並最終生成測試報告. The test report can be generated in any format. For convenience we have generated this in XML format.

結論:
- Apache Ant的下列用途使用的Java開發一個基於Java的工具
- To generate the binaries from the source code
- To generate javadocs for the source code
- To run JUNIT test cases on a code base
- ANT in collaboration with JUNIT, helps the java developers to follow the Test Driven Development methodology
