Автоматизиране на изграждане с Ant
Преглед:
В този документ, ние ще говорим за мравката натрупването инструмент и използването на този, как можем да се автоматизира механизма за изграждане на Java базирани приложения. В днешната епоха мравка се превърна в неразделна част от развитието на Java. Повечето клиенти искали да имат автоматизирана изграждане скрипт като част от доставената изходния код. Причината за това е простотата, предоставена от мравката, така че всеки с малко скриптове знания може да генерира разгръщат двоичен, без да знаят за прилагането в детайли.
Въвеждане:
Apache ant is a generic build tool. трибуните името ANT съкратените за "Друг Neat Tool". Този инструмент е подобен на помощната програма "Make" в UNIX, но се осъществява чрез използване на Java. Той се използва предимно за изграждане на изпълними файлове на Java базирани изходния код и разгръщане на генерирания двоичен до сървър за приложения, който е предварително зададен. 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. По подразбиране името на този файл е build.xml. Някои предприемачи също се използва свойства подават именно build.properties да се определят някои свойства например. the build version number and other environmental parameters which are required to change from time to time based on the need.
Installation:
ФЕДОРА: 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=”основен” 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=”основен” depends=”compile, jar, docs”>
<description>Main target</description>
</target>
</project>

Автоматизация използване ANT:
Ant осигурява голяма полза за Java разработчици. Почти всеки Java разработчик ще искал да има скрипт, който може да се грижи за тичане теста за единица и създаване на двоичен файл за разпределение, които могат да бъдат разположени на сървър на приложения. Ant също така предоставя начини за показване автоматизирани скриптове, които се използват за извършване на единица тестове на база код. Thus, тя предоставя помощ на разработчиците, които използват подхода за развитие на тест задвижване. As we know in test driven development methodology JUNIT is a compulsion, тя винаги е едно допълнително предимство, ако имаме автоматизиран скрипт, който работи на всички случаи на изпитване JUnit с един замах. Не само, че този сценарий може да се използва, ако имаме има непрекъсната интеграция заглажда например. Hudson. Our following sample code illustrates how to use ANT with JUNIT.
LISTING 2: A Sample java file
[Code]
package com.home.junit;
публичен клас SampleAdd {
публичен Int добави(Int x, Int 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=”основен” 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}” />

When we run this script, тя първо съставяне на база код и след това минава тестове JUnit на компилиран код и накрая генерира доклад за изпитване. The test report can be generated in any format. For convenience we have generated this in XML format.
