Groovy + ANT

ANT, ,

Using groovy script in ANT to read XML file, update build.properties with XML content and call another ANT task to for each repeating XML node.

XML file content:

<?xml version = “1.0” encoding = “UTF-8”?>
<BuildConfig CI_BuildConfig.xsd”>
<BuildName>NightlyBuild</BuildName>
<Target_ENV>INTEGRATION</Target_ENV>
<TagArtifacts>false</TagArtifacts>
<Applications>
<ApplicationConfig>
<Name>name1</Name>
<SVN_Path>path1</SVN_Path>
</ApplicationConfig>
<ApplicationConfig>
<Name>name2</Name>
<SVN_Path>path2</SVN_Path>
</ApplicationConfig>
<ApplicationConfig>
<Name>name3</Name>
<SVN_Path>path3</SVN_Path>
</ApplicationConfig>
</Applications>
</BuildConfig>

ANT Build.xml contents:

 

<path id=”groovy.classpath”>

</path>
<taskdef name=”groovy” classname=”org.codehaus.groovy.ant.Groovy” classpathref=”groovy.classpath”/>
