Step1. Setup Properties for Scalac Task

You may edit (or add to) the init.properties Ant target in order to set up the appropriate properties for the scalac Ant task.

<property name="scala-library.jar" value="${scala.home}/lib/scala-library.jar" />

<path id="build.classpath">
       <pathelement location="${scala-library.jar}" />
       <pathelement location="/Library/Frameworks/ERExtensions.framework/Resources/Java/ERExtensions.jar" />
<pathelement location="/Library/Frameworks/ERJars.framework/Resources/Java/log4j-1.2.14.jar" />
<pathelement location="/System/Library/Frameworks/JavaWebObjects.framework/Resources/Java/javawebobjects.jar" />
       <pathelement location="/System/Library/Frameworks/JavaEOAccess.framework/Resources/Java/javaeoaccess.jar" />
<pathelement location="/System/Library/Frameworks/JavaEOControl.framework/Resources/Java/javaeocontrol.jar" />
<pathelement location="/System/Library/Frameworks/JavaFoundation.framework/Resources/Java/javafoundation.jar" />
<pathelement location="/Library/Frameworks/ERAttachment.framework/Resources/Java/ERAttachment.jar" />


       <pathelement location="bin" />
<fileset dir="Libraries">
<include name="*.jar" />
</fileset>
<fileset dir="${wo.extensions}">
<include name="*.jar" />
</fileset>
</path>

<taskdef resource="scala/tools/ant/antlib.xml">
<classpath>
<pathelement location="${scala.home}/lib/scala-compiler.jar" />
<pathelement location="${scala-library.jar}" />
</classpath>
</taskdef>

Notes:

The first block of pathelements define the classpaths required by the scala compile to compile any .scala files in your project.

The taskdef sets up the Ant scalac task indicating the location of the

Step2. Edit the compile Target

Add the scalac task to the compile target, after the mkdir task:

<scalac srcdir="Sources" destdir="bin" classpathref="build.classpath">
<include name="**/*.scala" />
</scalac>
