ant build script issue

I have 2 ant build scripts named "build" and "tarne"

Build:

<?xml version="1.0" ?>
<project name="build" default="zip">

    <property name="project.name" value="projectName"/>
    <property name="version" value="default_version_value"/>


    <taskdef resource="net/sf/antcontrib/antcontrib.properties">
        <classpath>
            <pathelement location="lib/build/ant-contrib.jar"/>
        </classpath>
    </taskdef>  

    <var name="version2" value="default_version_value"/>


    <property name="tmp" value="tmp"/>  
    <property name="build.dir" location="${tmp}/component/${project.name}"/>
    <property name="java.classes" location="${tmp}/component/${project.name}/classes"/>
    <property name="weblayout.dir" location="${tmp}/weblayout/resources/${project.name}"/>


    <path id="compile.classpath">
        <fileset dir="lib" includes="**/*.jar" />
        <fileset dir="lib/build" includes="*.zip" />
    </path>

    <target name="clean">
        <delete dir="${tmp}" />
    </target>

    <target name="init" depends="clean">
        <mkdir dir="${java.classes}" />
    </target>

    <target name="compile" depends="init">
        <javac srcdir="src" source="1.5" target="1.5" encoding="utf-8" includes="开发者_C百科**/*.java" destdir="${java.classes}" classpathref="compile.classpath" />
    </target>

    <target name="copy-resources" depends="compile">

            //Lots of copying here

    </target>

    <target name="read.version" description="Parses the hda file for your version number">

        <property file="${project.name}.hda" prefix="hda"/>
        <propertyregex property="version" input="${hda.version}" regexp="\." replace="-" global="true" override="true"/>
        <var name="version2" value="${version}"/>

        <echo>${version}</echo>
        <echo>${version2}</echo>


    </target>

    <target name="zip" depends="copy-resources, read.version" description="Package component">

        <zip destfile="${project.name}-${version}.zip" basedir="${tmp}" />
        <delete dir="${tmp}" />

    </target>


</project>

Tarne:

<?xml version="1.0" ?>
<project default="tarne">

    <include file="build.xml"/>
    <property name="project.name" value="build.project.name"/>

    <target name="tarne">

        <antcall target="build.read.version" inheritRefs="true"></antcall>
        <property name="version" value="build.version"/>
        <property name="version2" value="build.version2"/>

        <echo>${version}</echo> 
        <echo>${version2}</echo>    



    </target>

</project>

And the output I get when I run tarne.xml is:

Buildfile: tarne.xml
tarne:
build.read.version:
     [echo] v1-0-1
     [echo] v1-0-1
     [echo] default_version_value
     [echo] default_version_value

Where the first 2 lines (v1-0-1) are from inside the read.version target of build.xml and the next 2 lines are from tarne.xml. The general idea is that I should be able to access the version number in my tarne.xml build script.

Any ideas on what's going wrong?

Antcall does not support what you intend to do:

http://ant.apache.org/manual/Tasks/antcall.html : The called target(s) are run in a new project; be aware that this means properties, references, etc. set by called targets will not persist back to the calling project.

you could try:

  <target name="tarne" depends="build.read.version">
  </target>

which would keep the new values.

Try

<property name="version" value="${build.version}"/>         
 <property name="version2" value="${build.version2}"/>
