How to get the calling target in a script?

[Sebastien Diot]

Most of our build.xml looks like this:

        <target name="CalcExt" depends="edlohn-enhanced,eurodata,PayrollExt">
                <antcall target="buildSubDir">
                        <param name="subDir" value="CalcExt"/>
                        <param name="classpath" 
value="${build}/edlohn-enhanced.jar:${build}/eurodata.jar:${build}/Payro  
llExt.jar"/>
                </antcall>
        </target>

We antcall buildSubDir with the calling target name, and its dependencies 
turned into a classpath.

What I would like is to simply say:

        <target name="CalcExt" 
depends="edlohn-enhanced,eurodata,PayrollExt,buildDir"/>

With buildDir defined as a script, so that it fetches the calling target 
name and dependencies, and uses that to call buildSubDir like in the first 
example:

        <target name="buildDir">
                <script language="javascript"> <![CDATA[
                        callingTaget = "CalcExt";
                        projectname = lohn;
                        dep = 
projectname.getTargets().get(callingTaget).getDependencies();
                        buildDir = ":" + projectname.getProperty("build") + "/";
                        cp = "";
                        while(dep.hasMoreElements()) {
                                cp = cp + buildDir + dep.nextElement() + ".jar";
                        }
                        strbuf = new java.lang.StringBuffer(cp);
                        if (strbuf.length() > 0) {
                                strbuf.deleteCharAt(0);
                        }
                        projectname.setProperty("buildDir.classpath", 
strbuf.toString());
                        projectname.setProperty("buildDir.dir", callingTaget);
                ]]></script>
                <antcall target="buildSubDir">
                        <param name="subDir" value="${buildDir.dir}"/>
                        <param name="classpath" value="${buildDir.classpath}"/>
                </antcall>
        </target>

So, what can I do to get the name of the calling target, so that I can set 
it in the variable callingTaget ?
