Sorry, I didn't noticed that you changed that. I do not see any
problem with sts.common project right now but yesterday it has
dependencies on local projects.

I'm not proposing to modify build.xml and buildaux.xml which are
currently could be regenerated... I'm proposing to create new very
simple one, let's say buildaux1.xml, which could looks like follows:

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse.ant.import?>

<project default="war" name="org.eclipse.higgins......buildaux1">
    <import file="buildaux.xml" optional="true"/>
    
    <target name="war">
        <antcall target="-copylibraries" >
            <param name="toDir" value="someTmpLocation"/>
        </antcall>
        <antcall target="-copyalljars" >
            <param name="toDir" value="someTmpLocation"/>
        </antcall>
        <war ... >
            ....
            <lib dir="someTmpLocation">
            </lib>
        </war>
    </target>

</project>

and regenerate build.xml.
