"ant clean start build-ext" creates the D:/Java/tomcat-5.5.17 directory, and several sub directories.
This directory should not be created since we are just building the EXT environment.
This happens because the jar target calls the deploy target:
<target name="jar" depends="compile">
<ant dir="../portal-service" target="deploy" inheritAll="false" />
<ant dir="../util-bridges" target="jar" inheritAll="false" />
<ant dir="../util-java" target="jar" inheritAll="false" />
<ant dir="../util-taglib" target="deploy" inheritAll="false" />
It should call "jar" instead
