| Mappers and Closure can 't be nullable | Mappers and Closure can 't be nullable 2005-05-03 - By Casey Daniell
What am I overlooking here, I remember getting this working before, but its
been a while. Can anyone think of something I am overlooking here? I am
basically trying to strip out the version string from the jar file's name.
<fileset id="lib-files" dir="${libs.dir}">
<include name="gateway-2.3.6.jar"/>
</fileset>
<copy todir="${deploy.dest}/lib">
<fileset refid="lib-files"/>
<mapper type="regexp"
from="^(\w+(\-*\w*)*)(\-+([0-9]?.?)*)*(.jar)$$"
to="\1\5"/>
</copy>
I then get the following error when running ANT:
Y:\LATEST_CODE\RCFileExchange\build.xml:174:
org.apache.regexp.RESyntaxException
: Syntax error: Closure operand can't be nullable
