ant finds no supported regular expression matcher

Bug #172789 reported by Thomas Ravkilde on 2007-11-29
Affects Status Importance Assigned to Milestone
ant (Ubuntu)

Bug Description

Binary package hint: ant

I have a <filterchain> that looks like

                <tailfilter lines="-1" skip="1" />
                    <replaceregex pattern="(characterSet name=.Extended Latin .ANSEL..+?>)"

which fails build with the output
"No supported regular expression matcher found: java.lang.ClassNotFoundException:"
using the ant 1.7.0-3 ubuntu package

However, downloading ant 1.7.0 from and doing a manual install in ~/lib works like a charm. Perhaps an issue with the default classpath?

I am using java-1.5.0-sun installed with Synaptic.

Best Regards,

Though this is closed, what solved it for me in centos / fedora was:

yum install ant-apache-regexp

hope that helps someone, for me it was just beneficial doing yum search ant | grep -i optional

and since none of the repos i have (rpmfusion for instance) have a ant-optional package: you can pick and choose what you actually need for your project.

for me, the current list I get (11/04/2012)
