[Bug 172789] Re: ant finds no supported regular expression matcher

[matthew day]

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)

[root at work cave]# yum search ant | grep Optional
ant-antlr.i686 : Optional antlr tasks for ant
ant-apache-bcel.i686 : Optional apache bcel tasks for ant
ant-apache-bsf.i686 : Optional apache bsf tasks for ant
ant-apache-log4j.i686 : Optional apache log4j tasks for ant

Title:
  ant finds no supported regular expression matcher

Status in “ant” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: ant

  I have a <filterchain> that looks like

              <filterchain>
                  <tailfilter lines="-1" skip="1" />
                  <tokenfilter>
                      <filetokenizer/>
                      <replaceregex pattern="(characterSet name=.Extended Latin .ANSEL..+?>)"
                                    flags="s"
                                    replace="\1<code><marc>95</marc><ucs>95</ucs></code><code><marc>96</marc><ucs>96</ucs>&lt$
                  </tokenfilter>
              </filterchain>

  which fails build with the output 
  "No supported regular expression matcher found: java.lang.ClassNotFoundException: org.apache.tools.ant.util.regexp.Jdk14RegexpRegexp"
  using the ant 1.7.0-3 ubuntu package 

  However, downloading ant 1.7.0 from http://ant.apache.org/ 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,
  Thomas
