Building visage fails with “No supported regular expression match”

Question

When building visage from source using ant-1.7 on ubuntu it fails with the message

build.xml:52: No supported regular expression matcher found: java.lang.ClassNotFoundException: org.apache.tools.ant.util.regexp.Jdk14RegexpRegexp

How do I solve this ?

Answer 1

The regular expression matcher is found in the ant-optional package for Ubuntu, and installing that solves the problem.

sudo apt-get install ant-optional

Answer 2

FYI in Centos the package name is ant-apache-regexp

yum install ant-apache-regexp

Answer 3

For suse 11 it is little bit longer

1.what is your ant exact version ? in my case it was 1.7.0

1. download the rpm : in my case the package name was ant-apache-regexp-1.7.0-200.2.noarch.rpm

2. execute the following

   rpm -i ant-apache-regexp-1.7.0-200.2.noarch.rpm
