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 ?
The regular expression matcher is found in the
ant-optional
package forUbuntu
, and installing that solves the problem.sudo apt-get install ant-optional
