Note that you need to escape a dollar-sign ($) with
another dollar-sign in Ant.
The regexp mapper needs a supporting library and an implementation
of org.apache.tools.ant.util.regexp.RegexpMatcher that
-hides the specifics of the library. Ant comes with implementations for
-the java.util.regex package,
-jakarta-regexp and jakarta-ORO. If you compile
-from sources and plan to use one of them, make sure the libraries are
-in your CLASSPATH. For information about using Since Ant 1.8.0 Ant
+ requires Java 1.4 to run, so the implementation based on
+ the java.util.regex package will always be available.
+ You can still use Jakarta ORO or Jakarta Regex instead if your
+ provide the corresponding jar in your CLASSPATH.
For information about using gnu.regexp or gnu.rex with Ant, see this article.
-If you want to use one of the supported regular expression
- libraries you need to also use
- the corresponding ant-[jakarta-oro, jakarta-regexp, apache-oro, apache-regexp}.jar
+
+
If you want to use one of the regular expression
+ libraries other than java.util.regex you need to also use
+ the corresponding ant-[apache-oro, apache-regexp].jar
from the Ant release you are using.
Make sure, both will be loaded from the same
classpath, that is either put them into your CLASSPATH,
ANT_HOME/lib directory or a nested
<classpath> element of the mapper - you cannot have
-ant-[jakarta-oro, jakarta-regexp, apache-oro, apache-regexp].jar in ANT_HOME/lib
+ant-[apache-oro, apache-regexp].jar in ANT_HOME/lib
and the library
in a nested <classpath>.
Ant will choose the regular-expression library based on the
