After much googling and attempting to find out how to make this work, I'm emailing for help :)
The ant optional task "replaceregexp" replaces the contents of a file by using a regular expression. Because there are multiple regexp libraries, ant loads the regexp class selected by a property after the replaceregexp class is loaded. See http://ant.apache.org/manual/OptionalTasks/replaceregexp.html for info on the task or for more info on the regexp mapping, see: http://ant.apache.org/manual/CoreTypes/regexp.html#implementation So the simplest build.xml would look like this: <project name="testrun"> <property name="ant.regexp.regexpimpl" value="org.apache.tools.ant.util.regexp.Jdk14RegexpRegexp" /> <target name="dochange"> <echo>Classpath ${compileClasspath}</echo> <taskdef name="replaceregexp" classname="org.apache.tools.ant.taskdefs.optional.ReplaceRegExp"> <classpath path="${compileClasspath}"/> </taskdef> <replaceregexp file='${basedir}/test.h' match='define VERSION' replace='define TEST' /> </target> </project> with test.h having the contents simply "define VERSION" and running out-of-the-box binary distribution ant 1.6.5, this works fine. Doing this in maven, though, has issues: maven's filter doesn't do regular expressions, so I decided to call the build.xml using antrun. Note the commented-out dependencies from when I tried all of the different regexp implementations! Running out-of-the-box maven 2.0.4 I get the following error. The class in question (org.apache.tools.ant.util.regexp.Jdk14RegexpRegexp) is actually INSIDE the same .jar file that contains the replaceregexp (org.apache.tools.ant.taskdefs.optional.ReplaceRegExp) : ant-nodeps.jar Any suggestions? From googling, I've seen that the maven 1.1 way to deal with this was to make the dependencies use "classloader root" but that's not valid syntax in maven 2! Thanks for any help or suggestions!
