> Classloader issue with ant optional tasks in a hierarchical structure
> ---------------------------------------------------------------------
>
> Key: MANTRUN-61
> URL: http://jira.codehaus.org/browse/MANTRUN-61
> Project: Maven 2.x Antrun Plugin
> Issue Type: Bug
> Affects Versions: 1.1
> Environment: Windows XP Pro
> Reporter: Zarar Siddiqi
>
> I have a classloading issue with ant optional tasks which I've imported via
> ant-nodeps-1.6.5.jar.
> I have a multi-module maven project with three levels of heirarchy.
> 1
> a
> i
> ii
> b
> i
> ii
> 2
> ...
> ...
>
> I'm using the maven-antrun-plugin in module 1.a.i in the following manner.
> <plugin>
> <artifactId>maven-antrun-plugin</artifactId>
> <executions>
> <execution>
> <id>execution1</id>
> <phase>generate-sources</phase>
> <configuration>
> <tasks>
> <replaceregexp flags="g"
>
> file="${file}"
>
> match="${match}"
>
> replace="${replace}"/>
> </tasks>
> </configuration>
> <goals>
> <goal>run</goal>
> </goals>
> </execution>
> </executions>
> <dependencies>
> <dependency>
> <groupId>ant</groupId>
> <artifactId>ant-nodeps</artifactId>
> <version>${ant-nodeps.ver}</version>
>
> </dependency>
> <dependency>
> <groupId>jakarta-regexp</groupId>
> <artifactId>jakarta-regexp</artifactId>
> <version>${jakarta-regexp.ver}</version>
> </dependency>
> <dependency>
> <groupId>ant</groupId>
> <artifactId>ant-jakarta-regexp</artifactId>
> <version>${ant-jakarta-regexp.ver}</version>
> </dependency>
> </dependencies>
> </plugin>
> If I cd to the the 1.a.i directory, and execute mvn generate-sources, all is
> fine. But if I execute the same command from either 1 or 1.a, I get the
> following error:
> Embedded error: Could not create task or type of type: replaceregexp.
> Ant could not find the task or a class this task relies upon.
> This is common and has a number of causes; the usual
> solutions are to read the manual pages then download and
> install needed JAR files, or fix the build file:
> - You have misspelt 'replaceregexp'.
> ...blah blah blah
>
>
> Now this is because it can't find the classes in the ant-nodeps,
> jakarta-regexp and ant-jakarta-regexp jars even though they are explicitly
> declared in the dependencies for the plugin.
> I messed around with the <classloader>root</classloader> variable by
> specifying it in the pom but that didn't go anywhere. I've also tried to
> declare the dependencies as part of the pom rather than the plugin but with
> no success.
> I'm following the instructions here (Using optional ant tasks).
