Wayne, I am able to resolve this issue but got some other issue. I guess this issue is due to differnent class loaders. See the following pom file. When I was putting junit dependency at pom level which is now commented out, I was having issue but now what I did I added this dependency for plugin and it was able to find junit task in ant file.
All looks fine till here but when I tried to do mvn install from main project, I got the same issue. This pom file is for sub probject which builds successfully but from main project, I still get the old problem. The other subprojects have their dependencies to junit. Any idea how I could load all my dependencies all together via one class loader. If it is not a class loader issue, what it could be, any pointers would be really really appreciated. Here is my working pom file for sub project . <project xmlns="http://maven.apache.org/POM/4.0.0"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd";> <modelVersion>4.0.0</modelVersion> <parent> <groupId>com.comp.cp</groupId> <artifactId>cp-component</artifactId> <version>1.0-SNAPSHOT</version> </parent> <groupId>com.comp.cp</groupId> <artifactId>ClientTests</artifactId> <version>1.0-SNAPSHOT</version> <packaging>pom</packaging> <name>ClientTests</name> <!-- <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.3.1</version> </dependency> </dependencies> --> <build> <finalName>clienttests</finalName> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.0</version> <configuration> <source>1.5</source> <target>1.5</target> </configuration> </plugin> <plugin> <artifactId>maven-antrun-plugin</artifactId> <executions> <execution> <id>1</id> <phase>generate-sources</phase> <configuration> <tasks> <ant antfile="build.xml" /> </tasks> </configuration> <goals> <goal>run</goal> </goals> </execution> </executions> <dependencies> <dependency> <groupId>ant</groupId> <artifactId>ant-junit</artifactId> <version>1.6.5</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.3.1</version> </dependency> </dependencies> </plugin> </plugins> </build> </project> Wayne Fay <[EMAIL PROTECTED]> wrote: I'm curious... why you can't just use Maven Surefire plugin to run your JUnit tests?
