Hi,
Following the example at
http://maven.apache.org/guides/plugin/guide-ant-plugin-development.html
on how to write maven plugin using ant. I successfully created a hello
plugin. But now I'd like to add dependency management in my ant
build.xml by including maven-ant-tasks as a dependency in my pom:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>org.myproject.plugins</groupId>
<artifactId>hello-plugin</artifactId>
<packaging>maven-plugin</packaging>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>org.apache.maven</groupId>
<artifactId>maven-script-ant</artifactId>
<version>2.0.8</version>
</dependency>
<dependency>
<groupId>org.apache.maven</groupId>
<artifactId>maven-ant-tasks</artifactId>
<version>2.0.8</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<artifactId>maven-plugin-plugin</artifactId>
<dependencies>
<dependency>
<groupId>org.apache.maven</groupId>
<artifactId>maven-plugin-tools-ant</artifactId>
<version>2.0.8</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
</project>
The plugin builds fine. But when trying to run it, it's throwing a
ClassCastException. Is anyone using both maven-script-ant and
maven-ant-tasks together successfully? Here's the stacktrace:
java.lang.ClassCastException:
