[mojo-user] How do I compile for groovy runtime 1.0 using groovy-maven-plugin?

[Eric Lessard]

I am using the Maven 2 Groovy plug-in to build a jar file that can be used
with a Groovy 1.0 runtime. If I use the plug-in without any kind of special
configuration and I try to use the generated jar file with a 1.0 runtime, I
get the following exception:

java.lang.NoClassDefFoundError: org/codehaus/groovy/runtime/GStringImpl

How can I work around this problem?

Here's what my pom file look like:

<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>

        </dependency>
    </dependencies>

                <artifactId>groovy-maven-plugin</artifactId>
                <extensions>true</extensions>
            </plugin>
        </plugins>
    </build>
</project>

Any help would be appreciated.

Thanks,
