Groovy ShortTypeHandling ClassNotFoundException

ShortTypeHandling was introduced in groovy-all-2.3.0.jar so the quick fix was to replace the older groovy-all-x.x.x.jar with groovy-all-2.3.0.jar. This solved the runtime ShorTypeHandling ClassNotFoundException but also created new problems by introducing a new groovy-all.jar dependency in the application.

The real issue was how the groovy compiler was being invoked via maven. Because I introduced spock which required groovy 2.0, I needed to update the maven entries for the groovy-eclipse-compiler dependency. Here are the updated maven entries for working with groovy 2.x:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
            <configuration>
                <compilerId>groovy-eclipse-compiler</compilerId>
                <!-- Java version -->
                <source>1.7</source>
                <target>1.7</target>
            </configuration>
            <dependencies>
                <dependency>
                    <groupId>org.codehaus.groovy</groupId>
                    <artifactId>groovy-eclipse-compiler</artifactId>
                    <version>2.8.0-01</version>
                </dependency>
                <dependency>
                    <groupId>org.codehaus.groovy</groupId>
                    <artifactId>groovy-eclipse-batch</artifactId>
                    <!-- Groovy version -->
                    <version>2.1.8-01</version>
                </dependency>
            </dependencies>
        </plugin>

With this in place, I could leave my groovy-all dependency the way I originally had it for the working/fully tested application like this:

    <dependency>
        <groupId>org.codehaus.groovy</groupId>
        <artifactId>groovy-all</artifactId>
        <!-- If possible, its better if this matches 2.1.8 in the plugin definition -->
        <!-- but 2.2.1 worked fine here and allowed me to keep the original pom definition  -->
        <version>2.2.1</version>
    </dependency>

The application runtime no longer references the ShortTypeHandling class and everything worked as it previously did.
