Execute my groovy script with ant or maven

Question

I have the following:

• 1 java class
• 1 bat file (starts the groovy script)
• 1 groovy file

All in the same folder.

Now I want to use Maven or Ant to run the groovy file but I can't get it to work. Is there someone who can show me how to write this pom.xml or build.xml? I don't want to use the bat file anymore.

Answer 1

With Maven, use the gmaven plugin. From its documentation:

Execute a Local Groovy Script

<plugin>
    <groupId>org.codehaus.gmaven</groupId>
    <artifactId>gmaven-plugin</artifactId>
    <version>1.3</version>
    <executions>
        <execution>
            <phase>generate-resources</phase>
            <goals>
                <goal>execute</goal>
            </goals>
            <configuration>
                <source>${pom.basedir}/src/main/script/myscript.groovy</source>
            </configuration>
        </execution>
    </executions>
</plugin>

And trigger the specified phase.

Or, if you don't want to bind the plugin to a particular phase, you could configure it like this:

<plugin>
    <groupId>org.codehaus.gmaven</groupId>
    <artifactId>gmaven-plugin</artifactId>
    <version>1.3</version>
    <configuration>
        <source>
           println "Hi"
        </source>
    </configuration>
</plugin>

And call

mvn groovy:execute

Answer 2

There is a groovy plugin for ANT that can invoke groovy scripts

<groovy src="helloWorld.groovy"/>

I would recommend combining it with ivy which can download the required jars for you, similar to the Maven example given previously.

build.xml

<project name="demo" default="run" xmlns:ivy="antlib:org.apache.ivy.ant">

    <target name="resolve">
        <ivy:resolve/>
        <ivy:cachepath pathid="build.path"/>
    </target>

    <target name="run" depends="resolve">
        <taskdef name="groovy" classname="org.codehaus.groovy.ant.Groovy" classpathref="build.path"/>

        <groovy src="helloWorld.groovy"/>
    </target>

</project>

ivy.xml

<ivy-module version="2.0">
    <info organisation="org.myorg" module="demo"/>
    <dependencies>
        <dependency org="org.codehaus.groovy" name="groovy-all" rev="1.7.4" conf="default"/>
    </dependencies>
</ivy-module>
