Firstly, I installed the eclipse Groovy plugin, this was a piece of cake since I was only a few of steps away of it. Via the Marketplace of my Spring Tool Suite (STS): Help - Eclipse Marketplace - Search for Groovy -Install
![]() |
| Install Groovy plugin |
Groovy plugin for eclipse can be also found under the following URL: Groovy Plugin for Eclipse
Since, the first step was completed, I moved to the second one and I created a new Groovy class by following the path in Eclipse: File - New - Other - Groovy - Groovy Class.

| New Groovy class |
My java code was already under a Maven project, so I followed the standard maven approach and placed my Groovy classes under src/main/groovy and src/test/groovy and keep my Java classes under src/main/java and src/test/java structure.

| Maven Structure |
HINT: In case the Groovy folders /src/test/groovy and /scr/main/groovy are not displayed, select your project and by right clicking select Build Path - Configure Build Path - Add Folder then include the folders on your view as:
![]() |
| Display Groovy Folders |
Then, as a third step, I converted my project to a Groovy one by just selecting my project then by right clicking on option Configure - Convert to Groovy Project.

| Convert to Groovy |
In order to achieve it, in the pom.xml, I included the dependency tag for Groovy:
<dependencies>
<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-all</artifactId>
<version>${groovyVersion}</version>
<dependency>
</dependencies>
also, i needed a Groovy plugin with the goal “generateStubs”,so included the following tags:
<plugin>
<groupId>org.codehaus.gmaven</groupId>
<artifactId>gmaven-plugin</artifactId>
<configuration>
<providerSelection>1.8</providerSelection>
</configuration>
<executions>
<execution>
<goals>
<goal>generateStubs</goal>
<goal>compile</goal>
<goal>generateTestStubs</goal>
<goal>testCompile</goal>
</goals>
</execution>
</executions>
</plugin>
The goal "generateStubs" was I a surprise for me when I realized that, as its name dedicate,creates java stubs of groovy classes.To understand it, consider a java class which needs a Groovy one to compile with and since maven standard compile process starts with /main and /test java packages and then with the /main and /test Groovy packages, compilation would stop with errors without it.
