1. Installing Groovy Plugin for Eclipse.
- Start Eclipse. Go to Help->Software Updates->Find and Install.
- Select "Search for new features to install" and click Next.
- Click on "New Remote Site"
- Give a name say "Groovy Plugin" and in the URL put "http://dist.codehaus.org/groovy/distributions/update/"
- Click Ok. Now select the newly added remote site and then click Finish. Follow the on-screen instructions and majorly you need to click "Install All" and then restart Eclipse for the changes to be effected.
2. Testing your Groovy installation on Eclipse.
- Create a new project in Java.
- Now in the Package Explorer right click on the project. You should see a "Groovy" item in the context menu.
- So go to the Groovy item in the context menu and go to "Groovy->Add Groovy Nature".
- Doing this would kind of convert our Java project to Groovy project. We can now run and test our Groovy programs.
- Now right click on the project and create a new package. Say "groovy.learning.samples".
- Then right click on the project and click on "New->Other". Type Groovy in the "type filter text" textbox. Now select "Groovy Class" and give it a name.(Tutorial1).
- Type the following line inside the code block already generated. Essentially you see a main already inserted.
"println("Welcome to Groovy World");
- Save the file. Now go to the menu "Run->Run As->Groovy Application". You should be able to see the message printed in the console. If so , you have successfully installed Groovy plugin on eclipse and good to write your Groovy programs.
This post, I hope, gives a quickstart to get started working with Groovy on Eclipse. In the subsequent posts, I hope to cover other basic programming constructs in Groovy.
