Groovy scripting is an integral part of the CPI. It is a perfect glue script in Java environments and it has integration history. There are a few annoyances to using it: The only way to check for syntax errors is to deploy the integration. The only way to check logic and functionality is to deploy the integration and ensure the message. Groovy Method Navigator. The Groovy Method Navigator tool parses the editor contents for Groovy methods or functions and displays them in a clickable list. Clicking an option from the list takes the user directly to the point in the editor where the method is defined. Groovy Method Selector. Eclipse Groovy Development Tools. This project provides Eclipse and Maven tooling support for the Apache Groovy programming language. Installation and usage information is available on the wiki.

Scott and others - any input on which IDEs or editors are best for Groovy and Grails? What do you use? I know IntelliJ has a plugin which I've jsut downloaded, and I'm pretty sure there's one for Eclipse. Any preferences?

I've used the IDEA plugin and while the groovy bits work well its been hit and miss with the grails plugin. I can't think of any specifics off the top of my head and it's been a few months since I've looked at it but I just remember having issues with many of the features like kicking off generator scripts and what not.

Thanks, Gregg.
A related question I'd add: for Java, we (here at JavaRanch at least) usually recommend that people first learn the basics without an IDE, because it hides too many details that you really should learn. Do Scott and others think that anything like that hold true for Groovy/Grails?

Forgive me for jumping in, but I also use IDEA with the JetGroovy plugin and it is working very well for both Groovy and Grails. Some of the generate scripts were not directly supported in earlier releases but they are in the latest. Even then it was easy to jump out to a shell and run those scripts.
The syntax highlighting, code completion (to an extent), refactoring and debugging are a huge productivity boost but the IDE does not really do anything for you that you would need to learn to do yourself. Much of what Java IDEs do in that regard is boilerplate code. And I agree that when you need to work with that stuff yourself and you're used to your IDE doing it you can get stuck. But with Groovy and Grails there is so much less boiler plate code so that issue all but goes away.
Just another POV,
Dave

I started playing around with Spring's Scripting support using Groovy tonight so I got to use the plugin quite a bit while creating my Groovy code. Just some notes:
When you try and use a class in a groovy file that needs to be imported you don't get the normal notification. You can still alt+enter on the class and then you get prompted for the correct action but auto import on alt+enter is no longer available.When creating a new groovy file if you choose script, even though you are in a package, the package statement is not generated for you. If you tell IDEA you want to create a Groovy class then all is well. This isn't good or bad. Just something to be aware of.Autocompletion is so-so. Yes, I am aware that Groovy is somewhat of a dynamic language however something as simple as accessor methods, IDEA should be aware those are automatically available and allow autocompletion for you. On the other hand it does autocomplete for message.message and since in Groovy that is the same as message.getMessage() I suppose its fine. But I still think IDEA should be smart enough to know that getMessage() is available.I can't find a way to tell IDEA to execute scripts as scripts. IDEA compiles them to bytecode prior to executing. Is this a big deal? Probably not and the code executes faster but seems unnecessary if I could turn it off.
That's all I came up with so far. If I find anything else I will post it here.

I created a class in a package and I needed to move it to a different package. I used IDEA's refactor and moved it to the new package however the package declaration in the groovy file didn't update to reflect its new home.

When implemeting an interface or extending an abstract class with abstract methods, IDEA doesn't warn you about required methods that need to be implemented. You can still alt+insert to see what needs to be done but until you compile/run your groovy code you won't know about it.Ranch Hand

How about a good plug-in for NetBeans or Eclipse. Mostly I'm looking for a worthwhile debugger.
I tried one a few months ago (Coyote, I think) and I could set a breakpoint in Java code that was executing a Groovy script and step into the Groovy code, but it didn't let me set a breakpoint in the Groovy code itself - which is very frustrating.
Any recommendations for either browser are welcome. Thanks!

Yeah, I'm also looking for a good plugin for NetBeans. I know there's one out there, but so far it only does some simple syntax checking and some other simple stuff without any Grails support. Hopefully the NetBeans team has already had a plan to build this plugin.

Neither NetBeans nor Eclipse are not there yet as far as the Groovy support is concerned. With all the buzz around Groovy and Grails, shouldn't be long before we see very good groovy support from these IDEs

I don't use netbeans at all until it becomes a little more flexible on project layouts.
Eclipse is my main IDE at work (we have Rational App Dev licenses, but it stinks). Groovy support in eclipse is poor. It is difficult to get the groovy plugin to pickup GSP files. There is no source formatting, completion is hit or miss but syntax highlighting does seem to work ok. I really miss the source formatting.
I have used Idea 7 with Groovy and Grails. As Dave Klein mentioned, JetGroovy is working pretty well in the current release. It's a little awkward to run the generate scripts in idea. Having a terminal handy is still really helpful.
I found TextMate (Mac-Only) to be one of the best interfaces to work with Ruby on Rails, and there are some textmate bundles for groovy. Groovy TextMate Bundle I imagine the grails support would work similar to RoR. TextMate's appeal, from what I can tell, is that it closely ties the file system and the editor. At least it feels a little more intuitive.
Disclaimer: my experience is based on a few weeks of trial use for Idea and TextMate. I still use a terminal with vi. If I did purchase an IDE, it would probably be Idea (I feel a little guilty for being a huge fan but not budgeting for this). Honestly, I put my fun money towards books and a good computer every few years, for now.

Groovy eclipse plug-in is not that great. When editing, I am all on my own. Is anybody aware of any vi/vim based utility for groovy/grails?

I've used all three. Eclipse is my main workhorse for normal Java development and is my favorite IDE. I have a license for IDEA and was excited to use it for Grails/Groovy development - but I find it to be sluggish.
However, I'd been playing around with Netbeans for a while as it's Javascript editor is awesome. Netbeans 6.5 includes better groovy/grails support and I've been using it for a couple of days. Earlier releases did not have a stable or usable groovy/grails plugin, but this latest version (I d/l nightly of NB6.5) shows great promise and is actually usable.
Another poster commented that 'you don't really need all them fancy features when working with Groovy' - I can't agree more. Once we get to a certain level of proficiency with Groovy, all you really need is a good editor and a shell.

I'm not sure what sluggish looks like. I'm running the Groovy/Grails plug in using IntelliJ 7.0.3 and it's anything but sluggish. The integration between Groovy, Java, Spring, and Hibernate is fantastic.

Deep insight into your code
IntelliJ IDEA analyzes your code, looking for connections between symbols across all project files and languages. Using this information it provides indepth coding assistance, quick navigation, clever error analysis, and, of course, refactorings.
Smart completion
Ctrl+Shift+Space gives you a list of the most relevant symbols applicable in the current context. This and other completions are constantly learning from you, moving the members of the most frequently used classes and packages to the top of the suggestions list, so you can select them faster.
Chain completion
Digs a tad deeper than Smart Completion and lists applicable symbols accessible via methods or getters in the current context. Say you're looking for a value of Project
and only have the Module module
declaration. Press Ctrl+Shift+Space twice to get module.getProject()
without any additional effort.
Static members completion
Lets you easily use static methods or constants. Offers a list of symbols matching your input and automatically adds required import statements.
Data flow analysis
When offering completion variants, IntelliJ IDEA analyses data flow to guess the possible runtime symbol type and refines choices based on that intel, automatically adding class casts.
Language injection
Brings coding assistance for a selected language to expressions and string literals in another one, complete with all advantages you would normally have. For example, you can inject fragments of SQL, XPath, HTML, CSS, or JavaScript code into Java String literals.
Cross-language refactorings
Knowing everything about usages of a symbol, IntelliJ IDEA offers extremely effective, thorough refactorings. For example, when you Rename a class within a JPA statement, it will update everything, from JPA entity class, to every JPA expression where it is used.

Detecting duplicates
Finds duplicate code fragments on the fly. Even if you're only about to extract a variable, constant, or a method, IntelliJ IDEA will let you know that there is a similar code fragment that can be replaced along with the one you're working on.
Inspections and quick-fixes
Whenever IntelliJ IDEA detects that you're about to make a mistake, a little lightbulb pops up in the editor. Clicking it or pressing Alt+Enter opens a list of actions you can take to make things right.
Developer ergonomics
Every aspect of IntelliJ IDEA is designed with ergonomics in mind. IntelliJ IDEA is built on a principle that every minute a developer spends in the flow is a good minute, and things that break developers out of that flow are bad and should be avoided.
Editor-centric environment
Most of your time the editor (and the code) is the only thing visible on your screen, and you don't need to leave it to do something that isn't coding-related.
Quick popups are helpful for checking additional information without leaving the context that you’re in. When you press Ctrl+Shift+I it shows you the definition for the symbol at caret.
To generate code, you don't have to walk through complex wizards or fill huge forms.
Shortcuts for everything
In IntelliJ IDEA you have dedicated keyboard shortcuts for nearly everything, including rapid selection and switching between tool windows and the editor.
Accessing a tool window via its shortcut moves the input focus to it, so you can use all keyboard commands in its context. When you need to go back to the editor, just hit Esc.
When you're in the Project tool window, you can not only navigate through the existing items, but also create new ones by just pressing Alt+Ins.
Best Groovy Editor For Eclipse

Ergonomic user interface
All lists, trees and popups in IntelliJ IDEA provide you with quick search that instantly takes you to a set of items that contain text you’re typing in them.
The first call of any IDE action is supposed to provide most expected results. Need more results? Press the shortcut again and the IDE will go deeper to find what you need.
Inline debugger
When you debug your code IntelliJ IDEA shows you variable values right in the source code, next to their usages.
You don’t even have to hover the mouse over the variable, or switch to the Variables pane of the Debug tool window.
Any time a variable changes its value, the IDE highlights it with a different color so that you can better understand how the state is changed over the code.
Built-in developer tools
To streamline your workflow, IntelliJ IDEA offers an unbeatable toolset right from the first start: decompiler, bytecode viewer, FTP and many more.
Version control
IntelliJ IDEA provides a unified interface for major version control systems including Git, SVN, Mercurial, CVS, Perforce, and TFS. The IDE lets you browse the history of changes, manage branches, merge conflicts and much more
Build tools
IntelliJ IDEA supports Maven, Gradle, Ant, Gant, SBT, NPM, Webpack, Grunt, Gulp and other build tools. Seamlessly integrated, these tools help automate compilation, packaging, running tests, deployment and other activities
Test runner and coverage
IntelliJ IDEA lets you perform unit testing with ease. The IDE includes test runners and coverage tools for major test frameworks, including JUnit, TestNG, Spock; Cucumber, ScalaTest, spec2, and Karma.
Decompiler
IntelliJ IDEA comes with a built-in decompiler for Java classes. When you want to take a look inside a library that you don't have the source code for, now you can – without any third-party plugins.
Terminal
Best Groovy Editor Free
The IDE comes with a built-in terminal. Depending on your platform, you can work with command line prompt, Far, powershell, or bash. Invoke the terminal with Alt+F12 and execute any command–without leaving the IDE.
Database tools
Take advantage of intelligent coding assistance when editing SQL; connect to live databases; run queries; browse and export data; and even manage your schemes in a visual interface–right from the IDE.
Application servers
IntelliJ IDEA supports major application servers: Tomcat, JBoss, WebSphere, WebLogic, Glassfish, and many others.
You can deploy your artifacts onto application servers and debug the deployed applications right from within the IDE.
Docker
Via a separate plugin, IntelliJ IDEA provides a dedicated tool window that lets you connect to locally running Docker machines to manage images, containers and Docker Compose services.
Polyglot experience
In addition to Java, IntelliJ IDEA offers first-class support for top JVM and non-JVM frameworks and languages out of the box.
First-class support for top frameworks
IntelliJ IDEA provides support for the most popular server-side and front-end frameworks.
Take advantage of extended coding assistance for Spring, Java EE, Grails, Play, Android, GWT, Vaadin, Thymeleaf, React, AngularJS and other frameworks.
Many languages–one IDE
