I'm beginner in using IntelliJ IDEA IDE and I want to create a new GWT project. I have added the GWT plugin to IntelliJ IDEA and now and I want to create a project. I googled but I didn't find a helpful tutorials or examples. Did you have guys a helpful tutorials to start. Thanks in advance.
Do not use the GWT project builders from IntelliJ or Eclipse. Both generate projects which use the same class path for client and server. In todays GWT development it is common to use a separate class path for client and server.
Depending on the server you prefer to use, choose:
https://github.com/tbroyer/gwt-maven-archetypes
in case you want to use Jetty or Tomcat on the server side or:
https://github.com/NaluKit/gwt-maven-springboot-archetype
in case you want to use Spring Boot.
How to create a new GWT project in IntelliJ
Create a new project: File → New... → Project...
Select Java EE (Legacy).
Select Java 8.
Do not use Java 9 or above unless you know what you're doing. Yes, GWT 2.8.2+ works with Java 11+, but you'll need to open some internal modules for it to work. If you just want to learn GWT, stay with Java 8.
In Additional Libraries and Frameworks, check ☑ Google Web Toolkit.
In GWT SDK, fill in the path to your GWT installation.
Check ☑ Create sample application and introduce a fully qualified class name for the main class.
Click Next, and fill in the rest of needed info for your new project (this has nothing to do with GWT).
You'll end up with something like this:
If you followed the steps closely, the sample project should be fully functional. IntelliJ should've created a Run configuration for you, too, so you can run the GWT app right away and see it in action:
This is all explained in the official help documentation for IntelliJ 2020.1, which was the last version to include GWT support out of the box.

I work on a Java based Play! project for severals months now and I'd like to import it completely in IntelliJ, meaning being able to run, compile, test and debug from IntelliJ, without the need to use the command line.
According to this post from Jetbrain, it seems to be possible, if I quote the article it says clearly : "Now you don’t need to switch between IntelliJ IDEA and Play console anymore. Everything is available right from your favorite IDE.", but I can't figure out a way to achieve this for now, even if I follow the tutorial provided by Jetbrains.
Here are the steps I've been throught :
Open my fav IDE IntelliJ ;)
Go to the project list window.
Import project
Import from external model and choose SBT as suggested in Jetbrains tutorial.
option "Use auto import" checked, option "create directories for empty content roots automatically" checked. Project SDK Java 1.7
Global sbt settings : JVM From project JDK.
Finish
By now, if I try to make the project and launch it from IntelliJ, I'll get scala compiling errors related to routes object. Thanks to this post, we can understand that this happens because scala routes are located to specific folders that needs to be included in IntelliJ sources settings for this project. So next step was :
File -> Project Structure -> Modules
Add target/scala-2.10/classes:target/scala-2.10/resources_managed:target/scala-2.10/src_managed as sources folders.
But my problem remains the same, routes object being unrecognized.
Notes : I have no scala facets in my project structure configuration nor can add one.
IntelliJ provides integrated support for the Play Framework for Scala and Java. Support is currently only available in IntelliJ Ultimate Edition (see the Frameworks and Technology section).
Assuming Ultimate Edition, the setup for Play is incredibly easy. Simply create a new project by importing build.sbt, then choose Add Framework Support and choose Play 2.
Once complete, you can start and stop Play using the Play 2 Run/Debug configuration. No command line necessary.
Here is a more in depth look at IntelliJ's Play project configuration.
You could try the command play idea if you are using play or activator idea if you are using activator. That will do the magic.
On the page https://www.jetbrains.com/idea/whatsnew/ it is said that Intellij Idea 14 has got a visual diagrams for spring integration.
But I can't find how to visualize my integration xml file.
(right click on file)/Diagrams/Show Diagram... shows a diagram with links between the beans. It is not very usefull.
Spring Integration Patterns plugin is enabled
I have Intellij Idea installed on a computer without access to the internet. May it be the reason why the diagrams are not working properly?
What do you want to see there?
For example.
We have stomp-chat sample: https://github.com/spring-projects/spring-integration-samples/tree/master/applications/stomp-chat
And here is a diagram for this config: https://github.com/spring-projects/spring-integration-samples/blob/master/applications/stomp-chat/src/main/resources/org/springframework/integration/samples/chat/stomp/server/stomp-server.xml
I'd say that it is OK, however I agree that it would better if I'd provide id attribute for all components.
Of course, Spring Integration Patterns plugin has to be switched on.

"Please make sure the XML file is correctly configured in Spring context setup via Spring facet.
It requires spring-integration-core to be in module dependency of selected XML file."
I had the same problem, and found that in addition to having the Spring facet enabled, and having the spring-integration-core dependency and having the relevant context file set as an application context under the facet, you also need to have just the containing module open. i.e. the stomp-chat spring-integration sample provides the "Spring Integration" diagram option if it is opened from its own pom.xml, however if you open the parent applications\pom.xml then the "Spring Integration" diagram option is not available, regardless of facets etc.
I have the same problem in a project where I use spring integration 2.1.4.
In a newer project I use 4.0.0 and there Intellij Idea offers the option to open the spring integration diagram.
Perhaps that is the reason and you "only" need a newer version of spring integration.
The issue is that the newer versions of Intellij create separate modules per source set by default which somehow ends up conflicting with earlier setups. Using Intellij 2016.1, I instead reimported my project with the following options checked:
Once I did that then (right click on file)/Diagrams/Show Diagram once again gave me the Spring Integration Option.
Yes, click on your Spring Integration context file > Diagrams > Show Diagram... > Spring Integration., but if you haven't this menu follow below:
You should have identified integration context as Spring XML based configurations. Instruction here : Create a Intellij file set
I don't know why, but I had a problem with Spring Integration Diagram when I installed Springirun plugin.
I'm just starting to develop a new eclipse plugin where I want a web application server running in Eclipse. I found a nice blog, OSGi as a Web Application Server, that describes how to do this. The author suggests creating a target environment for my bundle requirements, and some of those bundles get pulled in from the Equinox Project SDK (now called Equinox Target Components in Juno). I notice that the tutorial project runs fine when my target platform is the platform I created in the tutorial, but fails to start when it is the default platform. So, now for my question...
If I need bundles that are not part of the default, how will my plugin project get access to those bundles? Will I need to deploy them along with my plugin? How would I know if the user's eclipse does or does not already have those required bundles?
You was not much clear about what kind of application you are developing. Running a web server in an Eclipse IDE as a plugin don't make any sense to me. This kind of server application is best just running on top of Equinox.
Anyway, the right path is to create a "Product Configuration" file and add categories that contains the needed bundles (go to File/Plug-in Development/Product Configuration).
With this file you can run an instance of the product (inside the IDE) and can export it (create a zip containing all needed bundles)
And if you want to able your user to install plugin inside his IDE you must create a P2 repository (using a Target Definition File) and expose the exported directory within a Http server. You could research about Tycho to build this kind of components in a maven style.
Well, I'm not sure if re-inventing the wheel again is really sufficient.
You might take a look at Pax-Web for inspiration on how to do it, or take a look Apache Karaf as a OSGi-Container (using Pax-Web). Or even better start contributing to one of the two :-)
I am a beginner with Play2 framework and Scala.
Is there any eclipse play 2 plugin available?
If yes, then please provide me the link for the same. I am used to Eclipse and have never used Scala before;hence in a confusion like how and where to start from. Looking at the Play2 Doc, sems like working in command prompt IDE which is very difficult (though I have tried yet)
Please let me know the eclipse plugin for Play2 or some other IDE helpful for this.
Regards,
There in no plugin as such for Eclipse.
Play! framework has nice set of tools for doing tasks such as following
creating new play project
running the project
deployment of the application
doing the continuous testing mode etc
Trust me, once you start using this, you gonna love it.
Beside you do not require any experience in Scala, as for Play framework you can use Java language, if you are comfortable with it (you can choose Java template while creating new Play project )
and also you can use IDE for syntax highlighting , code completion etc
I had a brief try of Play development using Eclipse and the Scala Plugin. I personally found it awkward and not terribly helpful. (The errors which the IDE reported were not always the same as the ones that the Play compiler reported, for example.)
I’ve had a lot more joy using the Intellij IDEA IDE, with its Scala plugin. As with Eclipse the current version of IDEA does not have specific support for Play Framework 2, but it does have specific support for Scala.
The next version of Intellij IDEA, v12, will have explicit support for Play Framework 2: http://www.jetbrains.com/idea/nextversion/index.html#Frameworks_Support (but only in the paid-for ‘Ultimate’ edition, not in the free ‘Community’ edition).
IDEA has many plugins to use. I.e. IDEtalk is one of them which I use. How can I code a simple plugin that just connects to Internet and shows a web page? (no need for an address bar but it is not a problem to be). I want my plugin's shortcut's button locate at my IDE as like IDEtalk, Commander, Maven Projects etc.
Any ideas?
Check the documentation and the source code of the other plug-ins available in the public git repository of the Community Edition.
There is a Creating Your First Plugin guide on JetBrains web site. It covers all the needed steps from plugin creation to deployment to the plugin repository.
You might also want take a look in the source code of a simple plugin like Twitter Integration Plugin which I recently implemented. Or check a more complex one like this one.
