How to setup IntelliJ IDEA for writing Java Kaa applications - intellij-idea

After following "Your first Kaa application" step-by-step guide at this link, I wished to develop a custom Java Kaa application using IntelliJ IDEA.
But, unfortunately, I couldn't find any way to setup my IDE in order to use its basic features (such as smart completion).
Can anyone suggest me a tutorial or a guide that could help me reaching my goal?
I really appreciate any help you can provide.

At the end, that's what I suggest to do after some research and some trials:
1) Create a new empty Java Project in IntelliJ IDEA
2) Generate and download Kaa Java Endpoint SDK archive file (follow Your first Kaa application guide for further informations)
3) Create a 'libs' folder in your Java project and move the .jar (something like kaa-java-ep-sdk-***.jar) in it
4) Create FirstKaaDemo.java file in 'src' folder and paste suggested Java application code in it.
5) Right-click on your project and Open Module Settings.
6) Add new JAR dependency and select your .jar file in 'libs' folder
This will solve every import error.
Hope this will help someone.

Create GWT project in Intellij IDE

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.

Can't load the main class/runnable jar JavafX 8 project [duplicate]

i created a Javafx project using JDK 8 and when i tried to export it to a runnable .jar file, i got surprised that it doesn't run using CMD, and gives the following error :
"Javafx compenents are missing"
while it works perfectly during the compiling time(using the IDE) when i accessed the .jar files, i found it has just .class files (that i made), and the needed library files that haven't been exported (i made sure to select the "extract need library files extract required libraries into generated jar" option in Eclipse), is there a reason behind of this? and a way to solve it? thanks in advance
Ps: i tried this using Eclipse and Intellij IDE
I just wanna mention once again that I'm using JDK 8 where it has JavaFX library inside of it.
Did you try this?
There are detailed instructions on how to configure your IDE to run JavaFX with newer OpenJDKs (which do not come with JFX components in it).
It also explains how to create a new JavaFX Maven project from archetype, with all the necessary plugins to easily build your application while including the minimal Java components for it (using jlink).
This will ensure that anybody using your application will have those components.

Intellij plugin development, SDK source file content

I can't figure out how to add the Intellij SDK plugin development source files to be able to navigate the files.
Right now I am only getting a decompiled list. I'd like the comments as well.
Note, I know there is https://github.com/JetBrains/intellij-community/blob/master/platform/platform-impl/src/com/intellij/openapi/editor/actions/
But shouldn't these already be included?
Can someone explain how to add the sources? I tried from module settings but couldn't get that to work.
If you're developing a plugin, or viewing/modifying an existing one, I suggest you take a look at the IntelliJ SDK docs, especially the prerequisites section, which explains how to set up a proper development environment.
Basically, you should clone IntelliJ community using
git clone git://git.jetbrains.org/idea/community.git idea
Then configure an IntelliJ SDK, and in the Sourcepath tab, add the local git repo to attach the source code.

How to properly import a Play 2+ project in IntelliJ 14+ with all integrated features (run, debug, test)?

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.

installing plugin in eclipse-cpp-helios-SR2-linux-gtk-x86_64

Can someone tell me how to install a map reduce (hadoop) plugin in eclipse-cpp-helios-SR2-linux ? Thanx in advance
hi
you can try this approach. Use any latest version of eclipse and than install CDT in it. This will allow you to write c/c++ application.
for your hadoop just go to you hadoop installation directory,here in contrib folder you will find eclipse plug-in in this folder you will get the jar file, just copy this file in to eclipse plug-in directory and restart the eclipse.
Now check for map-reduce perspective in window->open perspective and select build configuration according to your system
I don't know about the hadoop plug-in site if you find a site which provide hadoop plug-in than
There are two way to do it.
1:As you read over the net copy the plug-in and paste it into Eclipse plug-in folder and restart the eclipse. This is not the best way to install plug-in.
2: The proper way to install plug-in in eclipse is following :
Go to Help menu in Eclipse main window press Install new software.
Here in tab work with just put the address of website from where you want to install the plug-in.
Write any name for plug-in than look in the text box. it will provide you proper name of the plug-in and "next " tab at the bottom will be activated.
Press the next tab,It will install your plug-in .
At the end of installation just restart the eclipse to take the new setting effect.
