Run and Debug Java in WSL 2 with Intellij IDEA on Windows 10

Intellij IDEA is installed on Windows. The java application built with maven requires native libraries (with JNI) and runs on Ubuntu.
Using maven and git on Windows is fine. How can I point Intellij IDEA to use the JDK from WSL so I can create a run/debug configuration that uses the WSL?

Deploy your app on WSL with Power Shell, and remote debug

Install Intellij IDEA with version >= 2021.1.
Configure WSL. To work with WSL 2, your Windows version should be 10 build 18917 or later. Make sure you add the needed JDK version in WSL. In order to use Maven, You also need to add a path variable export M2_HOME=/path/to/maven to the .profile file.
Create, open and develop the project in corresponding WSL environment.
Select the project SDK as the JDK configured in WSL.
Ensure that firewalls allow connections using WSL.

Installing java,tomcat ,eclipse and maven in ubuntu

I am new to java and to get my project working I need eclipse, java, tomcat and maven. I am using Ubuntu. Is there any particular order for installations? Is there any place I can get a detailed read about it?

To install JDK (Java Development Kit): http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
To install JRE (Java Runtime Environment): http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html
To install Eclipse: https://www.eclipse.org/downloads/
To install Tomcat: https://tomcat.apache.org/download-90.cgi
You need to install JRE first because Eclipse is built with Java. Select the appropriate pacgakes to the Ubuntu OS in the download pages.
Maven is included in the Eclipse EE environment.

Installing FX Experience Tools

I am building a desktop application using JavaFX, and have installed scene builder integrated with NetBeans. Now I am trying to install fx experience tool on my windows platform but getting some JRE problem.
All my NetBeans and Scene Builder with JDK 8 environment working fine only error with installing FX Experience Tool.
** Log File Link **

Since you didn't specify the name of the tool, I initially assumed you were referring to ScenicView.
But you are using fxetools, I was able to install and run it on Java 1.7.0_71 under Windows 8.1.
Here's what you do:
In the directory that contains fxetools, there is a jre directory that is included (1.6.0_30).
RENAME this directory from jre to jre6.
NOW, when you start fxetools, it should look to your currently installed jre, or at least, to the jre specified by JAVA_HOME. I don't know whether the application is fully functional, but at least it should run for you now as it did for me. See http://i.stack.imgur.com/HO7n8.jpg

Installing Eclipse/Java on Ubuntu

I'd like to install Eclipse on Ubuntu for Java development. I'm happy to trade having the newest version for steady updates via package management.
I've done the usual sudo apt-get install eclipse eclipse-jdt (java-7-openjdk-i386 is installed and working)
However, when I start Eclipse, there seems to be almost nothing available - no Java editing (not even 'Installed JREs' is present under Window/Preferences). I've tried adding various update sites, installing Marketplace client, WTP, Java EE etc. but just can't get a working install. Oddly, I have it running fine on another machine I set up about a year ago (with the help of How do I install Eclipse Marketplace in Eclipse Classic?)
I've given up and reverted to a manual install (along the lines of Eclipse 3.6 Helios for Ubuntu 10.10) but wanted to ask:
Am I missing something obvious?

I strongly recommend you not to install Eclipse in that way, it is not really useful and you will get just the Eclipse with the Java Standard Perspective. What I recommend you is to download the tar.gz file from the page (including the Java EE perspective). Copy the tar file in a directory where you want all your development tools, like /home/user/dev/eclipse and start from there. You can create a launcher in your desktop to get a faster access to the IDE. When I started with Ubuntu, I used to install the way you had installed (sudo apt-get...) but I can tell you that the best way to do is to install it manually. If the JDK is well installed, you will not have any problem launching your Eclipse. Best regards.

Groovy and grails jdk issue

I wish I could give you guys more information on what's going on, but I really have no idea. I am trying to install groovy and grails tools suite from springsource and I am having trouble configuring it to work properly. I have the most up to date JDK, and the preferences show it, but I still get warnings and it does not build. I have posted some pictures below to show what is going on.

on your GGTS go to window
select java
select installed JREs
add-> Standard VM
jRE home select directory up to C:\Program Files\Java\jdk1.6.0_18
select jdk1.6.0_18 from installed JREs

I faced a similar issue (I am sure it is the exact issue) - Here are the steps to ensure it works correctly, I struggled with initially but this got it going.
Install JDK from http://www.java.com ,in a directory where there are NO SPACES in the path
Set JAVA_HOME to your JDK installation
Ensure %JAVA_HOME%\bin; is in your PATH variable.
On the command prompt run java -version, it should give you the path where JDK is installed
Install STS Springsource Tool suite.
Run your STS and create a new grails project and run it.
Let me know if that does not work.

It might be that you are launching Eclipse with a JRE even though you have a JDK installed as one of the compilers in your workspace. To find out if you are launching with a JRE or JDK, go to Help -> About GGTS -> Installation details -> Configuration
Look for the -vm option and make sure it is a JDK not a JRE.
