Setting up VS Code for GUI development using JavaFX.

[@harshith_takkala]

Some problems to which these are solutions. 1. "Error: Could not find or load main class app Caused by: java.lang.ClassNotFoundException: app" Solution: When u click the run button , VS code gives a warning, "The file app.java isn't on the classpath, the runtime may throw class not found error. Do you want to add the parent folder "APP/JavaFx Application/src" to Java source path?" Click yes. This warning is show only if you have installed "Debugger for Java" extension. If this warning is not shown by your VS code, then you can paste the below code in your settings.json, where you find the location of your jar files that you import. ``` "java.project.sourcePaths": [ "JavaFx Application/src" ] ``` If you have any other projects to add under this project, you can update this list accordingly. 2. After this you might me seeing one more error. "Error: JavaFX runtime components are missing, and are required to run this application" Solution: Fist, Debug your application's code. Can be done by "create a launch.json file" under "RUNAND DEBUG" of Explorer section. Add this vmArgs to the configuration which has the projectName in it. ``` "vmArgs": "--module-path D:\\Java_JFX\\javafx-sdk-14.0.2.1\\lib --add-modules javafx.controls,javafx.fxml", ``` It should be the path to the JavaFX lib folder. Then it will work. 👌✨ like anything !!

Thank You for your hard work! It took me so much time to get it up and running but this helped a lot in the end.

Welcome ✌ Watch another video on the same topic, which makes easy to compile and run !!!

If I open a Java Fx project that was created by someone else using a Clips, I don’t see the reference library in my visual studio code. How can I add them?

[@harshith_takkala]

As we have chosen "No build tools" here, this step of creating directory structure has been automated in newer versions of VSCode. This video has been outdated. It detects if the imported folder is java project or not. Then we can manually add jar files in the lib folder. Hope you got it.

Thank you, good and thorough video 👍

Any recommendation on how to generate JavaFX getters and setters?

Sorry no idea about that

Hey, I am getting the error: Error: JavaFX runtime components are missing, and are required to run this application How do I fix this?

May be you havent imported the required dependency jar files or may be your command for compile is wrongly typed. Checkout my other video on the same

Do I have to copypaste the compile an run code lines anytime i want to run my code?

[@harshith_takkala]

No that's not. This is an idea to compile and run javafx along with importing jar files for auto complete. You can check the next video with the same topic which is modified and efficient. This can help you to run code in a click.

@@harshith_takkala hey, thanks for responding, I'm currently watching that video but i'm still having the "Error: Could not find or load main class App Caused by: java.lang.ClassNotFoundException: App". I already edited settings.json to: "java.project.sourcePaths": [ "JavaFx Application/src" ] but it still throw that error

[@harshith_takkala]

@@waldosobrino4589 have you imported the jar files required?.

[@harshith_takkala]

@@waldosobrino4589 yes. I think you might have put the vmArgs in the object inside configuration list with the mainClass as "${file}". You must include the vmArgs in the configuration with the mainClass declared as "App" (the name of project's main class. Hope you get it

[@rexis2684]

thanks alot for the help .

[@jerrydaniel9660]

Hello, please I did not get that part of using command line to change the directory can you be more specific on how it is done. Thanks.

[@harshith_takkala]

Are you asking for the moment at 5:10 Yes, it automatically opens. But now VS code has updated. It has provided many features for java developers. This automatic opening of new VS Code window from the project root directory will be done after clicking the confirmation button at the bottom of window after you do these steps.

[@jihadkhawaja]

For anyone having the Class exception or file not found error, just navigate to the project App . java location in the terminal using cd then run the commands.

[@harshith_takkala]

Yeah 🙂

[@justylove7935]

Why I haven't line Java:Create java Project ?? can you explain pls ??

[@harshith_takkala]

May be you haven't installed the extensions I guess .

[@justylove7935]

@@harshith_takkala sr my english not good :< But I think I had java extensions pack

[@harshith_takkala]

@@justylove7935 no problem. ✌ May be 1. Restart the whole procedure. 2. Search the "create java project" in command palette, (not in the search box, that may also opens sometimes) (command palette search starts with ">", while search doesnt start with ">". 3. After installing all, it will ask for reload, tou have to reload vs code. If these doesnt work, then I also dont know the slexaxt solution and dont know what's the exact problem you have. Hope you got it 🙂

Ok, explain in brief

[@rockstylex33]

I can't believe all this mickey mouse is required, how did software development evolve to this type of huge pile of crap just to get to a point so you can start? This might be a good video, but the IT world needs to get away from installations that are a huge tangled mess like this.

[@harshith_takkala]

Yeah the point is absolutely correct, but we have evolved a lot. We were using machines with floppy/drives to install any software. And then internet has evolved and installations were easier. Open source evolved and installations were free. Linux distros came into picture and made most of the installations complete with a single command !!! And also we have IDEs to make our development easy right?. This was just an experimental video of how you can make a semi text editor, work and provide functionality like IDE....
