As mentioned in the comments, the <a href="https://openjfx.io/openjfx-docs/#introduction" rel="noreferrer">Starting Guide</a> is the place to start with Java 11 and JavaFX 11.

The key to work as you did before Java 11 is to understand that:

<ul>
<li>JavaFX 11 is not part of the JDK anymore</li>
<li>You can get it in different flavors, either as an SDK or as
regular dependencies (maven/gradle).</li>
<li>You will need to include it to the module path of your project, even if your project is not modular.</li>
</ul>

JavaFX project

If you create a regular JavaFX default project in IntelliJ (without Maven or Gradle) I'd suggest you download the SDK from <a href="https://gluonhq.com/products/javafx/" rel="noreferrer">here</a>. Note that there are jmods as well, but for a non modular project the SDK is preferred.

These are the easy steps to run the default project:

<ol>
<li>Create a JavaFX project</li>
<li>Set JDK 11 (point to your local Java 11 version)</li>
<li>Add the JavaFX 11 SDK as a library. The URL could be something like <code>/Users/&lt;user&gt;/Downloads/javafx-sdk-11/lib/</code>. Once you do this you will notice that the JavaFX classes are now recognized in the editor.</li>
</ol>

<a href="https://i.stack.imgur.com/TF5zy.png" rel="noreferrer"><img src="https://i.stack.imgur.com/TF5zy.png" alt="JavaFX 11 Project"></a>

<ol start="4">
<li>Before you run the default project, you just need to add these to the VM options: 

<code>--module-path /Users/&lt;user&gt;/Downloads/javafx-sdk-11/lib --add-modules=javafx.controls,javafx.fxml</code></li>
<li>Run</li>
</ol>

Maven

If you use Maven to build your project, follow these steps:

<ol>
<li>Create a Maven project with JavaFX archetype</li>
<li>Set JDK 11 (point to your local Java 11 version)</li>
<li>Add the JavaFX 11 dependencies. 

<pre><code>&lt;dependencies&gt;
 &lt;dependency&gt;
 &lt;groupId&gt;org.openjfx&lt;/groupId&gt;
 &lt;artifactId&gt;javafx-controls&lt;/artifactId&gt;
 &lt;version&gt;11&lt;/version&gt;
 &lt;/dependency&gt;
 &lt;dependency&gt;
 &lt;groupId&gt;org.openjfx&lt;/groupId&gt;
 &lt;artifactId&gt;javafx-fxml&lt;/artifactId&gt;
 &lt;version&gt;11&lt;/version&gt;
 &lt;/dependency&gt;
&lt;/dependencies&gt;
</code></pre></li>
</ol>

Once you do this you will notice that the JavaFX classes are now recognized in the editor.

<a href="https://i.stack.imgur.com/pHXzF.png" rel="noreferrer"><img src="https://i.stack.imgur.com/pHXzF.png" alt="JavaFX 11 Maven project"></a>

You will notice that Maven manages the required dependencies for you: it will add javafx.base and javafx.graphics for javafx.controls, but most important, it will add the required classifier based on your platform. In my case, Mac.

This is why your jars <code>org.openjfx:javafx-controls:11</code> are empty, because there are three possible classifiers (windows, linux and mac platforms), that contain all the classes and the native implementation.

In case you still want to go to your .m2 repo and take the dependencies from there manually, make sure you pick the right one (for instance <code>.m2/repository/org/openjfx/javafx-controls/11/javafx-controls-11-mac.jar</code>)

<ol start="4">
<li>Replace default maven plugins with those from <a href="https://github.com/openjfx/samples/blob/master/IDE/IntelliJ/Non-Modular/Maven/hellofx/pom.xml" rel="noreferrer">here</a>.</li>
<li>Run <code>mvn compile javafx:run</code>, and it should work.</li>
</ol>

Similar works as well for Gradle projects, as explained in detail <a href="https://openjfx.io/openjfx-docs/#gradle" rel="noreferrer">here</a>.

EDIT

The mentioned Getting Started guide contains updated <a href="https://openjfx.io/openjfx-docs/#IDE-Intellij" rel="noreferrer">documentation</a> and sample projects for IntelliJ:

<ul>
<li>JavaFX 11 without Maven/Gradle, see <a href="https://github.com/openjfx/samples/tree/master/IDE/IntelliJ/Non-Modular/Java" rel="noreferrer">non-modular sample</a> or <a href="https://github.com/openjfx/samples/tree/master/IDE/IntelliJ/Modular/Java" rel="noreferrer">modular sample</a> projects.</li>
<li>JavaFX 11 with Maven, see <a href="https://github.com/openjfx/samples/tree/master/IDE/IntelliJ/Non-Modular/Maven" rel="noreferrer">non-modular sample</a> or <a href="https://github.com/openjfx/samples/tree/master/IDE/IntelliJ/Modular/Maven" rel="noreferrer">modular sample</a> projects.</li>
<li>JavaFX 11 with Gradle, see <a href="https://github.com/openjfx/samples/tree/master/IDE/IntelliJ/Non-Modular/Gradle" rel="noreferrer">non-modular sample</a> or <a href="https://github.com/openjfx/samples/tree/master/IDE/IntelliJ/Modular/Gradle" rel="noreferrer">modular sample</a> projects.</li>
</ul>

The issue that JavaFX is no longer part of JDK 11. 
The following solution works using IntelliJ (haven't tried it with NetBeans):

<ol>
<li>Add JavaFX Global Library as a dependency:

Settings -> Project Structure -> Module. In module go to the
Dependencies tab, and click the add "+" sign -> Library -> Java->
choose JavaFX from the list and click Add Selected, then Apply settings. </li>
<li>Right click source file (src) in your JavaFX project, and create a new
module-info.java file. Inside the file write the following code :

<pre><code>module YourProjectName { 
 requires javafx.fxml;
 requires javafx.controls;
 requires javafx.graphics;
 opens sample;
}
</code></pre>

These 2 steps will solve all your issues with JavaFX, I assure you.</li>
</ol>

Reference : There's a You Tube tutorial made by The Learn Programming channel, will explain all the details above in just 5 minutes. I also recommend watching it to solve your problem:

It is 2021 and JetBrains updated their IDE. The other questions about this error message are closed and point here.
<pre><code>Error: JavaFX runtime components are missing, and are required to run this application

If you have followed all of the other steps in these answers (eg. Libraries, <code>--module-path</code>, <code>--add-modules</code>, version matching JDK and JavaFX), and you still see this compile error, make sure your run/compile configuration has <code>--module-path</code> and <code>--add-modules</code> as <code>VM Options</code> and not <code>Program Arguments</code> in IntelliJ.

I'm having trouble getting IntellJ to recognize JavaFX packages. With a new JavaFX project, with OpenJDK 11, when trying to build the project, IntelliJ can't recognize the JavaFX packages.

I've imported <code>openjfx:javafx-base-11</code> from the Maven repo.

I've looked at other questions and the solutions seem to range from checking that the bytecode is at the right level (mine is), and that the project language is correct (mine is).

Anyone have any ideas?

我在让IntellJ识别JavaFX包时遇到了问题。对于新的JavaFX项目和OpenJDK 11，当尝试构建该项目时，IntelliJ无法识别JavaFX包。我已经从Maven导入了openjfx:javafx-base-11。我已经研究过其他问题，解决方案似乎包括检查字节码是否处于正确的级别(我的是)，以及项目语言...
