Since you're using IntelliJ IDEA I suggest you let IDEA create your JAR file for you.

First, open up the module settings window:

<a href="https://i.stack.imgur.com/sr6t8.png" rel="noreferrer"><img src="https://i.stack.imgur.com/sr6t8.png" alt="enter image description here"></a>

Then, add a new artifact:

<a href="https://i.stack.imgur.com/3f5dQ.png" rel="noreferrer"><img src="https://i.stack.imgur.com/3f5dQ.png" alt="enter image description here"></a>

Select JAR From modules with dependencies:

<a href="https://i.stack.imgur.com/RTIVy.png" rel="noreferrer"><img src="https://i.stack.imgur.com/RTIVy.png" alt="enter image description here"></a>

Select your main class in the window and decide if you want to repackage all classes from your dependency JARs in your JAR (extract to target JAR option) or if you want to distribute them alongside your JAR (copy to the output directory and link via manifest option):

<a href="https://i.stack.imgur.com/rCAfr.png" rel="noreferrer"><img src="https://i.stack.imgur.com/rCAfr.png" alt="enter image description here"></a>

If you want to build it whenever you build the project (probably a good idea), click the checkbox for that:

<a href="https://i.stack.imgur.com/Gi9v5.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Gi9v5.png" alt="enter image description here"></a>

When you next Make the project, the JAR will show up under out/artifacts:

<a href="https://i.stack.imgur.com/60B4G.png" rel="noreferrer"><img src="https://i.stack.imgur.com/60B4G.png" alt="enter image description here"></a>

If you didn't click the checkbox for building the JAR when you build the project you can build the JAR from the Build Artifacts option in the Build menu.

Can you try using below command? Make sure to update 'classes' folder to the Base directory of the files to package.

As you said in question that you are able to run <code>danIDE.Main</code> so I assume all the required classes are available in dist folder.
So create a folder <code>out</code> in the project parallel to <code>dist</code>

<pre><code>javapackager -createjar -classpath [very-long-list-of-class-paths] -appclass danIDE.Main -srcdir dist -outdir out -outfile out.jar -v 
</code></pre>

Updated: as per the uploaded screenshot: point <code>-srcdir</code> to <code>dist</code>, now the generated jar <code>out.jar</code> will be placed in <code>out/out.jar</code>

I have created a <code>JavaFX</code> project and am able to run it with the command 

<code>java -classpath [very-long-list-of-class-paths] danIDE.Main</code>

However, when I try to use <code>javapackager</code> to create a jar out of it and run with <code>java -jar out.jar</code>, the prompt says <code>Error: Could not find or load main class danIDE.Main</code>

The command I used to create the jar is 

<code>javapackager -createjar -v -classpath [very-long-list-of-class-paths] -srcdir src -outfile out -appclass danIDE.Main</code>

I have googled for a long time on this problem and I still couldn't find the solution. Can someone point me to the right direction? Thanks a lot!

Edit: 
Here is the project structure. 

<a href="https://i.stack.imgur.com/3Lp9v.png" rel="noreferrer"><img src="https://i.stack.imgur.com/3Lp9v.png" alt="Project Structure"></a>

and here is the exploded jar.

New exploded jar as @Garry requested:
