Create JAR file using Net Beans including all dependent libs and folders

I have created a JavaFX application using NetBeans IDE and below is my folder structure.
I want to a build a single jar file including all dependencies for this jar to work properly.
This jar requires testplanner and batch folder from project root directory and files inside dist folder to work properly.
How can I package all this to a single jar file?

Theoretically JAR files cannot contain dependencies within, as java does not support it out of the box. WAR and EAR archives can. What You want to do is not standard, but is named fat jar. Fat jars are used i.e. by spring-boot maven plugin, but you could try this:

And some more explanation:
NetBeans - deploying all in one jar

Use tecreations Deploy. Put all your sources into a path declared as Tecreations.getProjectPath(), run BuildAll to create your corresponding classes, put your jars in projectpath/jars and select the appropriate settings, whether to include jars, sources or classes. Select your main class and click Deploy. Unsigned and signed output jars are produced in user/Documents.

Java export jar including libraries

I have been looking around for some time now, but didn't a find way how to export a JAR (not runnable jar) that contains in it's build path the referenced libraries.
Using Eclipse, I have included the lib folder which contains the jars of the referenced libraries in the export process.
Importing that JAR to another project and calling some method results in a ClassNotFoundException.
Looking at the MANIFEST, I didn't see any reference to those jars in the classpath, though the jars are indeed included in the jar.
So my questions are:
1. Is there any way to accomplish the packaging of the non-executable JAR so it will include libraries?
2. Is there any best practice for building and deploying a jar that include other jars libraries?

I tried it too but it doesn't work for me. I added the final .jar file but it doesn't work.
So, I did a workaround.
Extract the .jar file that you want as a dependency.
Copy that content and put it all inside your .jar file.
Add your .jar file as dependency inside an eclipse project.
Run it and see if everything is ok.

Getting class from ear/war in ear/lib/jar returns ClassNotFoundException

My project structure is the following. Server is Glassfish 4. IDE - netbeans 7.4. Project temp is used by project a.
EAR
+ lib/temp.jar
+ a.war
Temp.jar contains core classes. They are used by war. Temp.jar doesn't import any files from war, and it must know about war nothing. But, temp.jar has classes that creates instances of war classes by reflection (according to xml file). Here I get ClassNotFoundException. How can it be fixed? Is it possible to fix or I have wrong project structure?
Note: I didn't put temp.jar in a.war as there can be different war files that can use this jar.

I found the answer.
If we put jar into ear/lib folder then the classes in it can be accessed but they can't access the classes out of lib (in this case there is no need to add something to manifest file of war).
If we put jar in root of ear or in any other folder ear/bum than the classes of these jar can access war classes.
So I conclude, that /lib is monodirectional, any other are bidirectional.
Hope it will save someone a lot of time.

Add jar file to the you lib folder.
Change MANIFEST.MF and add the particular jar path to Bundle-ClassPath.
That worked for me.

JSPF is not loading lib of jar

I am using Java Simple Plugin Framework. I export a jar that has my plugin implementation. The implementation depends on a library, which I have as a jar. That jar gets exported within the lib directory of my jar, and added to the classpath of my jar.
But when I load my jar with JSPF, it fails with "NoClassDefFound" because it can't find the jar in the lib director of my jar.
My apologies if my approach off base; I just need to know how this is supposed to be done. How should I bundle my plugin implementation as a jar if it depends on another jar?

I used JSPF and achieved this requirement the following way:
place the library jar file in a folder called lib outside the plugin jar file. (So that
the lib folder and the plugin jar file is in the same folder). Then I added lib/"name_of_libjar" to the classpath entry in the manifest.mf file of the plugin jar file (Which should be inside the plugin jar files META-INF folder), and it worked fine for me.

How to add jars available in a particular folder to classpath at runtime only for specific wars:

I am using maven build tool.
The following two are my intentions.
1) To move some of the third party library jars out of my war from WEB-INF/lib folder [note: These jars are common between more than 2 war files (or artifacts)]
2) To make the war file small in size.
Is it possible to move those jars out of war and put it into a folder and these jars should be referred in the classpath only by the wars which require it.
I have tried adding the path to the jars in the Class-Path: of MANIFEST.MF of war files but it did not work out. Please help me out.

I assume the jars in question are necessary for compiling the code that make up the web application. If the third-party jars are necessary for compilation but you don't want them in your war file, you have two options:
In the <dependency></dependency> section for the third-party jar, add "<scope>provided</scope>".
Configure the maven war plugin to exclude the jars you don't want in the war. See http://maven.apache.org/plugins/maven-war-plugin/examples/skinny-wars.html for the details.
How you get the jar files that you exclude from the war into the web container's classpath depends on your environment. If you are using ear files, the Maven docs above talk about how to get the jars included in the ear file. If you are not using ear files, you will have to come up with your own way to get the jars into the container's lib directory.
