Re: How to create a fat jar for my JavaFX program?

[Davide Perini]

Done it here.

https://github.com/sblantipodi/JavaFastScreenCapture/blob/JavaFXJavaModule/pom.xml

If you read my sources there is how to configure the maven pom.
You need then create a simple class with a main that doesn't extends 
application that simply call the main in the class that extends application.


Hope it helped

Once you have a JRE image that includes JavaFX, then your application
Jar files (all of them, no need to make anything 'fat') can easily be
bundled with that JRE using jpackage.

I have done Gradle scripts to do all that and it wasn’t difficult.

Re: How to create a fat jar for my JavaFX program?

[Ty Young]

Don't know anything about fat jars, but you could try this jlink plugin:


https://tentackle.org/static-content/sitedocs/tentackle/latest/tentackle-jlink-maven-plugin/jlink-mojo.html


It works with non-modular projects as well - everything just gets dumped 
into a folder and put onto the module path. Just follow the standard 
Maven jlink guide:



https://maven.apache.org/plugins/maven-jlink-plugin/usage.html


but use the above plugin instead. I've been using it and it works great.


Hope this helps.

GraalVM native-image does not work directly with JavaFX. You would have to
use the Gluon client-maven-plugin 

to get that going but I would not recommend that as a first try because 
it is just too difficult.

You can try that step later.

In order to create a real platform installer with jpackage and

module system at all. Have a look at this tutorial which I co-autored

no it is not. There are seveal ways how to bundle native libraries.
jpackage is one way, fat jars are another. And for fat jars of course
you can extract native libraries at runtime (JNA does exactly that).
What is difficult is the handling of native dependencies. If you know
what you are doing you can manually load native libraries in the right
order.

The alternative is to distribute a ZIP file and setup the paths prior
to loading libraries. Changing the java.library.path takes some
reflection, but it is possible to do at runtime.

The javafx jars from maven central hold the native libraries.

no it is not. There are seveal ways how to bundle native libraries.
jpackage is one way, fat jars are another. And for fat jars of course
you can extract native libraries at runtime (JNA does exactly that).
What is difficult is the handling of native dependencies. If you know
what you are doing you can manually load native libraries in the right
order.

The alternative is to distribute a ZIP file and setup the paths prior
to loading libraries. Changing the java.library.path takes some
reflection, but it is possible to do at runtime.

The javafx jars from maven central hold the native libraries.

Unfortunantly so few dependencies supports Java Modules this day, so fat 
JAR is the only way I can do it.


Thanks

A fat jar isn’t a good way to distribute a Java application these days. Now you 
should probably be using jpackage and/or jlink to bundle your application 
classes with a runtime suitable for running the application.

Hi all,
thanks for the great project, I love JavaFX.

I always used the maven plugin to crete fat jars with all my deps. The 
resulting jar is an executable one and ready to use.

This is my pom that create the fat jar.

but when I try to exceute the jar I get this error:

Error: JavaFX runtime components are missing, and are required to run this appli

if I explode the fat jar I can see that there are the javafx class in it. what 
am I doing wrong?

Thanks

The JavaFX classes are there, but what about the native libraries?

How to create a fat jar for my JavaFX program?

Hi all,
thanks for the great project, I love JavaFX.

I always used the maven plugin to crete fat jars with all my deps. The 
resulting jar is an executable one and ready to use.


This is my pom that create the fat jar.

but when I try to exceute the jar I get this error:

Error: JavaFX runtime components are missing, and are required to run 
this appli

cation


if I explode the fat jar I can see that there are the javafx class in 
it. what am I doing wrong?


Thanks
