How to export Maven project to exe (or jar) file using Eclipse?

Question

I have done a Maven project and I would like to export it into a runnable exe (or jar file).

After I exported it into runnable .jar file, the file wouldn't open.

What I did -> Right click on project -> Refresh -> Export -> Runnable Jar File -> Package Required ...

Same thing for .exe file, I used launch4j and exported to an .exe file and it wouldn't run either.

What I did -> Right click on project -> Refresh -> Export -> Runnable Jar File -> Extract Required ... JRE min: 1.11.0 (I'm using openjdk-11.0.2)

Does anybody have any tips on this? Thank you!

What I did:

clean compile assembly:single -> Jar file with dependencies created

clean package -> exe file created

Problem: The exe file opens and closes immediately. How do I fix this? Is this because of my source code error?

Updated pt.2:

Error: A JNI error has occurred, please check your installation and try again

Update Pt3: I have changed minJre to 1.11.0 Error: JavaFX runtime components are missing, and are required to run this application

Although, I have openjdk 11.0.2 installed.

openjdk version "11.0.2" 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)

I also have javafx sdk 11.0.2 external jres file in my user library

My VM arguments

--module-path "C:\Program Files\Java\javafx-sdk-11.0.2\lib" --add-modules javafx.controls,javafx.fxml```

Right click on project -> Run As -> Maven build It will ask the Goals : clean package

You will find the jar in target

If Maven build is intended for something else, use Run configurations and create a new Run with the goals above

(all this, taken as granted it is a maven project, otherwise, you might want to mavenize it before, including the launch4j configuration in order to generate the exe file)

Hey Inquirymind, I have tried your way and found my exe jar file in target folder, but it still does not run – WhyMyCodeLong Jan 14 '20 at 21:15
What does it say when you try to run? The size is similar to the one generated by eclipse? – inquirymind Jan 14 '20 at 21:33
It does not say or pop-up anything at all. The size is significantly less than the one generated by Eclipse – WhyMyCodeLong Jan 14 '20 at 21:51
You might share the pom with us, so we can try to guess what's going on – inquirymind Jan 14 '20 at 21:53
No reference to launch4j in the pom. Here an example https://stackoverflow.com/questions/37295726/create-exe-with-launch4j-with-maven – inquirymind Jan 14 '20 at 22:01
Hi, I will try it and let you know soon! Thanks – WhyMyCodeLong Jan 14 '20 at 22:03
Hi I have updated the post, please take a look. Thanks! – WhyMyCodeLong Jan 15 '20 at 15:53

Are you executing on command line? Please share the output with us – inquirymind Jan 15 '20 at 20:59
I have updated the error. It looks like the compiler is outdated .. – WhyMyCodeLong Jan 16 '20 at 21:10
You are running with Java8 after having compiled with java 11. Try changing the minor version of jre in launch4j configuration 1.8 -> 1.11 – inquirymind Jan 17 '20 at 19:29
I changed and got a new error ```Error: JavaFX runtime components are missing, and are required to run this application```. I have openjdk 11.0.2 installed – WhyMyCodeLong Jan 20 '20 at 17:23
Have to tried this? https://stackoverflow.com/a/52603536/12493323 – inquirymind Jan 20 '20 at 18:48
Hey, the problem is if I try to compile with goal clean compile javafx:run. It will work perfectly. I have installed jre as javafx jdk 11.0.2 with added external jres (javafx.etc). Again, once I run it with goal clean package, it will generate .exe file but open and close immediately. Run in cmd and the error javafx run time .. above still there. – WhyMyCodeLong Jan 20 '20 at 19:08
It evolved into a problem beyond maven and exe generation. It is about Java 11 modules. You might want to create a new post specialized (java-11 and java-modules tags) – inquirymind Jan 21 '20 at 10:35
