I have created a project in netbeans and I clean and built the jar file. But I double clicked on jar file doesn't run the jar file.
Why is this jar file is not running ?

you didn't give us very much information, but if you are developing in windows, and your program is all console based, when you double click the jar, it will run, but you will not be able to see it because it has nothing to show you the output in. You can get around this two different ways.
1. Develop your own console gui
2. run the jar through cmd. you can write a batch file to do this for you if you want.

How can I convert my Java program to an .exe file?

So i just finished a small Java program that I've been working on throughout the week and I want to generate an .exe file of it so I can share with my friends. I'm working on Apache Netbeans 11.3 and JDK 8.
I can successfully generate the .jar file but that's pretty much useless.
If you created a java project, then the "other" computer should have the java runtime installed, in order for the jar to be executed there (java -jar your.jar) otherwise if you really want an .exe use one of the many jar2exe converters found on the almighty internet, such as ja2exe you can download it

I have a spring based workflow system where the java plugins are uploaded and kept in jar format, they are referred and used by the jar file. However, I have seen that jar file is very easy to decompile and it is a security risk.
I tried obfuscation as well. I want to run exe so that it is run at byte code so it is very very hard to reverse engineer.
You could use ProGuard as optimizer and obfuscator.
ProGuard also has a maven plugin that you can use it in the build process.

While run in NetBeans it runs perfectly but when build and go to dist and run executable jar file report cannot run. Then I tried to run in cmd I got an error

It looks like the version of ASM library is different when program runs inside NetBeans and when run in cmd. Review your project setup and ensure that your IDE setup matches your standalone setup.

If you Export a Runnable Jar File, the dependencies will be packaged within the file.
See: http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Ftasks%2Ftasks-37.htm
Also, you can select how the dependencies will be included/packaged:
