Creating an uber jar for Spring

This is a follow up to this question: creating an uber jar with spring dependencies

I have created a web service using Eclipse, which is running on Windows. I need to run it as a jar on a Solaris station and there I get the ClassNotFoundException:

Caused by: java.lang.ClassNotFoundException: org.springframework.boot.SpringApplication at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358

I want to create a big jar with all dependencies but I don't understand the answer to that question above.. where do I add what he wrote? And then do I just need to export a jar as usual using Eclipse's export option?

What no one ever said in the answers to other questions is that you need to use maven to create the jar and not using Eclipse's export to jar option. What you need to do is:

1) download maven from https://maven.apache.org/download.cgi

2) The maven dir contains a 'bin' folder. Add this folder to your "path" enviornment variable (on Windows 8 right click "This PC" -> properties -> Advanced System Settings -> Environment Variables -> in System Variables find "Path" -> double click it and add it by adding the bin folder path to that variable the same way other paths are located there.

3) open CMD

4) navigate to your project's folder

5) type mvn package

The jar file is created inside the "target" folder.

Good luck
