is because of spring-boot-maven-plugin ? and even tried

java -cp  libs/myExample-1.0-SNAPSHOT.jar: BOOT-INF.classes.com.manish.myexample.Example

Answer 1

You must ensure that you add the location of your .class file to your classpath. That is usually first mistake.

...and some general reasons why Java cannot find the class:

1. you made a mistake with the classname argument;
2. the application's classpath is incorrectly specified: the wrong directory is on the classpath, the subdirectory path doesn't match or dependencies missing from the classpath;
3. the class has been declared in the wrong package.
