In Class A I import other classes from the other packages
I compiled as follows: package per package
javac-classpath / home/researcher/file1.jar:/home/researcher/file2.jar:/home/ researcher/src *. java
-> It works (i have the. Class in each package)
I run as follows:
cd /home/researcher/project/src/A
java-cp / home/researcher/file1.jar:/home/researcher/file2.jar:/home/researcher /src Main
it does not work! have you any idea?

Exception in thread "main" java.lang.NoClassDefFoundError: Main
