Question

I have 3 classes CustomerAddress, Customer and CustomerMain.

Customer has a import statement :

import org.abc.customers.CustomerAddress;

While CustomerMain has an import statement :

import org.abc.customers.CustomerAddress; 
import org.abc.customers.Customer;

The package for all of these classes are

package org.abc.customer

Now, this program works fine on eclipse but when i try to compile and run on cmd prompt it would not compile

javac CustomerAddress.java 

compiles fine

then since Customer depends on CustomerAddress

I give

javac -cp . Customer.java

but the compiler complains

error cannot find symbol CustomerAddress

Answer 1

1. Compiled classes must exist within a folder structure that matches their package structure. For example, a class com.foo.bar.A must exist within folders com/foo/bar/.
2. It really is far easier to do this sort of thing with an automated build tool like ant or maven.

If you’re determined to build from the command line, you need to compile the independant classes first:

javac -d com/abc/customers/ CustomerAddress.java Customer.java CustomerMain.java

which should compile the classes and output them somewhere that javac will be able to resolve them from.
