Compiling multiple packages using the command line in Java

Question

Hi i have been using an IDE but now I need to run and compile from the command line.

The problem is that I have multiple packages and I have tried to find the answer but nothing has worked.

So I have

src/
  Support/ (.java files)
  Me/ (.java files) 
  Wrapers/ (.java files)  

Do you know how to compile everything with javac?

Answer 1

This should do it (may require additional classpath elements via the -cp command line switch):

javac Support/*.java Me/*.java Wrapers/*.java

But if your build process gets more complex (and it will!), you should look into using Apache Ant for build automation.
