Compiling java program with JARs and resource folder

Question

I want to compile my Java program in command line. Until now, NetBeans have been doing this job for me.

My program consists of:

/program/
        /src/mypacket/
                     /klass1.java
                     /...
        /src/Main.java
        /resources/
                  /img1.png
                  /...
        /lib/
            /jar1.jar
            /...

Unfortunately, I am not able to build a proper command. My efforts resulted in sth like:

javac -classpath lib/*.jar src/mypacket/*.java src/Main.java

In result I get ~20 errors similar to:

src/mypacket/myclass.java:4: error: The import xyz.zyx cannot be resolved

What do I do wrong?

all imports are from lib? aren't there libraries referenced indirectly from lib jars that you need to provide in classpath? — gunar

Classpath should be lib/one.jar:lib/two.jar but your shell expands it to lib/one.jar lib/two.jar.

I assumed that you are using Linux, Unix or MacOs because of using slash and *. If it is not true, shout.

dir/*.ext works in Windows too, since at least Windows XP. You should probably note in your answer that the path separator char in Windows is ;.
