compiling a large package...

Thread view:

I'm trying to compile src code for a large package I downloaded, all of
a sudden I'm realizing after compiling I have all the classes in same
folders where .java files are.. is there a way to separate src files
from classes to turn entire package back into a jar file? (or is it ok
to convert to a jar file if source files are in same dirs w/the
classes?) I've never had to compile a large package like this before..

guy who wrote package has been helping me a bit, he says to compile
entire package by doing "javac nu\fw\jeti\backend\Start.java"
(I don't understand how compiling Start.java compiles entire package...)

but not all .java files in package get compiled..

files here

nu\fw\jeti\plugins\emoticons

get compiled, but not here...

nu\fw\jeti\plugins\alertwindow

(and how come files in nu\fw\jeti\plugins\emoticons DO get compiled
when command to compile was "nu/fw/jeti/backend/Start.java

this is basically for an applet I dl'd that we need here at work, can't
use if can't re-compile all source code.. (b/c will need to change some
things..)

what way is there to compile entire package... and then separate all
src code from class files so I can convert back to a jar file.. this
project is of more complexity and I have knowledge for and well, if
anybody can point me to places where I can find out how to do this that
would be great... (I dl'd ANT once, couldn't figure out how to use it, I
will try again... but well, is ANT the only way? or can this be done
"by hand"?) thank you.. Frances

You can tell javac where to get the source files and where to put the class
files.

If javac can't find a class file for a class mentioned in Start.java, it will
search for a source file and compile that. Recursively.

Don't be afraid to use your brain.

You could try to write a simple shell script that does all the work for you.

Lets say you have directory A with a buch of *.java files.
To compile them all use javac *.java -d B
where B is the directory where all your classes will go, this will
compile all your java source code.

file directory
A
-aClass.java
-bClass.java
-B
--aClass.class
--bClass.class

That should work.
