Java - Build and run eclipse project from command line

I have a java project written using eclipse ide and I want to run it through ssh on a different machine, but I have to do this using the command line and I don't know exactly how.

I am a beginner at both shell commands and java.

Could you please give me a useful link with answers regarding this question, or perhaps a set instructions of how to do this?

Maven or Ant are the best option but for an Eclipse-only solution
you can choose File -> Export and select Java -> Runnable JAR File
then transfer the JAR file to your other machine and run this from the command line:

java -jar YOUR.JAR

You can run Java applications from the command line. The simplified syntax looks like this:

java -cp <classpath> <main class> <args>

where:

<classpath> - list of directories and/or JAR-files where needed classes reside separated by ";" for Windows or ":" for linux (default classpath is "." - the current directory);

<main class> - fully qualified name of the class containig main() method (for example, org.myself.HelloWorld)

<args> - various arguments for application if any.

So, if you find the directory where Eclipse stored compiled classes (usually it's bin) you may use the command, like

java -cp . my.package.MyClass

Or, if you use some libraries and classes in other directories, it could be:

java -cp some-cool-lib.jar:another-lib.jar:/some/directory/with/classes my.package.MyClass

To build and run a Java project, Its good to use an ant or maven tool. you can find many tutorials on google for the same.

a good tutorial on ant is here http://www.intranetjournal.com/java-ant/

This is what I did and it worked for me. Hope it could help.
