How to Run Java Module class (java 9 jigsaw project) with third party library (jar files)?

Right now I'm trying to develop a Java project with pure java (no builtscript). I'm implementing the module concept from Java 9. I'm having a trouble when it comes to run a Java project (main class) with additional jar file (third party library). I have no trouble when compiling but when I try to run the java it couldn't run as expected.

I could compile this project by executing this command (javaFiles.txt contains my java files that wanted to be compiled):

javac --module-path lib -d newout --module-source-path src @javaFiles.txt

But when I try to run the compiled .class file with this command:

java --module-path newout;libs --module com.example.trial/com.example.trial.CreateProduct

I got this error as if it's a wrong command:

$ java --module-path newout;libs --module com.example.trial/com.example.trial.CreateProduct
Usage: java [options] <mainclass> [args...]
       (to execute a class) or  java [options] -jar <jarfile> [args...]
       (to execute a jar file)
...

I'm using ubuntu. Is there any other way to do it?

And also I don't really know the differences between classpath, modulepath and whatsoever. I always try to run this from module path.

I got some references from this link and this link. Those two tells me the command that I've mentioned above.

Thank you!

The path separator in all non-Windows systems is colon (:), not semicolon (;). You need to change this:

java --module-path newout;libs

to this:

java --module-path newout:libs

Unix shells use ; to separate two consecutive commands. So your original line was actually trying to execute these two commands:

$ java --module-path newout
$ libs --module com.example.trial/com.example.trial.CreateProduct
