Example of Java 9 module system non-maven

This application simply exemplifies working Module System on Java 9 and it uses some libraries such as h2 database and log4j as an example of adding the external library.

How do I compile?

You should use the javac command with the following parameters in the root directory of the project to compile the classes.

javac --module-path mods:lib \
-d mods --module-source-path src \
src/Database/module-info.java \
src/Database/src/com/kodcu/db/ConnDB.java \
src/hakdogan/module-info.java \
src/hakdogan/src/com/kodcu/InfoUser.java \
src/User/module-info.java \
src/User/src/com/kodcu/user/User.java

With find, this command can be written shorter.

javac --module-path mods:lib \
-d mods --module-source-path \
src $(find . -name "*.java")
