Java set compiling arguments

I'm having a Java project(Not so simple, with several packages and a .jar) which compile just well in Eclipse, but when I'm trying to compile it from command line I get src/Main.java:1: error: package core.simulation does not exist

This is the .classpath file:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" path="src"/>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8"/>
    <classpathentry kind="lib" path="Config.jar"/>
    <classpathentry kind="output" path="bin"/>
</classpath>

Can you explain me how to compile and run the project?(what arguments to give to javac and java). Thank you!

The javac command should know about all dependencies. Argument list should include all source file as well as reference jars. The following commands can be used for generic case:

# prepare class file output dir
mkdir -p bin

# collect all source files into list or prepare it manually
find src -iname *.java > file_list

# combine classpath by reference jars for example under lib dir
for p in $(ls lib); do cp="$cp:lib/$p"; done
# for p in $(ls lib); do cp="$cp;lib/$p"; done # for windows using ';' path separator

# compile 
javac -d bin -cp "$cp" @file_list
