Project Structure

The server is split into independent Ant projects, each producing its own class output. They share a classpath at build time — the Engine depends on Core, not the reverse.

Build Output

L2JEvolution.HighFive/bin/   →  core .class files
L2JEvolution.Engine/bin/     →  engine .class files
lib/                         →  shared JAR dependencies

Both bin/ directories are placed on the JVM -cp at runtime.
