# ACCEPTANCE TEST: compile the REAL, unmodified DrussGT sources against the
# genuine Robocode 1.9.5.5 API (Approach B reuses robocode.jar instead of
# re-implementing robocode.*).
#
#   ROBOCODE_JAR=... DRUSSGT_SRC=... DRUSSGT_JAR=... ./compile_drussgt.sh
#
# Why two source files are excluded:
#   GFRange.java and Indice.java are *decompilation artefacts*. The same two
#   classes are ALSO declared inline at the bottom of DrussGunDC.java, so a
#   single javac invocation over all 22 files fails with
#   "duplicate class: jk.mega.dGun.GFRange/Indice" even with no shim at all.
#   The original DrussGT.jar already ships GFRange.class/Indice.class, so we
#   drop the redundant standalone files and let the jar supply them (together
#   with the 6 genuinely-unsourced classes: JKDCUtils, NormalDistribution,
#   StoreScan, DCRobotState, DCWave, Scan).
