Backport of #12546 to the 3.9.x branch. Adapted for the different script location (src/bin/mvn vs src/assembly/maven/bin/mvn), the simpler jvm.config handling (no JvmConfigParser on this branch), and jansi-native instead of jline-native. Key changes: - Detect MSYS2 (MSYS_NT-*) alongside MinGW in uname matching - Guard against missing cygpath(1) — warn and fall back to POSIX paths - Convert all paths (MAVEN_HOME, CLASSWORLDS_JAR, MAVEN_PROJECTBASEDIR, jansi-native) for both Cygwin and MinGW/MSYS2, not just Cygwin - Convert jansi-native path separately to avoid mixed separators - Use printf instead of echo for values holding paths (avoid backslash expansion in dash/ash) - Add shell test covering Cygwin, MinGW, MSYS2, and missing-cygpath fallback, wired into the build via exec-maven-plugin Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

LGTM — clean backport of #12546 to maven-3.9.x. Correctly adapted for the 3.9.x branch differences: src/bin/mvn script location, no JvmConfigParser, and jansi-native instead of jline-native. Same core improvements as the master and 3.10.x versions: MSYS2 detection, cygpath guard, printf-over-echo for paths, comprehensive test script with macOS $TMPDIR normalization.
