# E2E Integration Test Script for Cross-Repository Dependency Linking (v1.5.0)
#
# This script tests cross-repo dependency linking via build system analysis:
# 1. Spins up isolated Neo4j and Qdrant instances on high ports (18xxx/16xxx)
# 2. Indexes a library repo (auth-lib) with pom.xml declaring Maven GAV
# 3. Indexes a client repo (client-app) with pom.xml declaring dependency on auth-lib
# 4. Verifies DEPENDS_ON edge between repositories
# 5. Tests knot deps CLI subcommand (forward and reverse)
# 6. Tests list_repo_dependencies MCP tool
# 7. Tests cross-repo find_callers
# 8. Cleans up containers and data
#
# Usage: ./tests/run_cross_repo_dep_e2e.sh
# Requirements: docker, docker-compose
