#!/usr/bin/env bash
# 仅编译本仓库（maven-cw-elevator-application），依赖从 Nexus 拉取，避免使用全局 ~/.m2 里
# 其它反编译工程 mvn install 产生的同坐标覆盖。
#
# 方案要点：
# - 使用独立 maven.repo.local（默认：仓库根目录下 .m2-elevator-nexus-only），与 ~/.m2 隔离。
# - Nexus 常缺聚合父 POM cloudwalk-cloud-common：脚本会（1）尝试从全局 ~/.m2 复制该目录；
#   （2）若仍缺，且存在相邻仓库 maven-cloudwalk-legacy-public/cloudwalk-cloud-common，则自动
#   mvn -N install 到隔离库（仅父 POM，不编其它反编译模块）。
# - 私服上 cloudwalk-common-web 等 POM 若传递依赖不完整，隔离构建会缺 spring-boot / commons-lang
#   等编译包。可选（3）从全局 ~/.m2 复制 cloudwalk-common-* 同版本目录（与 Nexus 二选一：先复制则优先用本地该目录）。
# - Nexus 常缺 SNAPSHOT 父 POM（cwos / davinci）及 cloudwalk-device-sdk 父 POM：若相邻仓库存在对应 pom.xml，则自动 mvn -N install
#   到隔离库：maven-cwos-resource 的 cwos-component-resource、cwos-portal；maven-cloudwalk-intelligent-davinci-manager 根 POM；
#   maven-cloudwalk-device-sdk 根 POM（供 intelligent-cwoscomponent-interface 解析 protocol-entity）。
#   ELEVATOR_AUTO_INSTALL_LEGACY_SNAPSHOT_PARENTS=0 跳过上述「相邻父 POM install」整段。
# - intelligent-cwoscomponent 固定为 2.9.2-xinghewan（与 cw_lib 一致，禁止 3.0.0）：可先 ELEVATOR_BOOTSTRAP_INTELLIGENT_CWOSCOMPONENT_FROM_GLOBAL
#   从 ~/.m2 复制 parent（artifactId intelligent-cwoscomponent）/ interface / rest；若仍缺 JAR，则对
#   cw-elevator-application-V1.0.0.20211103/cw_lib 内同名 jar+pom 执行 install-file，并先安装 scripts/legacy-poms 下父 POM 桩。
#   ELEVATOR_AUTO_INSTALL_INTELLIGENT_CWOSCOMPONENT=0 跳过 install；ELEVATOR_CW_LIB_DIR 覆盖 cw_lib 路径。
# - cwos-sdk-event（默认 1.5.0-SNAPSHOT）：ELEVATOR_BOOTSTRAP_CWOS_SDK_EVENT_FROM_GLOBAL 从 ~/.m2 复制；缺 JAR 时对
#   maven-cloudwalk-legacy-public/cwos-sdk-event mvn install。ELEVATOR_AUTO_INSTALL_CWOS_SDK_EVENT=0 跳过 install。
# - ELEVATOR_BOOTSTRAP_FROM_GLOBAL_M2=0 跳过（1）；ELEVATOR_AUTO_INSTALL_LEGACY_PARENT=0 跳过（2）；
#   ELEVATOR_BOOTSTRAP_CLOUDWALK_MODULES_FROM_GLOBAL=0 跳过（3）（坚持纯 Nexus 时用）。
#
# 用法：
#   ./scripts/build_nexus_only.sh
#   ELEVATOR_M2_REPO=/path/to/custom-repo ./scripts/build_nexus_only.sh
#   ELEVATOR_SYNC_DEPLOY=1 ./scripts/build_nexus_only.sh   # 另同步 V1/V2 到 deploy/v1-legacy 与 deploy/v2-maven
# - 编译成功后默认将 starter fat jar 安装到 deploy/v2-maven/（覆盖 cw-elevator-application-2.0.0.jar）。
#   ELEVATOR_DEPLOY_V2_MAVEN=0 跳过；ELEVATOR_DEPLOY_V2_DIR=/path 覆盖目标目录（默认同 deploy/v2-maven）。
