bash
# 在父项目根目录执行
# 清理所有模块
mvn clean
# 编译所有模块
mvn compile
# 测试所有模块
mvn test
# 打包所有模块
mvn package
# 安装所有模块到本地仓库
mvn install
# 只构建特定模块
mvn clean install -pl my-project-service
# 构建特定模块及其依赖
mvn clean install -pl my-project-web -am
# 跳过测试构建
mvn clean install -DskipTests
# 并行构建（提高构建速度）
mvn clean install -T 4🎛️ 9. Profile 配置管理
Profile允许为不同的环境或条件定制构建过程。
9.1 Profile 基本概念
🎯 Profile的作用：
- 为不同环境提供不同的配置
- 根据条件激活不同的构建行为
- 管理不同的依赖和插件配置
9.2 Profile 配置详解与实战案例

bash
# ==================== 命令行激活 ====================
# 1. 激活单个Profile
mvn clean install -Pdev
mvn clean install -P dev # 空格也可以
# 2. 激活多个Profile
mvn clean install -Pdev,test,integration-tests
mvn clean install -P dev,test,integration-tests
# 3. 排除特定Profile
mvn clean install -P !prod # 排除prod Profile
mvn clean install -P dev,!test # 激活dev，排除test
# ==================== 属性激活 ====================
# 4. 通过系统属性激活
mvn clean install -Denv=test # 激活基于env属性的Profile
mvn clean install -DrunIntegrationTests=true # 激活集成测试Profile
mvn clean install -Ddebug # 激活基于debug属性存在的Profile
# 5. 通过Maven属性激活
mvn clean install -Dmaven.test.skip=true -Pfast-build
# ==================== 环境变量激活 ====================
# 6. 设置环境变量
export ENV=prod
mvn clean install # 自动激活基于ENV环境变量的Profile
# Windows环境
set ENV=prod
mvn clean install
# 7. 临时环境变量
ENV=test mvn clean install # Linux/Mac
set ENV=test && mvn clean install # Windows
# ==================== 查看Profile信息 ====================
# 8. 查看当前激活的Profile
mvn help:active-profiles
mvn help:active-profiles -Pdev,test
# 9. 查看所有可用的Profile
mvn help:all-profiles
# 10. 查看有效POM（包含Profile效果）
mvn help:effective-pom -Pdev > effective-pom-dev.xml
# 11. 查看有效设置
mvn help:effective-settings
# ==================== 高级激活技巧 ====================
# 12. 条件激活组合
mvn clean install -Pdev -DskipTests=false -Dspring.profiles.active=dev
# 13. 基于文件存在激活
# 如果存在docker-compose.yml文件，自动激活docker Profile
mvn clean install # 自动检测文件存在性
# 14. 基于JDK版本激活
mvn clean install # 自动根据当前JDK版本激活对应Profile
# 15. 基于操作系统激活
mvn clean install # 自动根据操作系统激活对应Profile💡 Profile激活实战案例

Maven仓库是存储项目依赖和插件的地方，分为本地仓库、中央仓库和远程仓库。
10.1 仓库类型详解
🏠 本地仓库（Local Repository）
- 位置：
~/.m2/repository - 作用：缓存从远程仓库下载的依赖
- 优先级：最高
🌐 中央仓库（Central Repository）
- 地址：repo1.maven.org/maven2/
- 作用：Maven官方维护的公共仓库
- 特点：包含大部分开源项目的依赖
🔗 远程仓库（Remote Repository）
- 作用：企业私有仓库或第三方仓库
- 配置：在pom.xml或settings.xml中配置
10.2 仓库配置
📝 在pom.xml中配置仓库

13.1 常见问题及解决方案
❌ 问题1：依赖下载失败
bash
# 错误信息
[ERROR] Failed to execute goal on project my-project:
Could not resolve dependencies for project com.example:my-project:jar:1.0.0
# 解决方案
# 1. 检查网络连接
# 2. 清理本地仓库
rm -rf ~/.m2/repository/com/example/problematic-dependency
# 3. 强制更新
mvn clean install -U
# 4. 检查仓库配置
mvn help:effective-settings❌ 问题2：编译错误
bash
# 错误信息
[ERROR] COMPILATION ERROR :
[ERROR] Source option 8 is no longer supported. Use 11 or later.
# 解决方案
# 1. 检查Java版本
java -version
mvn -version
# 2. 更新编译器配置
<properties>
<maven.compiler.source>11</maven.compiler.source>
<maven.compiler.target>11</maven.compiler.target>
</properties>
# 3. 或者使用插件配置
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.11.0</version>
<configuration>
<source>11</source>
<target>11</target>
</configuration>
</plugin>❌ 问题3：内存不足
bash
# 错误信息
[ERROR] Java heap space
[ERROR] OutOfMemoryError
# 解决方案
# 1. 设置Maven内存参数
export MAVEN_OPTS="-Xmx2048m -Xms1024m -XX:MaxPermSize=512m"
# 2. Windows环境
set MAVEN_OPTS=-Xmx2048m -Xms1024m
# 3. 在IDE中设置
# IntelliJ IDEA: File -> Settings -> Build -> Build Tools -> Maven -> Runner
# Eclipse: Run Configurations -> Maven Build -> JRE -> VM arguments❌ 问题4：插件版本冲突
bash
# 错误信息
[ERROR] Plugin org.apache.maven.plugins:maven-compiler-plugin:2.3.2
or one of its dependencies could not be resolved
# 解决方案
# 1. 显式指定插件版本
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.11.0</version>
</plugin>
# 2. 使用pluginManagement统一管理
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.11.0</version>
</plugin>
</plugins>
</pluginManagement>13.2 调试技巧
bash
# 1. 开启调试模式
mvn clean install -X
# 2. 查看详细错误信息
mvn clean install -e
# 3. 分析依赖冲突
mvn dependency:tree -Dverbose
# 4. 检查有效POM
mvn help:effective-pom > effective-pom.xml
# 5. 验证项目配置
mvn validate
# 6. 检查插件配置
mvn help:describe -Dplugin=compiler -Ddetail🏆 14. 最佳实践
