      • eclipse:eclipse # 生成或转化成eclipse工程
      • eclipse:clean # 清除eclipse设置

      • install # compile, package后， 保存到本地仓库
        • X # 显示依赖
        • Dmaven.test.skip=true # 跳过测试

  • 常用
    • 分析包依赖
      • mvn dependency:tree -Dverbose -Dincludes=org.apache.commons:commons-lang3
    • 清理打包文件
      • mvn clean package -DskipTests
    • idea工具
      • 打包了带main方法的jar不能引用
      • 在父项目运行mvn package, model中运行会找不到其它model
      • model运行前先mvn package
    • 手动添加依赖
      • mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc7 -Dversion=12.1.0.2 -Dpackaging=jar -Dfile=ojdbc7.jar
  • 配置
    • <groupId> # 包名 - <artifactId> # 项目名 - <version> - <packaging> # 打包方式, war, jar - <parent> # 父模块 - <properties> - <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> - <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> - <java.version>1.8</java.version> - <spring-cloud.version>Dalston.RELEASE</spring-cloud.version> - </properties> - <dependencies> # 子模块继承 - <dependency> - <groupId> - <artifactId> - <version> - LATEST - ${spring-cloud.version} 引用properties中定义的变量 - <scope> # 何时使用 - compile - provided # 类似compile - runtime - test - system

    • 介绍
      • 按顺序执行，完成maven生命周期
      • 无配置时调默认插件
    • 生命周期(lifecycle)顺序
      • clean # 清除target目录
      • resources # 复制resources下文件到target/classes
      • complie # 包含resources, 编译java下文件到target/classes
      • testResources # 复制test/resources下文件到target/test-classes
      • testCompile # 包含testResources, 编译test/java下文件到target/test-classes
      • test # 包含resources, compile, testResources, testCompile, test
      • package
      • jar # 打包class文件, 配置文件, 不打包lib

    • ojdbc14本地加载
      • ＃ oracle是收费的，所以不能直接下载到驱动
      • o→ mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc14 -Dversion=10.2.0.4.0 -Dpackaging=jar -Dfile=ojdbc14-10.2.0.4.0.jar
      • o→ 把ojdbc14-10.2.0.4.0.jar复制到目录下: /home/outrun/.m2/repository/com/oracle/ojdbc14/10.2.0.4.0/
      • o→ /home/outrun/.m2/repository/com/oracle/ojdbc14/下会产生maven-metadata-local.xml文件存放maven引入依赖
      • o→ 项目中引入本地依赖
        • <dependency> - <groupId>com.oracle</groupId> - <artifactId>ojdbc14</artifactId> - <version>10.2.0.4.0</version> - </dependency> - 代理
