maven知识总结

一、maven的优势，下载，加载顺序

    a)       约定优于配置

    b)       简单

    c)       测试支持

    d)       构建简单

    e)       CI

    f)    插件丰富

    2.      下载

        a)       https://maven.apache.org/download.cgi

        b)     安装

超级pom，pom的级联关系src/main/java是在这个地方规定的

    c)       maven-model-builder-3.3.9.jar/org/apache/maven/model

    d)       配置  MVM_HOME

           i.        Windows  path

            ii.        Linux  .bash_profile

             iii.        MAVEN_OPTS

          iv.        配置setting.xml

<mirror> 

              <id>alimaven</id> 

              <name>aliyun maven</name> 

             <url>http://maven.aliyun.com/nexus/content/groups/public/</url> 

              <mirrorOf>central</mirrorOf>         

            </mirror>

            <mirror>

                  <id>ui</id>

                  <mirrorOf>central</mirrorOf>

                  <name>HumanReadable Name for this Mirror.</name>

                  <url>http://uk.maven.org/maven2/</url>

            </mirror>

            <mirror>

            <id>osc</id>

           <mirrorOf>central</mirrorOf>

           <url>http://maven.oschina.net/content/groups/public/</url>

        </mirror>

        <mirror>

            <id>osc_thirdparty</id>

           <mirrorOf>thirdparty</mirrorOf>

           <url>http://maven.oschina.net/content/repositories/thirdparty/</url>

       </mirror>

二、maven的传递依赖和作用域（转载）

三、maven仲裁管理：（转载）

四、maven 生命周期 lifecycle/phase/goal

lifecycle,phase,goal以及mojo之间的作用和区别，可以参考下面这篇博客：

https://blog.csdn.net/glory1234work2115/article/details/51570073

1.A BuildLifecycle is Made Up of Phases

2.A BuildPhase is Made Up of Plugin Goals

五、     版本管理

a)       1.0-SNAPSHOT

           i.        repository 删除

            ii.        mvn cleanpackage -U (强制拉一次)

b)       主版本号.次版本号.增量版本号-<里程碑版本>

1.0.0-RELAESE

六、   常用命令

a)      mvn clean compile

b)       mvn clean    删除target/

c)      mvn clean test       test case junit/testNG

d)        mvn clean package 打包

e)       mvn clean  install    把项目install到local repo

f)    mvn deploy   发本地jar发布到remote

七、    插件

a)       常用插件

        i.        https://maven.apache.org/plugins/

       ii.        http://www.mojohaus.org/plugins.html

     iii.        findbugs 静态代码检查

https://blog.csdn.net/Fancy_xty/article/details/51718687（idea中安装findbug插件）

<plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>findbugs-maven-plugin</artifactId> <version>3.0.0</version> <configuration> <!-- <configLocation>${basedir}/springside-findbugs.xml</configLocation> --> <threshold>High</threshold> <effort>Default</effort> <findbugsXmlOutput>true</findbugsXmlOutput> <!-- findbugs xml输出路径--> <findbugsXmlOutputDirectory>target/site</findbugsXmlOutputDirectory> </configuration> </plugin>

     iv.        versions 统一升级版本号

1.    mvnversions:set -DnewVersion=1.1

       v.        source 打包源代码（插件）

<plugin> <artifactId>maven-source-plugin</artifactId> <version>2.3</version> <executions> <execution> <id>attach-sources</id> <phase>install</phase> <goals> <goal>jar-no-fork</goal> </goals> </execution> </executions> </plugin>

      vi.        assembly 打包zip、war

       vii.        tomcat7

八、      自定义插件 https://maven.apache.org/guides/plugin/guide-java-plugin-development.html

参考文档：https://blog.csdn.net/z69183787/article/details/52982249

dependency> <groupId>org.apache.maven </groupId> <artifactId>maven-plugin-api </artifactId> <version>2.0 </version> </dependency> <dependency> <groupId>org.apache.maven.plugin-tools </groupId> <artifactId>maven-plugin-annotations </artifactId> <version>3.2 </version> <scope>provided </scope> </dependency> <dependency> <groupId>org.codehaus.plexus </groupId> <artifactId>plexus-utils </artifactId> <version>3.0.8 </version> </dependency> 一定要依赖这两个jar包

a)  <packaging>maven-plugin</packaging>

b)  extendsAbstractMojo

c)  

d)  mvn install

e)  参数传递

九、        Profile

a)  使用场景dev/test/pro

<profiles>     <profile>         <id>dev</id>         <properties>             <profiles.activation>dev</profiles.activation>         </properties>         <activation>             <activeByDefault>true</activeByDefault>         </activation>     </profile>     <profile>         <id>test</id>         <properties>             <profiles.activation>test</profiles.activation>         </properties>     </profile>     <profile>         <id>prd</id>         <properties>             <profiles.activation>prd</profiles.activation>         </properties>     </profile></profiles> build>     <finalName>winner-mvn-profile</finalName>     <resources>         <resource>             <directory>src/main/resources/${profiles.activation}</directory>         </resource>     </resources></build> mvn install -Ptest 就是打包 test/* 即test目录下的所有文件 

具体配置，参考这个博客：http://blog.51cto.com/xiaok007/1907509

b)  setting.xml 家和公司两套

4.         仓库

maven构建私服：https://blog.csdn.net/shenshen123jun/article/details/9084293

a)  下载

b)  安装 解压

c)  使用http://books.sonatype.com/nexus-book/reference3/index.html

localhost:8081,账号admin/admin123

             i.        http://192.168.1.6:8081/nexus

            ii.        admin/admin123

d)  发布

             i.        pom.xml 配置

1.   

2.   

e)  下载jar配置

             i.        配置mirror

            ii.        Profile

十、     archetype  模版化

可以参考博客：https://www.aliyun.com/jiaocheng/581611.html

a)  生成一个archetype

             i.        mvn archetype:create-from-project

            ii.        cd /target/generated-sources/archetype

          iii.        mvn install

b)  从archetype创建项目 mvnarchetype:generate -DarchetypeCatalog=local

查看系统变量：mvn help:system(idea终端窗口输入)

打包传参方式：mvn install -Dargs=123   args是一个参数名

maven统一给css,和js文件打上版本号，参考这个文档：
