maven里面pom文件的各标签介绍
由于maven在工作中经常使用，但是平时要记的知识点有点多，偶尔回头来看一些东西难免忘记，特此整理一篇笔记，方便大家搜索查询，也方便自己以后查询！
后续碰见其他的标签也会进行更新！
maven的pom文件中存在引入依赖、声明、继承；引入依赖的时候首先去本地仓库找，找不到再去配置的其他仓库找！
1.modelVersion
<modelVersion>4.0.0</modelVersion><!--描述这个POM文件是遵从哪个版本的项目描述符。-->
2.parent
<parent><!--父级依赖，继承-->
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.2.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
3.dependencies
<dependencies><!--引入依赖-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>
</dependencies>
4.dependencyManagement
<!--声明依赖，如果dependencies中没有声明版本就会来这里面找-->
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Finchley.BUILD-SNAPSHOT</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
5.repositories
<!-- <!–相当于配置远程仓库–> <repositories> <repository> <id>spring-snapshots</id> <name>Spring Snapshots</name> <url>https://repo.spring.io/libs-snapshot</url> <!–是否自动更新–> <snapshots> <enabled>true</enabled> </snapshots> </repository> <repository> <id>spring-milestones</id> <name>Spring Milestones</name> <url>https://repo.spring.io/libs-milestone</url> <snapshots> <enabled>false</enabled> </snapshots> </repository> <repository> <id>spring-releases</id> <name>Spring Releases</name> <url>https://repo.spring.io/libs-release</url> <snapshots> <enabled>false</enabled> </snapshots> </repository> </repositories>
6.properties
<properties><!--定义的标签属性可以在其他地方读取-->
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<start-class>eureka.EurekaApplication</start-class>
<java.version>1.8</java.version>
<docker.image.prefix2></docker.image.prefix2>
</properties>
7.pluginRepositories
<!–插件仓库–>
<pluginRepositories>
<pluginRepository>
<id>spring-snapshots</id>
<name>Spring Snapshots</name>
<url>https://repo.spring.io/libs-snapshot-local</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
</pluginRepository>
<pluginRepository>
<id>spring-milestones</id>
<name>Spring Milestones</name>
<url>https://repo.spring.io/libs-milestone-local</url>
<snapshots>
<enabled>false</enabled>
</snapshots>
</pluginRepository>
</pluginRepositories>-->
8.配置jdk版本
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
打包相关
<resources>
<resource>
<!-- 指定资源文件位置 -->
<directory>src/main/resources</directory>
<!-- 处理文件时，需要对文件进行变量替换 -->
<filtering>true</filtering>
<excludes>//指定需要排除的文件
<exclude>application-dev.properties</exclude>
<exclude>application-prod.properties</exclude>
<exclude>application-test.properties</exclude>
<exclude>logback-prod.xml</exclude>
</excludes>
</resource>
<resource>
<!-- 指定资源文件位置 -->
<directory>src/main/resources</directory>
<!-- 处理文件时，需要对文件进行变量替换 -->
<filtering>true</filtering>
<includes>//指定需要包含的文件
<include>application.properties</include>
<include>lib/**</include>
<include>application-${profiles.active}.properties</include>
<include>logback-${profiles.active}.xml</include>
</includes>
</resource>
</resources>
plugins定义插件

<execution>
<goals>
<goal>repackage</goal> <!-- 可以打包成可执行的 JAR -->
</goals>
<configuration>
<layout>ZIP</layout>
<includes>
<include>
<groupId>non-exists</groupId>//打包将依赖包移除在外，如果有需要一起打包的则填上对应的jar包groupId
<artifactId>non-exists</artifactId>
</include>
</includes>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
<plugin>

<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>target/lib</outputDirectory>//将所有依赖复制到这个目录
<excludeTransitive>false</excludeTransitive>
<stripVersion>false</stripVersion>
<includeScope>runtime</includeScope>
</configuration>
</execution>
</executions>
</plugin>
//打包将静态资源文件排除
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <configuration> <!-- <excludes> <exclude>lib/**</exclude> <exclude>**/*.properties</exclude> <exclude>**/*.xml</exclude> <exclude>**/*.yml</exclude> <exclude>**/*.txt</exclude> <exclude>static/**</exclude> <exclude>templates/**</exclude> <exclude>public/**</exclude> <exclude>public-v3/**</exclude> <exclude>public-v3-prod/**</exclude> <exclude>public-v3-test/**</exclude> </excludes>--> <includes> <include>com/**</include> </includes> </configuration> </plugin>
移动、复制、删除等相关操作
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-antrun-plugin</artifactId> <executions> <execution> <phase>package</phase> <goals> <goal>run</goal> </goals> <configuration> <target> <taskdef resource="net/sf/antcontrib/antcontrib.properties" classpathref="maven.runtime.classpath" /> <property name="dist">target/${project.artifactId}</property><!--target/syh-prom-h5--> <property name="res">target/${project.artifactId}/resources</property><!--target/syh-prom-h5/resources--> <property name="app-name">${project.artifactId}-${project.version}</property> <property name="real-app-name">${project.artifactId}</property> <mkdir dir="${dist}" /><!--创建文件--> <mkdir dir="${res}" /> <move file="target/${app-name}.jar" tofile="${dist}/${real-app-name}.jar" /><!--移动文件指定目录重命名--> <move todir="${dist}/lib"><fileset dir="target/lib" /></move><!--将target/lib移动至{dist}/lib--> <copy todir="${res}"> <fileset dir="target/classes"> <include name="lib/**" /> <include name="**/*.properties" /> <include name="**/*.xml" /> <include name="**/*.yml" /> <include name="**/*.txt" /> </fileset> </copy> <tar destfile="target/${real-app-name}.tar" basedir="${dist}"/><!--压缩成tar--> <gzip destfile="target/${real-app-name}.tar.gz" src="target/${real-app-name}.tar"/><!--压缩成.gz--> <delete> <fileset dir="target" includes="*.tar"/><!--删除文件--> <fileset dir="target" includes="*.original"/> </delete> </target> </configuration> </execution> </executions> </plugin>
