maven本地配置及pom.xml配置解决未指定jdk版本错误

一、maven本地配置

<?xml version="1.0" encoding="UTF-8"?><settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"><!-- 本地仓库地址 --><localRepository>E:\MavenRepo\repository</localRepository><!-- 是否使用本地仓库（先从本地查找依赖，如果没有再使用远程仓库） --><interactiveMode>true</interactiveMode><!-- 是否离线（如果为true则只从本地仓库查找依赖） --><offline>false</offline><pluginGroups></pluginGroups><proxies></proxies><servers></servers><mirrors><mirror><id>alimaven</id><name>aliyun maven</name><url>http://maven.aliyun.com/nexus/content/groups/public/</url><mirrorOf>central</mirrorOf></mirror><mirror><id>ali-maven</id><mirrorOf>central</mirrorOf><name>aliyun maven</name><url>http://maven.aliyun.com/nexus/content/repositories/central/</url></mirror><mirror><id>central</id><name>Maven Repository Switchboard</name><url>http://repo1.maven.org/maven2/</url><mirrorOf>central</mirrorOf></mirror><mirror><id>repo2</id><mirrorOf>central</mirrorOf><name>Human Readable Name for this Mirror.</name><url>http://repo2.maven.org/maven2/</url></mirror><mirror><id>ibiblio</id><mirrorOf>central</mirrorOf><name>Human Readable Name for this Mirror.</name><url>http://mirrors.ibiblio.org/pub/mirrors/maven2/</url></mirror><mirror><id>jboss-public-repository-group</id><mirrorOf>central</mirrorOf><name>JBoss Public Repository Group</name><url>http://repository.jboss.org/nexus/content/groups/public</url></mirror><!-- 中央仓库在中国的镜像 --><mirror><id>maven.net.cn</id><name>oneof the central mirrors in china</name><url>http://maven.net.cn/content/groups/public/</url><mirrorOf>central</mirrorOf></mirror><!-- apache --><mirror><id>apache</id><name>apache mirrors</name><url>http://repository.apache.org/content/groups/public/</url><mirrorOf>central</mirrorOf></mirror><mirror><id>apache-snapshots</id><name>apache-snapshots-mirrors</name><url>http://repository.apache.org/content/groups/snapshots/</url><mirrorOf>snapshots</mirrorOf></mirror></mirrors><profiles><!-- 指定jdk版本，解决编译或打包时出现jdk版本未指定错误 --><profile> <id>custom-compiler</id>              <properties>                  <JAVA8_HOME>D:\Java\jdk1.7.0_80</JAVA8_HOME>                <JAVA7_HOME>D:\Java\jdk1.8.0_121</JAVA7_HOME>                <JAVA6_HOME>D:\Java\jdk1.6.0_43</JAVA6_HOME>            </properties>  </profile></profiles><activeProfiles>          <activeProfile>custom-compiler</activeProfile>  </activeProfiles>  </settings>

二、maven项目的pom.xml配置

如下面配置，采用jdk7作为项目默认jdk编译版本

<build><pluginManagement><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.6.2</version><configuration><source>1.7</source><target>1.7</target><compilerVersion>1.0</compilerVersion><verbose>true</verbose>          <fork>true</fork>         <executable>${JAVA7_HOME}/bin/javac</executable>  </configuration></plugin></plugins></pluginManagement></build>
