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>

<!-- 指定jdk版本，解决编译或打包时出现jdk版本未指定错误 -->
<profile>

<properties>

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>
