maven JDK版本配置

apache-maven-x.x.x\conf\settings.xml文件添加如下配置

<?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"

maven配置

项目pom.xml中jdk版本配置(不配置使用maven中setting.xml的默认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>
