1、全局配置在maven的安装目录${MAVEN_HOME}/conf/找到settings.xml文件，在里面添加如下代码：<profile> <id>jdk-1.8</id> <activation> <activeByDefault>true</activeByDefault> <jdk>1.8</jdk> </activation> <properties> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion> </properties> </profile>
2、局部配置在项目中的pom.xml指定jdk版本<build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.7</version> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins></build>
