SDK版本一致
右键点击项目名,打开Open Module Settings:
在项目的pom.xml中加入以下代码
<plugins>
<plugin>
<groupId>org.springframework.boot
</groupId>
<artifactId>spring-boot-maven-plugin
</artifactId>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins
</groupId>
<artifactId>maven-compiler-plugin
</artifactId>
<version>3.8.1
</version>
<configuration>
<verbose>true
</verbose>
<fork>true
</fork>
<executable>${JAVA8_HOME}/bin/javac
</executable>
</configuration>
</plugin>
</plugins>
修改settings.xml文件(\apache-maven-3.6.1\conf\settings.xml)
<profiles>
<profile>
<id>custom1-compiler
</id>
<properties><JAVA8_HOME>D:\Java\jdk8\jdk1.8.0_171
</JAVA8_HOME></properties>
</profile>
</profiles>
<activeProfiles>
<activeProfile>custom1-compiler
</activeProfile>
</activeProfiles>
完成上面步骤后,Idea会自动自成一个Profiles选项,不用管它,再次执行打包命令package即可。
