spring-boot之错误 不再支持源选项 1.5。使用1.6或更高版本

这一切都发生在我尝试通过 ./mvnw clean install 构建 springboot 应用程序时

当我第一次运行安装命令时，遇到以下问题。

我在 Stackoverflow 上搜索了这个问题，并通过帖子解决了这个问题

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile)

然后，我遇到了另一个问题

[ERROR] Source option 1.5 is no longer supported. Use 1.6 or later. 
[ERROR] Target option 1.5 is no longer supported. Use 1.6 or later. 

我使用的是 OS X。mvn -v 显示:

Maven home: /Users/matthuntington/Desktop/apache-maven-3.5.0 
Java version: 9, vendor: Oracle Corporation 
Java home: /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home 
Default locale: en_US, platform encoding: UTF-8 
OS name: "mac os x", version: "10.12.6", arch: "x86_64", family: "mac" 

这是我的 pom 文件

请您参考如下方法:

您可以通过将这些属性添加到 pom.xml 文件来指定 Maven 源/目标版本

<properties> 
    <maven.compiler.source>1.6</maven.compiler.source> 
    <maven.compiler.target>1.6</maven.compiler.target> 
</properties>
