java - 在maven中编译问题

Question

当我使用命令-mvn install时，我遇到了这样的问题。问题是

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:testCompile (default-testCompile) on project Demo: Compilation failure
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

我在我的工作区中运行我的程序，默认情况下仅 jre1.8，但对于之前的程序，它运行成功。仅此一点我就面临问题!

我的POM文件

尝试设置环境变量JAVA_HOME指向jdk。 https://docs.oracle.com/cd/E19182-01/820-7851/inst_cli_jdk_javahome_t/

此外，尝试将 Maven 编译器插件设置为您正在使用的编译器版本。
