我有一个 jhipster 项目。我跑
sudo mvn clean install -U
（没有sudo，会失败，说无法删除某些文件）。
我得到输出
[INFO] --- maven-enforcer-plugin:3.0.0-M3:enforce (enforce-versions) @ jhipProj ---
[WARNING] Rule 1: org.apache.maven.plugins.enforcer.RequireJavaVersion failed with message:

我运行命令来查看 java 得到了什么
>> java --version

到底为什么我的 Maven 构建失败，它试图获取什么该死的 Java 版本？显然我正在运行 11，介于 8 和 14 之间。
您必须运行此命令： mvn --版本
检查环境变量中的 JAVA_HOME 路径。
将JAVA_HOME设置为新java版本的路径
