Maven错误：无法找到或加载主类MyProject.jar

Question

我有一个Spring Boot应用程序，试图从Mac上的命令行运行，但出现以下错误：

Error: Could not find or load main class MyProject.jar

这是我的pom.xml

我已经在线推荐了各种帖子，并且从pom.xml上方可以看到它们，尝试添加<start-class>，spring-boot-maven-plugin，但是没有任何效果。

在链接Maven error: Could not find or load main class org.codehaus.plexus.classworlds.launcher.Launcher之后的进一步搜索中，我从M2_HOME中删除了.bash_profile，如下图所示

export M2_HOME=/Users/myuser/Downloads/apache-maven-3.5.4
export PATH=$PATH:$M2_HOME/bin

然后我使用brew安装了maven->删除了.m2文件夹->运行mvn clean install->运行java MyProject.jar

仍然面临同样的问题。有什么想法吗？
