Mvn clean包提供了意外的java.lang.AssertionError

Question

我试图对我的Maven Springboot项目执行MVN clean包，但我看到以下消息。原因会是什么呢？我已经在网上搜索了所有的东西；这是一个常见的情况，但没有人有一个明确的解决办法，可以对我有用。

真的，问题的原因是没有一个文件夹或包吗？或者这第二行只是与JavaCompilerForce选项本身相关，而与应用程序的核心无关？看来我太奇怪了。而且，在add中，完全相同的应用程序可以在另一台电脑上完美运行。

感谢所有的时间，我认为，问题是缺少一些组件。我尝试添加这些，但现在错误消息被更改了。在这一点上，我有点麻烦了，因为我看到了这个maven输出：

[ERROR] /home/user/Desktop/mycompany/myapp/server/src/main/java/com/mycompany/myapp/representation/rest/RestControllerAdvice.java:[8,38] error: cannot find symbol
[ERROR]   symbol:   class InvalidPropertyValueException
[ERROR]   location: package com.mycompany.myapp.exception

import org.springframework.web.bind.annotation.ExceptionHandler;

import com.mycompany.myapp.exception.InvalidPropertyValueException;

奇怪的是，在com.mycompanny.myapp.exception包中，我没有找到任何名为InvalidPropertyValueException的类或文件。但Eclipse接受它并将我显示在选项列表中。并且该类不会生成任何错误或红线。
