在代码重构之后，当我尝试编译Maven项目时，我得到了这个错误：

我也遇到了同样的问题。强制maven-compiler-plugin使用javac帮助我发现了实际的编译错误。

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <configuration>
    <forceJavacCompilerUse>true</forceJavacCompilerUse>
  </configuration>
</plugin>

更多细节可以在Maven Compiler Plugin bug report中找到

我在编译一个项目时遇到了这个非常无用的错误，发现问题是引用了另一个类中不存在的静态内部类（它已被重命名）。一旦解决了这个问题，错误就消失了。
解决方案：查找编译错误。有时IDE可以为您找到它们，而不会引发此错误。

恭喜你，你在Java编译器中发现了一个bug。这很罕见。这是一个编译器中的bug，因为类com.sun.tools.javac.util.Assert.error清楚地表明它来自javac，Java编译器，堆栈跟踪提供了关于如何重现这个bug的很好的提示。
请将bug报告给OpenJDK项目。有compiler-dev mailing list，您可以首先询问并联系OpenJDK项目的主要开发人员。
当你报告bug时，确保你可以可靠地重现bug，并尝试通过剥离任何不必要的代码以最简单的方式重现bug。通常情况下，你最终会得到一个最多包含5个文件的项目。Here's a guide for reporting good bugs。

虽然我的回答有点晚了，但我想我的回答会对将来的人有所帮助。
我也面临着同样的问题，我发现的根本原因是
我更改了其中一个依赖项的代码，但没有更改该依赖项在pom.xml中的版本。
一旦我更新了两个pom.xml文件中的依赖项，一切就开始工作了。

我在重构后得到了这个错误，在我的例子中，崩溃是由导入一个不存在的类引起的。不幸的是，编译器和IDE没有意识到这个问题。
如果您按照@Yaroslav Buhaiev的建议启用forceJavacCompilerUse，您将看到更多有意义的错误。

使用下面的解决方案，我可以修复错误。
根本原因-特定模块内的config文件夹中存在不存在的bean类。
修复-从config文件夹中删除未使用的bean配置
示例-我从gateways模块中删除了一些类A，但bean配置仍然存在于config文件夹中。删除bean配置后，构建成功。
