代码重构后，当我尝试编译 Maven 项目时，出现此错误：

我尝试删除文件夹

更多详细信息可以在这个 Maven 编译器插件错误报告
中找到编辑：该问题已在
maven-compiler-plugin我在编译项目时遇到了这个非常无用的错误，并发现问题是对另一个类中不存在的静态内部类的引用（它已被重命名）。一旦解决，错误就消失了。
解决办法：查找编译错误。有时您的 IDE 可能能够为您找到它们，而不会引发此错误。
恭喜，您发现了 Java 编译器中的错误。那是很少见的。这是编译器中的一个错误，因为类
com.sun.tools.javac.util.Assert.errorjavac请将错误报告给 OpenJDK 项目。您可以在 compiler-dev 邮件列表 中首先询问并联系 OpenJDK 项目的主要开发人员。
当您报告错误时，请确保您可以可靠地重现该错误，并尝试通过剥离任何不必要的代码以最简单的方式重现该错误。通常，您最终会得到一个最多包含 5 个文件的项目。 这是报告良好错误的指南。
参加聚会迟到了，但我想我的回答会对将来的某人有所帮助。
我也遇到了同样的问题，但更改本地依赖项的版本解决了我的问题。
project-a 是project-b 的依赖项。当我更改了project-a代码并且没有更新project-b中的版本时，问题就出现了。
一旦我更新了两个 pom.xml 文件中的依赖关系，一切就开始工作了。
以上是根本原因之一，但您可能会遇到不同的情况。
我在重构后遇到了这个错误，在我的例子中，崩溃是由导入不存在的类引起的。 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。
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile
(default-compile) on project reporting: Compilation failure: Compilation failure:
[ERROR] /Users/myuser/projects/myproject//src/main/java/com/example/UserResource.java:[76,111]
error: cannot find symbol
[ERROR] symbol: variable MY_PARAM
[ERROR] location: class UserRepository
通过以下解决方案，我能够修复错误。
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 - 从配置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 A 类，但 bean 配置仍然存在于 config 文件夹中。删除bean配置后，构建成功。
