Failure executing javac, but could not parse the error: How to find which source file caused error?
我知道还有其他几个问题，有人遇到了问题，因为他们在编译时遇到了类似的错误，但这并不是完全相同的错误。在他们的例子中，问题似乎是 Maven 没有正确编译器的路径。在我的例子中，问题似乎是某处写错了 class/type。
编译结果：
COMPILATION ERROR :

ErrorType (https://docs.oracle.com/javase/7/docs/api/javax/lang/model/type/ErrorType.html) 表示某种 class 或接口等未正确编写且无法建模。
ArrayType 只是表示它是一个数组。所以很可能这意味着我在某个地方使用 incomplete/missing class 作为数组。
这也是在 visitMethodDef() -> validateAnnotatedType() 中，这意味着这可能是方法的 return type/parameter？
这可能是什么原因造成的？为什么编译器不说明这发生在源代码中的什么位置？
我正在使用 Maven 2.4 和 JDK 1.8。我编译一般没有问题。
这是我的 Maven pom.xml 文件的片段：

</properties>
我也尝试使用 Maven 的更多输出进行编译，但我没有看到任何对检测错误有用的信息。
为什么编译器不显示不完整类型在哪个文件中？我怎样才能以显示哪个文件有错误的方式进行编译？是否可以验证单个文件以发现此类错误？
一个 simillair 错误在这里有一个错误报告（https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=2ahUKEwix2evZmt3cAhXoNJoKHWQ7BXAQFjABegQICRAB&url=https%3A%2F%2Fnetbeans.org%2Fbugzilla%2Fshow_bug.cgi%3Fid%3D247421&usg=AOvVaw3ulnafW3ET1VWqw43wAEC0）有人试图合并 Lists/arrays 但语法不正确。但是有没有办法找出哪个文件包含错误？
我找到问题所在了。
我有一个方法声明：
public synchronized static T[] <T> foo(...)
而不是
public synchronized static <T> T[] foo(...)
令人难以置信的是，编译器甚至没有说明它是哪个源文件。
