我在尝试启动 jetty 时遇到以下问题，出现以下异常：

从我读到的内容来看，问题似乎是 lambda 破坏了 guice 错误处理，但人们仍然没有想出解决方案。如果有人知道这是关于什么的，请 post 发表评论！

Answer 1

当您的一个 guice 模块中的配置错误并且您正在使用 Java 8 lambdas 和 guice 3 时，会发生此不可读的异常。

我在这个问题上花了很多时间。每次，我都通过升级到 guice 4 beta 来解决问题。它的特点之一是：

Better Java8 runtime compatibility

如果你使用maven:

<dependency>
  <groupId>com.google.inject</groupId>
  <artifactId>guice</artifactId>
  <version>4.0-beta5</version>
</dependency>

这个新版本会给你一个明确的错误信息和一个适当的堆栈跟踪，让你找到问题。解决后，您可以切换回 guice 3.0 或继续使用 4.0-beta（据我所见，它已经稳定）。

注意guice 4.0 and 4.1 have been released。所以你应该使用最新版本：

<dependency>
  <groupId>com.google.inject</groupId>
  <artifactId>guice</artifactId>
  <version>4.1.0</version>
</dependency>

Why is a lambda expression breaking guice error handling when i try to start jetty?

java

lambda

java-8

guice

guice-3
