Question

我们的maven build在jetty关闭的构建结束时抛出一个我不明白的NoClassDefFoundError。有没有人知道这是从哪里来的，以及如何解决它？

有时堆栈跟踪会有所不同，而且会出现这种情况：

Answer 1

请注意，一些其他示例将使您向jersey-container-jetty-http添加maven依赖项，其中包括可能较旧版本的jetty http。如果您已经拥有jetty-server dep，请删除该依赖项。在你的pom文件中。

Answer 2

您的环境中似乎有两个版本的Jetty。

您的mvn dependency:tree在<scope>compile</scope>依赖项中显示以下内容。

[INFO] com.company:our.endpoint.test:jar:1.0.0-SNAPSHOT
[INFO] +- com.restfuse:com.eclipsesource.restfuse:jar:1.0.0:compile
[INFO] |  +- org.mortbay.jetty:jetty-j2se6:jar:6.1.26:compile
[INFO] |  |  \- org.mortbay.jetty:jetty:jar:6.1.26:compile
[INFO] |  |     +- org.mortbay.jetty:jetty-util:jar:6.1.26:compile
[INFO] |  |     \- org.mortbay.jetty:servlet-api:jar:2.5-20081211:compile

这里有两个问题。

首先，restfuse似乎是旧的，非常古老，并且想要Jetty 6.1.26。（这个版本的Jetty在2007年是EOL /生命终结）

其次，当jetty-maven-plugin正在运行时，此版本可能会影响应用程序的行为。

为Jetty 6添加一个排除项，然后尝试一下。

<dependency>
  <groupId>com.restfuse</groupId>
  <artifactId>com.eclipsesource.restfuse</artifactId>
  <version>1.0.0</version>
  <exclusions>
    <exclusion>
      <groupId>org.mortbay.jetty</groupId>
      <artifactId>jetty-j2se6</artifactId>
    </exclusion>
  </exclusions>
</dependency>

但请记住，restfuse 1.0.0可能不适用于Jetty 9.如果是这样，你会想要追逐已为Jetty 9更新的更新版本的restfuse。

Answer 3

我在9.2.3修正了这个问题。请参阅错误报告https://bugs.eclipse.org/bugs/show_bug.cgi?id=438500

Answer 4

我收到此错误，因为目录“target / classes”不存在。解决这个问题的一种快速方法是简单地创建一个src / main / java文件夹，然后在那里创建任何类（甚至是一个空类）。

Answer 5

我使用eclipse Jetty插件时遇到了类似的问题。通过添加适当的依赖项解决了它。有关详细信息，请访问 - http://eclipse-jetty.github.io/faq.html

Answer 6

我遇到了同样的问题，并且我使用的是码头版本9.4.12.v20180830 之后，我将版本更改为9.4.12.RC2，一切正常

Jetty在关机时抛出NoClassDefFoundError：org / eclipse / jetty / util / FutureCallback
