我正在通过 Eclipse Jetty Maven 插件 (9.1.0.M0) 使用嵌入式 Jetty。
我的 pom.xml 中有以下插件配置:
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>${version.jetty}</version>
<configuration>
<scanIntervalSeconds>10</scanIntervalSeconds>
<daemon>true</daemon>
<webApp>
<contextPath>/</contextPath>
<descriptor>${basedir}/src/test/webapp/WEB-INF/web.xml</descriptor>
</webApp>
<httpConnector>
<port>48080</port>
</httpConnector>
<stopPort>19081</stopPort>
<stopKey>53AS9DS1FD8E3WEFEW9GR1ER8G2ER0WE31</stopKey>
</configuration>
<executions>
<execution>
<id>jetty-start</id>
<phase>test-compile</phase>
<goals>
<goal>run</goal>
</goals>
</execution>
<execution>
<id>jetty-stop</id>
<phase>test</phase>
<goals>
<goal>stop</goal>
</goals>
</execution>
</executions>
</plugin>
当 Jetty 关闭时，我不断收到以下异常:

我试过添加
jetty-util作为插件的依赖项，(还有——项目)。这没有帮助，它让我发疯。虽然构建确实通过了，但当 Jetty 在我的 Maven 构建结束时关闭时，我真的无法忍受看到这些错误。请指教!提前谢谢了!
最佳答案
我建议您使用发行版，例如9.0.5.v20130815 , 而不是你现在使用的里程碑(仍在开发中) 9.1.0.M0
