'com.google.gwt.dev.shell.jetty.JettyLauncher.WebAppContextWithReload'类的对象不是'org.eclipse.jetty.webapp.WebAppContext'类型的对象

Question

当我试图在SuperDevMode中启动我的GWT项目时在的IntelliJ我收到以下错误：

2016-11-22 09:32:25,752 [main] INFO org.eclipse.jetty.server.Server - jetty-9.2.14.v20151106

我加入GWT-dev下的建议： Gwt 2.8-rc1 super dev mode is not working on IntelliJ IDEA 2016.2.5

运行的conf iguration VM选项：

-Xmx2048m -XX：MaxPermSize参数=1024米-Djava.naming.factory.initial = org.eclipse.jetty.jndi.InitialContextFactory

码头-web.xml配置：

<?xml version="1.0"?> 
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_3.dtd"> 
<Configure id="wac" class="org.eclipse.jetty.webapp.WebAppContext"> 
    <New id="configurationDataSource" class="org.eclipse.jetty.plus.jndi.Resource"> 

     <Arg>jdbc/configurationDataSource</Arg> 
     <Arg> 
      <New class="org.apache.commons.dbcp.BasicDataSource"> 
       <Set name="driverClassName">oracle.jdbc.OracleDriver</Set> 
       <Set name="url">xxx</Set> 
       <Set name="username">xxx</Set> 
       <Set name="password">xxx/Set> 
      </New> 
     </Arg> 
    </New> 
    <New id="configuration" class="org.eclipse.jetty.plus.jndi.EnvEntry"> 
     <Arg>configuration</Arg> 
     <Arg type="java.lang.String">classpath:META-INF/application-local.properties</Arg> 
     <Arg type="boolean">true</Arg> 
    </New> 
</Configure> 

我分析了mvn依赖关系：树。有没有包括额外的码头版本

路径GWT安装目录：

C：\用户\ xxx.m2 \库\ COM \谷歌\ GWT \ GWT-dev的\ 2.8.0

JDK版本：8

Answer 1

当我将IntelliJ IDEA从2016.2.5更新至2016.3时，问题消失。
