在Eclipse SuperDevMode中启动GWT应用程序时出现org.eclipse.jetty.util.MultiException

问题描述

当我尝试在Eclipse中启动GWT应用程序时，我面临以下异常（与旧版Devmode和SuperDevmode相同）。我尝试使用最新的Eclipse版本（2020-06）和Eclipse Photon。
Eclipse嵌入式Jetty版本似乎是一个问题，但最新的Eclipse（2020-06）应该包含支持JEP-238多发布Jars的Jetty版本。

java Vesion 1.8

GWT版本2.8.2

有人知道我在做什么错吗？

解决方法

您在gwt中拥有的Jetty版本与JEP-238（MultiRelease）jar文件不兼容。

特别是这个...

从jar文件中扫描条目META-INF / versions / 9 / javax / xml / bind / ModuleUtil.class时出错：/ C：/ local / ws / new / web / internal / internal-war / target / webtest / WEB-INF / lib / jaxb-api-2.3.1.jar

您需要使用具有Jetty 9.4.9或更高版本的gwt来支持JEP-238 jar文件。
