我也收到消息：
Invalid input url:platform:/plugin/org.springframework.ide.eclipse.ui/icons/full/obj16/spring_perspective.gif
同时具有相同的堆栈跟踪。
我尝试使用“帮助/检查更新”来更新组件，但是我还收到以下消息：
"the operation cannot be completed." trying to update "Eclipse Help System" and "Eclipse Platform" with the reason ... requires "osgl.service: (objectClass=prg.osgi.service.event.EventAdmin)"
建议？
答案 0 :(得分：0)
我发现了问题。当您手动删除Maven存储库的某些部分时，会发生这种情况。即
rm -rf MVN_REPO/*
然后尝试重建。这将删除.factorypath所需的jar。即使您有Maven来重建项目，也无法找到为当前软件包更新.factorypath或加载.factorypath中指定的适当软件包的方法。
的确，我注意到，如果您错误地允许非RELEASE软件包填充您的.factorypath，那么您可能会无法下载所需的软件包版本，因为这些临时软件包不在维护库中无限期地。
