Can not find the tag library descriptor for "http://java.sun.com/jsp/jstl/core" pager.tag

坑王指数 **

评论：jstl版本问题，对于我这纯后端来说有点小意外，前端同学偷偷的乐吧！

Errors occurred during the build Errors running builder 'CDI (Contexts and Dependency Injection) Builder' on project 'demo.server' Unknown tag! pos=40 poolCount = 47

评论：CDI不是重点，Unknown tag! pos=40 poolCount = 47 才是，我说的对么？

Missing artifact com.***.**:jar:0.0.1

坑王指数 ****

评论：同在一个POM组怎么就不能识别呢？？？

Expected value at 1:0 config.json /demo/src/main/webapp/js/scripts/ueditor/jsp line 1 JSON Problem

Description Resource Path Location Type

ActionEnter cannot be resolved to a type controller.jsp /push/rc/main/webapp/js/scripts/ueditor/jsp line 12 JSP Problem
坑王指数 **

评论：不识别ActionEnter 类，这是百度的文件工具，maven看到有 mini 但是加上之后不能用，于是用了git上的一个版本拷贝ueditor-1.1.2.jar到工程里再添加classpath即可

Description Resource Path Location Type

Expected name at 2:0 config.json /push/src/main/webapp/js/ueditor/jsp line 2 JSON Problem

坑王指数 ****

评论：版本问题不识别注释块标记 /* */ 我调试了几次没弄好最后把注释去掉才没报错

Description Resource Path Location Type

The entity name must immediately follow the '&' in the entity reference. show.html /push/src/main/webapp/js/scripts/ueditor/dialogs/map line 26 XHTML Problem

坑王指数 ***

评论：&和amp;是等价的对js不熟，所以猜测仍是版本问题导致

评论：Window->Preferences->JBoss Tools->Maven Intagration-> Uncheck "CDI Facet" THEN Project Properties->CDI Settings->Uncheck "CDI Support" 问题解决！
