Eclipse报告JSP文件中的语法错误，但应用程序可以正常工作

问题描述

限时删除！！

我正在检查一个JAVA项目的代码库，我发现Eclipse显示错误如下：

  c：if test =$ {not empty queryClauses&&（（activeRole eq'ROLE_ADMIN'&& &&&&&&&&Search.project.isPublic（））或（not querySearch.project.isPublic（））}}> 
< div class =control-btns> 
< input class =btn btn-primarytype =buttonid =updateQueryvalue =< spring：message code =query.updateQuery/>/> 
< input class =btn btn-primarytype =buttonid =deleteQueryvalue =< spring：message code =query.deleteQuery/>/> 
< / div> 
< / c：if> 
  

以下位置显示错误：

  querySearch.project.isPublic（）
  

错误是：

$ b

 在此行找到多个注释：
  -  EL语法错误
  - 遇到（ （在第1行
第87列
期待其中之一：
。... 
>... 
 
<... 
 ... 
  

这是由一位离开公司的同事写的，所以我不能问他，他确信这是可以的，但是我对Java项目中出现错误感到不舒服。

从搜索我发现以下注释：：

这是否同样的原因？有没有办法（通过更改项目代码或Eclipse设置）？将Eclipse更新以重新识别语法？

解决方案

似乎是一个长期的Eclipse验证错误：

截止撰写（在提出此SO问题后2年），仍然似乎没有已正确修复。

另请参阅中的评论。

I am inspecting codebase of one JAVA project, and I found that Eclipse shows error at the following lines:

<c:if test="${not empty queryClauses && ((activeRole eq 'ROLE_ADMIN' && querySearch.project.isPublic()) or (not querySearch.project.isPublic()))}">
    <div class="control-btns">
        <input class="btn btn-primary" type="button" id="updateQuery" value="<spring:message code="query.updateQuery" />"/>
        <input class="btn btn-primary" type="button" id="deleteQuery" value="<spring:message code="query.deleteQuery" />"/>
    </div>
</c:if>

Error is being showed at the following place:

querySearch.project.isPublic()

Error is:

Multiple annotations found at this line:
    - EL Syntax Error
    - Encountered " "(" "( "" at line 1,
     column 87.
Was expecting one of:
    "." ...
    ">" ...
    "gt" ...
    "<" ...
    ...

It was written by a co-worker, who has left the company, so I cannot ask Him about it. He assured that it is OK, but I feel bad about seeing an error in Java project.

From searching I found the following comment: https://stackoverflow.com/a/18417643/508654:

Is this the same reason? Is there a work-around (by changing project code or Eclipse settings)? Will Eclipse be updated to reckognize the syntax?

解决方案

Seems to be a longstanding Eclipse validation bug:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=352491

As of writing (2 years after this SO question was raised), it still doesn't appear to have been properly fixed.

Also see the comments in this similar question.
