我正在运行Eclipse Mars 4.5.1。我安装了Tomcat 7和8。我安装了Java 7和8 JDK。
我已经导入了一个应该在Tomcat 8和Java 8上运行的项目。（我让它在另一台计算机上运行得很好，并将其拉到这台计算机+工作区，从另一个位置处理它。）
我创建了一个使用Apache Tomcat v8.0运行时环境的服务器配置，使用JRE jdk1.8.0_66（不工作空间默认JRE，以防万一） ，并将我的项目作为其唯一模块。
项目的构建路径库包括JRE System Library [JavaSE-1.8]和Apache Tomcat v8.0 [Apache Tomcat v8.0]，以及Maven依赖项。
该项目包含Dynamic Web Module 3.1，Java 1.8和Javascript 1.0方面。
项目启动并执行一些控制器代码，但是当它编译任何JSP时，我得到一系列异常，其中最有用的表示The type java.util.Map$Entry cannot be resolved.
我已经尝试将所有内容切换到Java 7（我的工作区的默认JRE），这没有任何区别。我尝试了各种更改，但我尝试过的任何内容都不允许加载java.util.Map。我做错了什么？
