本文介绍了解决Eclipse在尝试将项目Java版本更改为1.8时出现的错误问题。通过删除特定的.classpath文件中的某一行内容，可以顺利进行版本设置。

在使用eclipse导入一个新的项目时，项目-->鼠标右键-->Properties 弹出框中修改Project Facets为1.8时，eclipse报错，错误信息如下：


Failed while changing version of Java to 1.8.
Project facet jst.web.jstl has not been defined.

网上搜索后找到了一种解决方法，如下：


找到项目目录中的.classpath文件夹


使用notepad++工具打开，如下：



将红框中的一行删除就可以了


<attribute name="owner.project.facets" value="jst.web.jstl"/>

重新修改Project Facets 中的java，发现成功了，项目中的红叉没有了

在移植eclipse项目时，如果遇到 “Project facet Java version 1.7 is not supported.” 项目中的jdk1.7不支持。说明项目是其他版本jdk编译的，在eclipse里运行时会报版本不支持。 解决办法: 法1，选中项目 Properties , 选择 Project Facets,右击选择 Java , Chan

可能忘了在使用Class的文件中包含class.h，也就是忘了加头文件。 可能Class名称写错了，或者头文件名写错了，少写、大小写。 忘记修改保护#define的名称。 命名空间是否有错误，没有在命名空间内或者命名空间错误。 可能正在使用模板，而不希望两阶段查找按其方式工作。 可能已经使Class成为仅在包含Class.h之后才定义的宏，在这种情况下，看到的Class被宏预处理器替换为其他宏。 可能已经在问题文件.h以外的头文件中定义了问题类，然后问题类.h实际上定义了其他内容。 ...
