Cannot change version of project facet Dynamic Web Module to 2.5
找到工程项目的硬盘目录,打开项目下的 .setting文件夹,如下图:
找到 .setting文件夹内的org.eclipse.wst.common.project.facet.core.xml文件,文件格式大致如下:
<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
<runtime name="Apache Tomcat v5.5"/>
<fixed facet="jst.web"/>
<fixed facet="jst.java"/>
<installed facet="jst.java" version="5.0"/>
<installed facet="jst.web" version="2.3"/>
<installed facet="wst.jsdt.web" version="1.0"/>
</faceted-project>
直接手动修改jst.web对应的version即可(2.3 -> 2.5)。最后重启tomcatX就可以正常使用了。
如果eclipse的图标中还报错(打红叉),如果项目是Eclipse项目,则可以右击eclipse,选中Maven-》Update Maven Project,这样就可以成功的讲jst.web的修改应用到eclipse中了。如果不是Maven的Project,则可以关掉改Project,重新打开,这样也可以将Project的变化重新应用到eclipse中
