primefaces扩展代码镜像无法正常工作。已加载primefaces 6.1及其支持的jar。commons-lang3-3.1，gson-2.2.4，primefaces-extensions-6.1.0
primefaces-extensions-6.1.0-没有资源.primefaces.extensions.codemirror并出现以下错误
WARNING [org.primefaces.util.ResourceUtils] (default task-58) Resource not
found, ignore it. Name: codemirror/codemirror.js, Library: primefaces-
extensions
。我手动添加了这些CSS和JS。现在completemethod不会触发，并在浏览器中出现以下异常。
Uncaught SyntaxError: Unexpected token <

使用的jar文件链接：
要使用codemirror扩展名，除了要在项目中包含库外，还必须在xhtml的顶部包含xmlns:pe="http://primefaces.org/ui/extensions"
