grails 4 从另一个标签库调用命名空间标签库

Question

如何在 grails 4 中访问与另一个标签库具有不同命名空间的标签库？我好像不能打电话。

这是一个例子

 class MyLibTagLib{

  static namespace="myLib"

  def fancy={attrs->
      ....
  }
}

import app.lib.MyLibTagLib
class CallerTagLib{

  //in the default 'g' namespace

  //def myLib //injection fails

  def fancyText={attrs->
      //fails
      out << myLib.fancy(attrs)
      //also fails
      grailsApplication.mainContext.getBean('app.lib.MyLibTagLib')
  }
}
