From what I understand from this : https://bugs.eclipse.org/bugs/show_bug.cgi?id=561415, the source tab editor is configurable.

I have found no documentation on how to configure it.

Right now, it defaults to eclipse "stuctured text editor" which lacks decent XML support. I have installed WTP xml editor plugin

How can I configure m2e to use it?

CodePudding user response：

Not possible as of now per @howlger comment. XML editor is definately broken for the moment.
