Re: [m2e-dev] m2e 0.13 - can't import anything anymore :(

[Max Rydahl Andersen <max.andersen@xxxxxxxxxx>]

Hi,

Saw the git commits about allowing install and took the latest update and now things looks much better - at least I can import now most of the times ;)

The only thing annoying is that it puts error markers on the project which hides where there is *actual* serious compile/build problems.

What is the magic to put in pom.xml's to get it to ignore it ?

And would you guys accept a patch for controlling the severity of this error ? (I couldn't find a way to control it currently)
