errorformat for Java junit output

Question

I am trying to get VIM to jump to the file listed in the error. So the following is the error.

|| 1) test01(ErrorTest0)
|| java.lang.NullPointerException
||  at Line.equals(Line.java:43)
||  at ErrorTest0.test01(ErrorTest0.java:22)

I tried the following errorformat set errorformat='%.%#\ at\ %.%#(%f:%l)' , but it does not work.

So all I want it to do is jump to the file Line.java line 43 when I click on it. Am I missing something in errorfomat?

First thing I notice is that you have quotes in there. When using set everything after the = symbol is set to the value.

Since errorformat has spaces and backslashes my preferred way to set it is with let and single-quoted strings, then string concatenation so I can break it up into more easily parsed lines.

let &errorformat =
    \  '%*[^"]"%f"%*\D%l: %m,'
    \. '"%f"%*\D%l: %m,'
    \. '%-G%f:%l: (Each undeclared identifier is reported only once,'
    \. etc.

So in your case it's a lot easier, let's just try it like this:

let &errorformat = '%.%# at %.%#(%f:%l)'

However you could get really fancy with multiline strings, using %E and its friends to collapse those error lines down into just the relevant info in your quickfix window but I still find that to be a bit fiddly.
