I have pylint installed (works fine on the command line) and set up within Pydev in Eclipse.
Pylint is being triggered OK when I edit files, and is outputting to the Ecl
I was having the same problem, and it turned out to be my pylint configuration file (~/.pylintrc by default). Be sure the output-format field is correct. It is under the [REPORTS] section, and the line should be:
output-format=text
If you've ever used pylint with another application (I do with emacs), it might say output-format=parseable.
