the background of my question is that I'd like emacs to be able of jumping
to the source that caused the error. That has stopped working for me since
switching to Maven.
However, I've now managed to restorE that to a reasonable extent (I hope)
by adding an additional regular expression to the list that emacs uses
for parsing compilation errors by adding
(setq compilation-error-regexp-alist (cons '("^\\(\\[WARNING\\]
\\)?\\(/[^:]+\\):\\[\\([0-9]+\\),\\([0-9]+\\)\\]" 2 3 4)
compilation-error-regexp-alist))
to my ~/.emacs startup file.
The maven compilation error messages don't contain any constant text that
one could easily use for matching with a regular expression, my regexp
above just relies on error messages starting with a forward slash (as part
of the absolute path to the source file) and that the line number is
separated from the file name by ":[". So as a thought, perhaps a future
version of maven could change the format to contain a fixed, regexp-friendly
string -- or perhaps error message formats could become configurable via
pom settings.
