Hello,
I'm using Emacs 28.1 on Windows 64 bits.
I'm compiling Java sources using a compilation command which launches
javac through a project management tool. That works fine but when
there are compilation errors they appear as follows in the compilation
buffer:
C:\Users\..\file.java:307: error: ';' expected
The 2 spaces before the file name are taken into account in the name,
and the attempt to open file with emacs fails.
I think I need to adapt compilation-error-regexp-alist, but it's not
obvious how to do it. Any suggestion would be welcome.

I modified compilation-error-regexp-alist as follows ant it works:
(add-to-list 'compilation-error-regexp-alist
'("^[[:blank:]]+\\([[:alnum:]/\\].*\\):\\([0-9]+\\):[[:blank:]]+\\(?:error\\|\\(warning\\)\\|\\(info\\)\\)"
1 2 nil (3 . 4) 1))
(i am not sure there are info messages from javac compiler)
But I have a couple of questions. IIUW my problem comes from the fact
there is at least one regexp in compilation-error-regexp-alist that
matches the error line without removing spaces at beginning of file
name. But there's no mean to identify that regexp. Regexp definitions
are set in compilation-error-regexp-alist-alist and they don't use a
uniform way of coding with makes them difficult to read.
Should'nt the definition of the list change according to the
programming modes used?
