Are you sure you have permissions to log to this directory ?

I’m far from a windows expert but this is what is the first thought I had when I saw the error.

Hi,

 I have got the same warning, when I run 2nd command such as "vertx run ...".

 This is a log file locker, seems that we can not write to a same log file with more than one program.

 I can clean the warning when I stop 1st command.

yours,

David Zhang

Not sure how the implementation of jul handles that, but I would assume that it should be able to write to the same logfile from more than one program.
If this is exclusively locked, a solution would be to set a unique log file for each invocation or turning the file log off by putting logging.properties into $VERTX_HOME/conf or into src/main/platform_lib.

(When I run a test running a verticle twice that prints a message every second, I end up with 2 vertx.log files, one for each running instance.)
