Mark Struberg commented on MEECROWAVE-130:
------------------------------------------
[https://github.com/apache/meecrowave/blob/trunk/meecrowave-core/src/main/java/org/apache/meecrowave/Meecrowave.java#L467]
we currently *always* create the whole directory structure in MEECROWAVE_BASE:
lib, logs, temp, work, webapps
Do we really use any of those directories?
* lib is *not* required in MEECROWAVE_BASE. Only in MEECROWAVE_HOME - if any.
Because if you use meecrowave-runner.jar then we do not require lib, right? And
in any other case it gets created by the distribution.
* logs: This is a bit special. It is only required if there is no special
MEECROWAVE_OUT set _and_ if people stick with the default logging. In case they
overwrite it to use ConsoleLogger or another location (/var/log/..) then this
directory is unused.
* temp: is this really used in Meecrowave? It should only get created if
MEECROWAVE_TMPDIR is not explicitly set to some other directory.
* work: is this also really used? I think this is only used in Tomcat to store
stuff like the compiled JSP files. Since we don't ship JSP at all we probably
could leave this off?
* webapps: hmmm only needed if we deploy WAR files, right? If we use
meecrowave:bundle with just a jar, then this is not required imo. But this
directory is probably a hard nut.

> In my project I have the MEECROWAVE_OUT and MEECROWAVE_BASE is set to
> separated places.
> MEECROWAVE_BASE is in /opt/myapp
> and
> MEECROWAVE_OUT is in /var/log/myapp.log
> Since mw-1.2.2 I now get the following Exception:
> {noformat}
> Exception in thread "main" java.lang.IllegalStateException: /opt/myapp/logs
> can't be created
> at org.apache.meecrowave.io.IO.mkdirs(IO.java:89)
