Logback configuration via jvm argument

Question

How can we load logback.xml via jvm argument if this is not present in project classpath?

I'm using

 -Dlogback.configuration=file:C:\logbacs\logback.xml

but this is not working.

I found the solution

-Dlogging.config="C:\logbacs\logback.xml"

is working fine for me.

Updated because the previous answer was obsolete

...where do we specify the location of file, is it in VM arguments in RUN configuration of my eclipse project OR is it a configuration file in tomcat ? – MKod May 20 '16 at 18:32

If you're not using SpringBoot the above won't work.

I'm using the ch.qos.logback.logback-classic library, and in this case the solution is

-Dlogback.configurationFile=file:/app/logback.xml

I've found this property in ch.qos.logback.classic.util.ContextInitializer:

final public static String CONFIG_FILE_PROPERTY = "logback.configurationFile"

This definitely not correct anymore in recent versions of spring boot. It's `-Dlogging.config`, see answer by @Fre_d – jaw Aug 14 '18 at 12:08

like I've said, I've used -Dlogback.configurationFile property because I wasn't using spring boot. If you use SB, then you should use -Dlogging.config – Rudi Aug 15 '18 at 07:32
Not necessary to explore Logback's source code, using this property is explained here : http://logback.qos.ch/manual/configuration.html#configFileProperty – jdarthenay Jan 06 '21 at 13:44
For Windows -Dlogback.configurationFile=file:///C:/logbacs/logback.xml – JustinKSU Jun 07 '21 at 21:15

The original answer to this question doesn't appear to be working anymore as it produces this warning instead:

o.s.b.l.logback.LogbackLoggingSystem     : Ignoring 'logback.configurationFile' system property. Please use 'logging.config' instead.

Therefore, you would want to use something like this:

-Dlogging.config="C:\logbacs\logback.xml"

For me it works only with this property:

-Dconfig.dir= "YOUR PATH TO CONFIG FILE"
