Etienne We just released version 3.5.38 of the Wrapper which adds a set of properties to change the group of the files created by the Wrapper. The group can be set globally for all files (with the wrapper.group property), or individually for each file (log file, pid file, anchor file, etc.). Please check the following page for details: https://wrapper.tanukisoftware.com/doc/english/prop-group.html This new version contains several other improvements which are listed in our release notes: https://wrapper.tanukisoftware.com/doc/english/release-notes.html It can be downloaded from the following link: https://wrapper.tanukisoftware.com/doc/english/download.jsp Best Regards, The Java Service Wrapper Team On Wed, Sep 12, 2018 at 9:33 PM Etienne Jouvin <lap...@gm...> wrote: > And finally. > > What I did, because I work on Linux plateform. > Log folder is /var/log/jenkins > > And I execute the following command > chmod g+s /var/log/jenkins > > > Regards > > Etienne Jouvin > > > Le mer. 12 sept. 2018 à 14:10, Etienne Jouvin <lap...@gm...> a > écrit : > >> Ok fine. >> >> I was "just" wondering and I have the answer. >> >> I will manage in other way. >> >> Regards >> >> Etienne >> >> >> Le mer. 12 sept. 2018 à 04:16, Maxime Andrighetto < >> max...@ta...> a écrit : >> >>> Etienne >>> >>> Sorry, I was mistaken.
