The following is done with NB Platform 11.3 and Java 11 on Kubuntu 20.04. While I was about to use the cache dir logic provided by the platform I ran into this problem.
My cache dir is in ${HOME}/.${APPNAME}/var/cache and not as expected, ${HOME}/.cache/${APPNAME} The app.conf contains default_userdir="${DEFAULT_USERDIR_ROOT}/dev" default_cachedir="${DEFAULT_CACHEDIR_ROOT}/dev" Did some echoing in the bin/appname and DEFAULT_CACHEDIR_ROOT was set ok, but not picked up by the application. When specifying --cachedir it gets picked up by the application. I created a simple testapp and this problem is there too. So I guess the question is, Is this related to my doing or the platform? /Patrik
