j'ai trouvé d'où venait le pb
J'avais commencé par lui indiquer le chemin exact de mon JDK mais ce n'était pas ça
ensuite j'ai commenté la partie Mac et là ça marche :-)
# ${HOME} will be replaced by user home directory according to platform
default_userdir="${HOME}/.${APPNAME}/trunk"
default_mac_userdir="${HOME}/Library/Application Support/${APPNAME}/trunk"
# options used by the launcher by default, can be overridden by explicit
# command line switches
# for development purposes you may wish to append: -J-Dnetbeans.logger.console=true -J-ea
default_options="--branding ancestris -J-Xms96m -J-Xmx768m --laf Nimbus"
# The following line doesn't work with Linux Operating System (change 1 of 2 - see below)
#default_options="--branding ancestris -J-Xms96m -J-Xmx768m -J-Dplugin.manager.install.global=true"
# default location of JDK/JRE, can be overridden by using --jdkhome <dir> switch
#jdkhome="c:\Program Files\Java\jdk1.8.0_144"
# clusters' paths separated by path.separator (semicolon on Windows, colon on Unices)
#extra_clusters=
# The following line doesn't work with Linux Operating System (change 2 of 2 - see above)
#extra_clusters=${progdir}/../extra
## Special APPNAME for Mac
#case "`uname`" in
# Darwin*)
# default_options="${default_options} -J-Xdock:name=\"Ancestris\""
# ;;
#esac
