# The wrapper script will create a directory in the user's cache, copy in the config
# files since this dir can't be read-only, and by default use this as the runtime dir.
#
# The following options are required as per the upstream documentation:
#
# -Declipse.application=org.eclipse.jdt.ls.core.id1
# -Dosgi.bundles.defaultStartLevel=4
# -Declipse.product=org.eclipse.jdt.ls.core.product
# -noverify
# --add-modules=ALL-SYSTEM
# --add-opens java.base/java.util=ALL-UNNAMED
# --add-opens java.base/java.lang=ALL-UNNAMED
#
# Other options which the user may change:
#
# -Dlog.level:
# Log level.
# This can be overidden by setting JAVA_OPTS.
# -configuration:
# The application will read the configuration from this directory but also needs
# to be able to write here (hence mode 17777).
# This can be overidden by specifying -configuration to the wrapper.
# -data:
# The application stores runtime data here. We set this to <cache-dir>/$PWD
# so that projects don't collide with each other.
# This can be overidden by specifying -configuration to the wrapper.
#
# Java options, such as -Xms and Xmx can be specified by setting JAVA_OPTS.
