# -Declipse.application=org.eclipse.jdt.ls.core.id1

# -Dosgi.sharedConfiguration.area.readOnly=true

|
|
# -Dlog.level:
|
|
# Log level.
|
|
# This can be overidden by setting JAVA_OPTS.
|
|
#
|
|
# The caller must specify the following:
|
|
#
|
|
# -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.
