# Fact: java_version

# Purpose: get full java version string

|
|
# Resolution:
|
|
# Tests for presence of java, returns nil if not present
|
|
# returns output of "java -version" and splits on '"'

# Caveats:

# none

# to indicate "no java available". Usually returning nil
|
|
# would mean that facter falls back to a lower priority
|
|
# resolution, which would then trigger MODULES-2637. To
|
|
# avoid that, we confine the "default" here to not run
|
|
# on those OS.
|
|
# Additionally, facter versions prior to 2.0.1 only support
|
|
# positive matches, so this needs to be done manually in setcode.
