neo4j:install does not work on windows

Stack trace for the failure:

C:\blog>rake neo4j:install --trace

The install command is being called with a args[:edition] parameter in neo4j_server.rake, while the windows_server_manager version of install method does not take any parameters.

I ran into this bug trying to set up our project (https://github.com/pariyatti/kosa) for a volunteer designer, who is using Windows at the moment. It would be vastly preferable to use the Rake tasks to set up, configure, and manage Neo4j... they've been a godsend on Linux.

Unfortunately, I don't have a Windows machine to test this with right now. Remote pairing, we did fix the wrong number of arguments issue, which was trivial. It's easy to pass the edition_string as a param to the call to super here:

neo4j-rake_tasks/lib/neo4j/rake_tasks/windows_server_manager.rb

Lines 15 to 16 in b79b7c0

	def install
	super

After that, we had to change this line:

neo4j-rake_tasks/lib/neo4j/rake_tasks/server_manager.rb

Line 23 in b79b7c0

FileUtils.rm archive_path

to: FileUtils.rm archive_path, force: true

...though I don't think that's the right solution. This got us past that point, but it then seems like the jar isn't being downloaded at all, since in this line:

neo4j-rake_tasks/lib/neo4j/rake_tasks/server_manager.rb

Line 285 in b79b7c0

kernel_jar_path = Dir.glob(@path.join('lib/neo4j-kernel-*.jar'))[0]

Dir.glob(@path.join('lib/neo4j-kernel-*.jar')) is returning [] (empty array) and that file doesn't seem to exist at db/neo4j/development.

I'm on the side of a mountain with a mobile phone for internet so remote pair programming was too painful to actually bring this thing to a conclusion... but I think it's quite doable, and it would make the lives of your Windows users a thousand times better. 😸
