Things you'll need;
Lost-Isle Files
Gradle
Eclipse
First, make sure you have the files above, start by opening the Src and Client in Eclipse.
Next, in the files you'll want to install MongoDB, aswell as make a new folder in your C drive named "Data" without quotes.
Inside the "Data" folder, create a new folder named "db" without quotes.
Now, find your Environmental Variables and edit PATH with this: "C:\Program Files\MongoDB\Server\3.2\bin;"
Good, now next open up the Gradle link, and click and drag the 'Install' button onto Eclipse and let it install, after it's done it'll need to restart Eclipse, select yes.
Next, right click the Source folder, go to Configure>Add Gradle Nature
Now you should have like 9 errors, don't worry about them. I'll post the fix once I get off work.
Run the server first, wait until the console says ready, then run the client.
If this helped you, leave a 'like' if ya want.
