[MC] - Version (1.16.*)

[Wilson08]

Hi I'm following the steps in the readme and I was successful with versions <= 1.15.2. 👍 😄
Versions above (1.16. *) are not working. 😢
I tried to use the command heroku ps: exec and look through the directories for any log but the log folder is not generated when I run with mc version (1.16.1).

• This image says that the jar file is corrupted (the link looks ok to me in the code)
  
• I found this error a little strange, see how I did it to work:

heroku ps:exec
rm minecraft.jar
curl -o minecraft.jar -s -L https://launcher.mojang.com/v1/objects/a412fd69db1f81db3f511c1463fd304675244077/server.jar
screen -L -h 2048 -dmS minecraft java -Xmx384m -Xms384M -jar minecraft.jar nogui
screen -r

The Heroku buildpack file is outdated, causing it to use 1.15.2 as the default - this is the same problem which caused #52.
For some reason, the fall through call to minecraft_url="https://s3.amazonaws.com/Minecraft.Download/versions/${minecraft_version}/minecraft_server.${minecraft_version}.jar" is returning an access denied error, so that the contents of minecraft.jar are as follows:

<?xml version="1.0" encoding="UTF-8"?>
<Error><Code>AccessDenied</Code><Message>Access Denied</Message><RequestId>4Y8P6PAG4GAGBM1P</RequestId><HostId>V3hEgTGTBI3U8iJ0WoF1/9MIIU0c542jP4mBRDIahmVQVX0MiFuPuJr/YSCG3p/iF3pOWnNTsUo=</HostId></Error>

I'm not sure why access would be denied as it seems that URLs like https://s3.amazonaws.com/Minecraft.Download/versions/1.6.3/minecraft_server.1.6.3.jar are publicly available without any kind of authentication, and the request just looks like curl -o minecraft.jar -s -L $minecraft_url.

Looks like this S3 bucket stopped being populated with server versions after 1.13.1.

PASS: https://s3.amazonaws.com/Minecraft.Download/versions/1.13.1/minecraft_server.1.13.1.jar
FAIL: https://s3.amazonaws.com/Minecraft.Download/versions/1.13.2/minecraft_server.1.13.2.jar

Strangely, this is accounted for in /bin/compile on line 68 elif echo "$minecraft_version" | grep -q '^1\.16.*$'; then but as you can see, it matches ALL minor versions of the 1.16 release to the 1.16.1 launcher.mojang Object UUID. minecraft_uuid="${MINECRAFT_UUID:="a412fd69db1f81db3f511c1463fd304675244077"}"

So either, some research needs to identify specific version UUIDs, or an alternate download source needs to be added.
