Minecraft Forums

I recently had the issue of putting together a modded client and it not showing up in the Minecraft launcher
After a few Google searches and some read threads I found something...

I lied, I got very... unsatisfactory answers.

After some exploration of files I came up with a solution.

Grab Notepad++ and use it to open your JSON file.

You can use the regular Notepad or standard text editing program that came with your OS but I prefer to use Notepad++ and it has helped me in other situations. I recommend getting it either way.

The beginning should look like this:

{
"id": "name",
"time": "XXXX-XX-XXXXX:XX:XX-XX:XX",
"releaseTime": "XXXX-XX-XXXXX:XX:XX-XX:XX",
"type": "release",
"minecraftArguments": "--username ${auth_player_name} --version ${version_name} --gameDir ${game_directory} --assetsDir ${game_assets} --uuid ${auth_uuid} --accessToken ${auth_access_token}",
"libraries": [
{

The "id" for this client is "name" but my folder and files are "Name"

So within the folder "Name" I have "Name.jar" and "Name.json"
The client's id is "name"

To get the client to work I changed the "id" to "Name"

Now within my "Name" folder I have "Name.jar" and "Name.json"
With the client's id changed to "Name"

{
"id": "Name",
"time": "XXXX-XX-XXXXX:XX:XX-XX:XX",
"releaseTime": "XXXX-XX-XXXXX:XX:XX-XX:XX",
"type": "release",
"minecraftArguments": "--username ${auth_player_name} --version ${version_name} --gameDir ${game_directory} --assetsDir ${game_assets} --uuid ${auth_uuid} --accessToken ${auth_access_token}",
"libraries": [
{

After changing the "id" I was able to select my client in the launcher.

I really hope this helps at least some people.
