1.8.9-natives missing

[SylveonBottle]

I'm attempting to follow the tutorial found here, but when I get to 3:29, it says to add 1.8.9-natives and the folder isn't there.

I'm unsure if it's related, but I'm getting this error when attempting to run setup.bat:

Yes, the first step fails at copying the Twitch library, and that step exits early, causing the source and natives to not be present for the other steps (such as fixing the source).

I'm pretty sure that the natives and libraries are copied from your .minecraft, so try to launch a forge install from the Official Minecraft Launcher so that it can check all the natives and download those missing.

[SylveonBottle]

Forge "grabbed 13 libraries" upon installation, and after first launch the project worked as intended.

I kindly ask that you remove the "invalid" tag, as it may draw those seeking a similar solution away from this thread as a proper fix.

The reason why I put the invalid tag is because there's nothing wrong with the repo itself. It's actually a very common action that needs to be done when installing a different version, for example, Forge (because client makers assume you already have natives, libraries, etc which helps to ship a single .jar. Also, I don't know why I asked you to run Forge 1.8.9 instead of just Vanilla 1.8.9 because this does not have forge stuff.

I had already ran 1.8.9 prior and it didn't work, after installing forge it did work.
I'm not quite sure how this logic works at all.

Well, the thing is that when you run a version in the MC Launcher, it will check hashes of libraries/natives and redownload those missing/wrong. But the thing missing was Twitch which should be in the Vanilla 1.8.9 version...

well how about this, is this caused by mcp decompiler or ?

Jesus christ. Ummm, to be honest I have no clue. Try to restart completely from step one and delete the cloned repo. This is the first time such an issue has been reported and the code to 1.8.9 has not been changed since MCP made this. If this is the only issue you can correct it.

[dxxxxy]

I'll check later today to make sure I also don't have this apocalypse.

Issue #4 was caused by installing and launching Minecraft, then creating a new profile by 1.8.9 and launching it only a single time.

For some reason, after closing Minecraft and re-launching the launcher, an update was presented in which further files were downloaded. Despite Minecraft 1.8.9 launching successfully previously, mcp1.8.9op does not work unless you re-launch the Minecraft Launcher and let it update.

This shouldn't be an issue for users unless they use an alternative launcher (such as prism-launcher), and then install the vanilla launcher for the sole purpose of using it for mcp1.8.9op.
