Baritone: Could not get resource

[Bendito999]

When I try to 'setupDecompWorkspace', in the output log I get.
Could not get resource 'https://files.minecraftforge.net/maven/de/oceanlabs/mcp/mcp/1.12.2/mcp-1.12.2.pom'.

as this file does not exist. I'm having trouble finding it anywhere on the internet, do you have an alternative link? (or google drive of it maybe). Thank you.

[leijurv]

thats weird, can you post the full gradle log?

[leijurv]

ok i literally have no idea what this means lmao

[Bendito999]

lol, would you be willing to do a filesearch in your project directory and see if you have a mcp-1.12.2.pom in there, i'm wondering if it will just start working for me if I put that where it wants it. thank you leijurv.

Basically I'm just trying to get the dev environment built like the instructions say but am having trouble with the missing file when doing "Run the Gradle tasks setupDecompWorkspace then genIntellijRuns"

Basically I'm convinced that there was a file https://files.minecraftforge.net/maven/de/oceanlabs/mcp/mcp/1.12.2/mcp-1.12.2.pom
that existed once but no longer exists for some reason, maybe it is still cached in your directory tho...

Thank you for all your hardwork basically this project's existence reignited my love for block game.

want it?

It will probably still break. You probably have an outdated java version that does not trust lets-encrypt.

Forge's SSL certificates aren't supported by older versions of Java 1.8. Try installing the latest version available, then uninstall your old version. Specifically, anything older than Java 1.8.0_101 will not support Let's Encrypt certificates.

[Bendito999]

OMG that works, i'm rarted had old java 8_92 sneaking around somewhere even though I had specified 212 to be used by the IDE.
Thank you guys!
