reobfJar failed at patchReobfMappings

[Marco N.]

The reobfJar task fails with paperweight 1.1.9-SNAPSHOT

* What went wrong:
A problem was found with the configuration of task ':Fork-Tuinity-Server:patchReobfMappings' (type 'PatchMappings').
  - Type 'io.papermc.paperweight.tasks.PatchMappings' property 'patch' specifies file '...\ForkTuinity1.17\.gradle\CACHE_PATH\paperweight\upstreams\paper\build-data\reobf-mappings-patch.tiny' which doesn't exist.
    
    Reason: An input file was expected to be present but it doesn't exist.
    
    Possible solutions:
      1. Make sure the file exists before the task is called.
      2. Make sure that the task which produces the file is declared as an input.
    
    Please refer to https://docs.gradle.org/7.1/userguide/validation_problems.html#input_file_does_not_exist for more details about this problem.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

[Jason Penilla]

Not a paperweight issue. This is due to Tuinity's patch to workaround #45.

As far as an immediate solution for your fork, either
A) Revert the aforementioned workaround patch and live with #45 until it's properly fixed in paperweight
B) Fix/modify the workaround yourself, rootProject.layout.cache.resolve("paperweight/upstreams/paper/build-data/reobf-mappings-patch.tiny") needs to be changed to point to where this file actually is in your setup
