In the built jar, the mcmod.info is wrong. It seems variables are not being applied. This only happens on 0.6.1 and not on 0.6.0-PRE-RELEASE-3. This makes the Prism Launcher unable to show the mod name and version. It also makes the mod menu show a @name@ mod

0.6.1:

[
  {
    "modid": "${modid}",
    "name": "${name}",
    "description": "",
    "version": "${version}",
    "mcversion": "${mcversion}",
    "url": "",
    "updateUrl": "",
    "authorList": [
      "Mohron"
    ],
    "credits": "",
    "logoFile": "",
    "screenshots": [],
    "dependencies": []
  }
]

0.6.0-PRE-RELEASE-3 :

[
  {
    "modid": "rockytweaks",
    "name": "RockyTweaks",
    "description": "",
    "version": "0.6.0-PRE-RELEASE-3",
    "mcversion": "1.12.2",
    "url": "",
    "updateUrl": "",
    "authorList": [
      "Mohron"
    ],
    "credits": "",
    "logoFile": "",
    "screenshots": [],
    "dependencies": []
  }
]

I will mention that this problem can be fixed by updating to a newer mod template, Cleanroom TemplateDevEnv

Is there a particular reason that you aren't using a prebuilt version of the mod? They're available via CurseForge. I don't have any plans to release new versions, so I don't intend on updating the project.

I'm talking about the prebuilt one, the mcmod.info inside the jar is broken
