I get the following error when trying to run my mod. The processResources Gradle script doesn't seem to work.

Execution failed for task ':processResources'.

Some context: I originally made this mod in 1.17 and have updated it through every version since. This happened after the update to 1.20. Because my Gradle files where becoming outdated I opted to copy the gradle files from a newer project so they would be up to date. The "Load Gradle Changes" button works fine. It's just that this fails when I try to launch the game.

The gradle files I updated were:

• build.gradle
• gradle.properties
• mods.toml
• settings.gradle
• gradle-wrapper.jar (from the folder gradle\wrapper)
• gradle-wrapper.properties (from the folder gradle\wrapper)

 

EDIT:

Here are some file fragments from what I think could be relevant. I've removed comments for readability.

 build.gradle (partially):

def resourceTargets = ['META-INF/mods.toml', 'pack.mcmeta']
def replaceProperties = [
        minecraft_version: minecraft_version, minecraft_version_range: minecraft_version_range,
        forge_version: forge_version, forge_version_range: forge_version_range,
        loader_version_range: loader_version_range,
        mod_id: mod_id, mod_name: mod_name, mod_license: mod_license, mod_version: mod_version,
        mod_authors: mod_authors, mod_description: mod_description
]
processResources {
    inputs.properties replaceProperties
    replaceProperties.put 'project', project

    filesMatching(resourceTargets) {
        expand replaceProperties
    }
}

 

mods.toml:

modLoader="javafml"

loaderVersion="${loader_version_range}"

license="${mod_license}"

[[mods]]

modId="${mod_id}"

version="${mod_version}"

displayName="${mod_name}"

[[dependencies.unnamedmod]]
    modId="minecraft"
    mandatory=true
    versionRange="${minecraft_version_range}"
    ordering="NONE"
    side="BOTH"

 

properties.gradle:

org.gradle.jvmargs=-Xmx3G

That error says gradle is trying to copy your mods.toml, replacing properties as it does so.

One of the properties in your mods.toml is something like:

${file}

But you haven't defined what that value should be in your processResources task in the buid.gradle

unlike the other defined properties: https://github.com/MinecraftForge/MinecraftForge/blob/ab70bde1d648125acee073a93a25d4b8f08985c9/mdk/build.gradle#L153

which probably actually come from the gradle.properties?

 

Beyond that we can't help you. We have no psychic powers. You don't show the contents of any of your files.

You should put a simple project on github that reproduces your problem if you want further help.

I've added some contents of my files to the original post of what I think is relevant. Hopefully that could help solving the issue.

I solved it, but maybe not in the correct way. The problem was that I needed to add 

file: file

to the replaceProperties in build.gradle. I then added

file=examplefile

to gradle.properties. What would be a better value than "examplefile"? I don't really know what file it's looking for

I think you can try checking if the following text exists in your mods.toml comments:

• ${file.jarVersion}
• ${file}
• ${}
