Failed to transform file 'hermes-debug.aar' to match attributes {artifactType=android-manifest}

[Maskedman99]

I am trying to enable hermes in my app as per the instruction given in https://facebook.github.io/react-native/docs/hermes . After following the instructions, when I try to run my app I get the following error.

O.K. solved it by creating a new app and enabling hermes in that one and it worked, so I compared the build.gradle files of both and found out

               def hermesPath = "../../node_modules/hermes-engine/android/"; 

is used in if(enableHermes) instead "../../node_modules/hermesvm/android/" . Wondering why they didn't mention this in the getting started documents.

[dulinriley]

Yes this is probably related to us renaming our npm package from hermesvm to hermes-engine. It doesn't look the documentation specifically mentions hermesvm though, so maybe it was an update somewhere else that fixed it?

[inceabdullah]

The same error. After changing hermesvm to hermes-engine in build.gradl but right now just crash.

@inceabdullah I think the issue is here:

project.ext.react = [
    ...
    hermesCommand: "../../node_modules/hermesvm/%OS-BIN%/hermes",
    ...
]

Trying changing that path to "../../node_modules/hermes-engine/%OS-BIN%/hermes"

[bandojulio]

O.K. solved it by creating a new app and enabling hermes in that one and it worked, so I compared the build.gradle files of both and found out

               def hermesPath = "../../node_modules/hermes-engine/android/"; 

is used in if(enableHermes) instead "../../node_modules/hermesvm/android/" . Wondering why they didn't mention this in the getting started documents.

solved my issue! I had this problem when changed my project to monorepo.

[iJimmyWei]

Hermes renamed their binary from hermes to hermesc a while ago - https://github.com/facebook/react-native/commit/4305a291a9408ca65847994bbec42f1fbc97071d

You should make sure you change it accordingly too, like this:

project.ext.react = [
    ...
    hermesCommand: "../../node_modules/hermesvm/%OS-BIN%/hermesc", // notice the extra "C"
    ...
]

Thanks! this approach worked for me too, but replacing for:

    if (enableHermes) {
        //noinspection GradleDynamicVersion
        implementation("com.facebook.react:hermes-engine:+") { // From node_modules
            exclude group:'com.facebook.fbjni'

    } else {
