Error on bob aar build

[LerDelijan]

Question

Hello,
My goal is to build an aar using bob. After I've executed create script:
npx @react-native-community/bob create react-native-awesome-module
I have added aar to targets in package.json:

"@react-native-community/bob": {
    "source": "src",
    "output": "lib",
    "targets": [
      ["aar", { "reverseJetify": true }],
      "commonjs",
      "module",
      "typescript"
    ]
  }

The error I get is as follows:

D:\react-native-awesome-module>bob build
ℹ Building target aar
ℹ Cleaning up previous build at lib\aar
ℹ Assembling Android project in android with gradle
bob.js build

build files for publishing

Options:
  --help     Show help                                                 [boolean]
  --version  Show version number                                       [boolean]

Error: The gradlew script doesn't seem to present in android. Make sure you have added it by running gradle wrapper in that directory.

Both gradlew and gradlew.bat files do present in android directory.

Should I add some extra configuration to build an aar or I have missed something in docs?

Thanks in advance!

cc @matt-oakes any ideas?

I think this is the issue here. On windows, gradleWrapper gets resolved to ./gradlew./gradlew.bat which doesn't work. I changed that line to the following and it ran without problems:

  const gradleWrapper = ((0, _os.platform)() === 'win32' ? 'gradlew.bat' : './gradlew');

@chadmorrow Thank you for finding the solution!
Perhaps you would like to make a PR solving this issue with the fix you found?

[stacygrace]

Sure! I can work on that later today

I ran into the same problem. I'll try it your way. @chadmorrow

@chadmorrow how to implement const gradleWrapper = ((0, _os.platform)() === 'win32' ? 'gradlew.bat' : './gradlew');
