This plugin allows to upload a file to a Google Drive folder. Currently it does not support downloading of files and uploading to Team drives and the domain corpus, but you are welcome to show your interest in the corresponding issue or to provide a PR.

Obtaining credentials

1. Go to Google API Console and create a project.

2. Go to Credentials section of just created project.

3. Choose Create credentials → OAuth client id → Other. Copy the id and the secret.

You have to provide the values to an extension with name googleDrive inside the build script. You may do this anyway you like: get from an environment variable, system property if you’d like, or from a gradle.properties, which is the most convenient to me.

Usage

By default, the plugin applies a task named 'uploadToDrive' which expects an extension named googleDrive to be defined, like so:

plugins {
    id 'ru.kinca.google-drive-uploader' version '1.1.0'
}

googleDrive {
    // Missing folders will be created
    destinationFolderPath = 'test/upload'

    // Or you can specify a folder id
    destinationFolderId = '1abcedefg'

    // If not specified, simple file name is used
    destinationName = 'cute_picture.jpg'

    file = file('c:\\Users\\User\\Pictures\\kittens.jpg')

    // Default is true
    updateIfExists = false

    // Do not put those directly into the build file
    clientId  = '<YOUR CLIENT ID>'
    clientSecret = '<YOUR CLIENT SECRET>'

    // Location where Google Drive client's credentials will be stored. You may
    // want to have a separate dir for each project.
    // Default is `${user.home}/.credentials/google-drive-uploader`, i.e.
    // shared between all projects.
    credentialsDir = file('.gradle/google-drive-uploader/credentials/')
}

Note	If no permissions were set explicitly, the file will be publicly shared for reading.

Execute uploadToDrive task to perform the upload.

When updating an existing file, the specified permissions will be set, but existing ones would stay untouched.

Setting custom permissions

import com.google.api.services.drive.model.Permission

googleDrive {
    // Other properties configured...
    permissions = [new Permission()
                       .setType('user')
                       .setEmailAddress('example@gmail.com')
                       .setRole('writer')]
}

Uploading to another user’s Drive

Go to Shared with me tab, get the URL which will be like https://drive.google.com/drive/folders/sharedFolderId.

Or get a direct url to the folder https://drive.google.com/open?id=sharedFolderId.

googleDrive {
    // Other properties configured...

    destinationFolderId = 'sharedFolderId'
}

Note	You can specify either destinationFolderPath or destinationFolderId, not both.

Example

settings.gradle

rootProject.name = 'example-app'

build.gradle

plugins {
    id 'ru.kinca.google-drive-uploader' version '1.1.0'
    id 'application'
}

mainClassName = 'ru.kinca.example.App'

googleDrive {
    destinationFolder = 'myapp/distributions'

    file = files(distZip).singleFile
    clientId = driveClientId
    clientSecret = driveClientSecret
}
uploadToDrive.dependsOn distZip

The application distribution will be packed to a ZIP-file and uploaded to myapp/distributions/example-app.zip and shared publicly for reading.
