Summary:
Gradle tasks for publishing to bintray and jcenter, mavencentral; snapshot buidls go to oss.sonatype.org
Those gradle changes adds tasks:
bintrayUpload - publishing on bintray, in 'facebook' org
uploadArchives - uploading to maven repos
Gradle tasks are copied from facebook open sourced libraries like https://github.com/facebook/litho, https://github.com/facebookincubator/spectrum
To do the publishing we need to provide somehow (e.g. in ~/.gradle/gradle.properties)
```
signing.keyId=
signing.password=
signing.secretKeyRingFile=
bintrayUsername=
bintrayApiKey=
bintrayGpgPassword=
SONATYPE_NEXUS_USERNAME=
SONATYPE_NEXUS_PASSWORD=
```
android/libs/fbjni is submodule, to be able to add publishing tasks to it (it needs to be published as separate maven dependency) - I created `android/libs/fbjni_local` that has only `build.gradle` with release tasks.
pytorch_android dependency for ':fbjni' changed from implementation -> api as implementation treated as 'private' dependency which is translated to scope=runtime in maven pom file, api works as 'compile'
Testing:
it's already published on bintray with version 0.0.4 and can be used in gradle files as
```
repositories {
maven {
url "https://dl.bintray.com/facebook/maven"
}
}
dependencies {
implementation 'com.facebook:pytorch_android:0.0.4'
implementation 'com.facebook:pytorch_android_torchvision:0.0.4'
}
```
It was published in com.facebook group
I requested sync to jcenter from bintray, that usually takes 2-3 days
Versioning added version suffixes to aar output files and circleCI jobs for android start failing as they expected just pytorch_android.aar pytorch_android_torchvision.aar, without any version
To avoid it - I changed circleCI android jobs to zip *.aar files and publish as single artifact with name artifacts.zip, I will add kostmo to check this part, if circleCI jobs finish ok - everything works :)
