Description

Happened after I merged the latest changes for the React Native project into my forked version of it (with only changes to share functionality included there).

Reproducible Demo

1. Create a new React Native project react-native init...
2. Replace existing RN with my forked version
3. Configure all the gradle files: build.gradle replacing the existing RN project with the forked one and settings.gradle so the forked project is included.
4. Try and run the project react-native run-android

---

I have noticed that older versions of RN project used compile 'org.webkit:android-jsc:r174650' instead of compile project(':android-jsc') which is in the current master branch.

That's because we add 64bit cpu support.
We are currently doing some work to make react native fork more easily facebook/react-native-website#653.

[gengjiawen]

For now you can try

docker run --rm --name rn-build -v $PWD:/pwd -w /pwd gengjiawen/react-native /bin/sh -c "./gradlew installArchives"

This may take a while, since it download the docker image and build all the things, after success, you can see something like this in root folder.

android
└── com
    └── facebook
        └── react
            └── react-native

Then remove /android/ in .gitignore.
Also in this way you need not to hack around native dependency like react-native-image-crop-picker.

[gengjiawen]

Also you need this patch #22293.

I tried running the docker command and I received the following message

Unable to find image 'gengjiawen/react-native:latest' locally
docker: Error response from daemon: Get https://registry-1.docker.io/v2/gengjiawen/react-native/manifests/latest: unauthorized: incorrect username or password.
See 'docker run --help'.

[gengjiawen]

Looks like you have some network issue.

[MarkOSullivan94]

I've just copied and pasted exactly what you told me to run. I have no idea what I should do next.

[gengjiawen]

can you try run it on ci ? Circle ci can use ssh debug.

[gengjiawen]

You can also try docker run --rm -it node:11 bash -c "node -p process.versions" to test docker work properly on your machine. If this still not works, there is little I can help since I don't know your network issue.

[MarkOSullivan94]

Yeah that didn't work either. I've never used docker before so I'm not sure if there's any additional steps I need to take to make it work on my machine for RN.

can you try run it on ci ? Circle ci can use ssh debug.

I'm not sure I follow. I don't have Circle CI.

[gengjiawen]

You may need check the basic tutorial about docker. It likes git for me. You will love it.

[MarkOSullivan94]

Okay turns out that I was getting that error message because I was logged in with my email and not my username. Odd.

@gengjiawen where do I run that docker command? In the root level in my fork of the RN project?

[gengjiawen]

yeap.

[MarkOSullivan94]

Okay it's currently downloading. Thank you!

What do you mean by this:

Also in this way you need not to hack around native dependency like react-native-image-crop-picker.

Curious what you mean exactly.

[gengjiawen]

Like this #21776 (comment)

[MarkOSullivan94]

Ah yeah I already had that setup in the project.

Initially had issues with the RN build.gradle file, specifically this section: https://github.com/MarkOSullivan94/react-native/blob/master/ReactAndroid/build.gradle#L6

Had to fix it by removing two of the plugins from that section and using apply plugin instead.

plugins {
    id("maven")
}

apply plugin: 'com.android.library'
apply plugin: 'de.undercouch.download'

After that I was shown this error message

> Task :react-native-android:prepareJSC FAILED

FAILURE: Build failed with an exception.

* Where:
Build file '.../ReactNativeShareExample/node_modules/react-native/ReactAndroid/build.gradle' line: 165

* What went wrong:
Execution failed for task ':react-native-android:prepareJSC'.
> Expected configuration ':react-native-android:compile' to contain exactly one file, however, it co
ntains no files.

[gengjiawen]

Don't remove them. And sync with upstream again as I mentioned earlier.

Looks like this can be closed?

The JSC in Android was updated in December, it's in master now.
