🔥 #420 🔥

looking at this line: https://github.com/Microsoft/code-push/blob/master/cli/script/command-executor.ts#L905

I can see that the .parseFile function doesn't hit the catch, becuse I am not seing an error about being Unable to parse the gradlefile. It appears at face value to be dying in the deep-assign dependency that is used by gradle-to-js

[the-simian]

The problem appears to be in gradle-to-js. I'll submit an error report there.

Hey it seems that the problem fully lies in the underplaying gradle-to-js module, and I've submitted an issue there, since that's where it really belongs. I think its safe to close this, so I shall do so.

I've produced a very minimal example of the issue here that clearly proces its in the underlying module: https://github.com/the-simian/gradle-to-js-test

Thanks!

Hey @the-simian, thank you for your great investigation! All this information will be very useful for anyone who can get this error in future! We are appreciating your help with this.
Will try to monitor when this will be fixed in gradle-to-js package and will update our dependency accordingly.

If anyone else is still having trouble with this - I just commented out almost my entire gradle file (but left the version section) and was able to release. You can do the same until the gradle-to-js issue is fixed.

I have the same issue in v2.0.2-beta

[ruslan-bikkinin]

hi, @dluksza, we've been updated gradle-to-json to version 1.0.1 which has a fix for the issue and will release new code-push cli version soon. Can you please update from master to see if the issue is fixed?

[akshetpandey]

@ruslan-bikkinin I am also running into this issue and since neither yarn not npm support installing packages from a subfolder of a git repo, would it be possible to create a release tag from master called master or next.

[ruslan-bikkinin]

@akshetpandey feel free to create fork of code-push repo and use it.

[dluksza]

@ruslan-bikkinin is there any guide how to update to master?

btw. For me removing dependences section from android/app/build.gradle fixed this issue and was able to push code to server.

[ruslan-bikkinin]

@dluksza please follow these steps:

git clone git@github.com:Microsoft/code-push.git
cd code-push
npm i && gulp install && gulp link && gulp build
cd /path/to/your/app
#then you can use local code-push cli by executing this command
node path/to/cloned/code-push/cli/bin/script/cli.js

@ruslan-bikkinin I can that this error does not occur on current master (HEAD commit: f8932552024bd21936c2584973196521ce216484). Any ideas when it will be released?

[ruslan-bikkinin]

@dluksza we are planning to release new version at the beginning of next week.
