Butterknife: Butterknife 10.0.0 and Feature plugin do not work

[frogermcs]

I mentioned it here: https://github.com/JakeWharton/butterknife/pull/1402 but MR is already closed.

In project with com.android.feature, the location of R.txt is a bit different, what leads to an error

> java.io.FileNotFoundException: .../my_app/features/{module}/build/intermediates/symbols/feature/debug/R.txt (No such file or directory)

It seems that Gradle Plugin 3.3 puts this file into:
.../my_app/features/{module}/build/intermediates/symbols/debug/R.txt
(no /feature/ part)

@frogermcs can you be more specific ? We are using gradle 3.3 and BK 10 and we have no such issue..

[JakeWharton]

Are you using the feature plugin?

[frogermcs]

Yes we use apply plugin: 'com.android.feature' instead of library.

[JakeWharton]

Sorry I wasn't replying to you. That was in the original report and is presumably the source of the trouble.

Duplicate of #1451

[JakeWharton]

I think you have that backwards

[TAGASK]

After several tests, it turned out that this error occurs when the R2 file generation is used in the baseFeature and in an instant app feature at the same time.
I ll advice to move all the UI codebase which needs the R2 class file from the the baseFeature to the specific module (Instant app feature) you are using.
Hope this ll help.

[frogermcs]

Hey, while it can be great workaround, it's not that simple in our case. The multimodule architecture becomes pretty complex and there are UI components modules reused in higher level ones.

[TAGASK]

Anyway it doesn't come from the butterknife plugin, if there is a failure it s because the file is not created previously :
/build/intermediates/symbols/feature/debug/R.txt (No such file or directory)
This file is not generated by butterKnife, so it's in feature or baseFeature that there is an issue.

[frogermcs]

This file is generated in other directory like I mentioned in first message.

Gets this one:

* What went wrong:
Execution failed for task ':features:transaction:generateDebugFeatureR2'.
> java.io.FileNotFoundException: ...dev/jenkins/workspace/d-app_feature_migrate_AS_33-LM7AGHCBO6KD7O3WL344QWYUEFXRSWGFGB6I23T74ZK4WV7FCPVA/features/transaction/build/intermediates/symbols/feature/debug/R.txt (No such file or directory)

While R.txt is there, but in different dir:

.../features/transaction/build/intermediates/symbols/debug/R.txt

[TAGASK]

.../features/transaction/build/intermediates/symbols/debug/R.txt

this one contains the res id and layout of the baseFeature with all the resource of the dependecies.

java.io.FileNotFoundException: ...dev/jenkins/workspace/d-app_feature_migrate_AS_33-LM7AGHCBO6KD7O3WL344QWYUEFXRSWGFGB6I23T74ZK4WV7FCPVA/features/transaction/build/intermediates/symbols/feature/debug/R.txt
this one should contains the id and layout of the res of the feature only.

Use only the symbol/debug/R.txt ll not resolve the issue.

[frogermcs]

Ahh I see...

Also I recreated this problem in much simpler project.

Here's the branch with code: https://github.com/frogermcs/MultiModuleGithubClient/tree/update_to_AS_3.3
And output from the build: https://travis-ci.com/frogermcs/MultiModuleGithubClient/jobs/179287644

Interesting fact is that in this chain of features:
repositories -> repository -> base
only the middle one doesn't have /symbols/feature/debug/R.txt 🤔

Early tests of the fix in gradle plugin 3.5.0 alpha12 show that it may be fixed now. :)

Great! I'm going to preemptively close. Let me know if anything changes in the future.

So exactly which was the solution? I don´t have the plugin and I'm able to use your project. This is what I have; however, my projects fail when R2 is not found.

dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'
        classpath 'com.jakewharton:butterknife-gradle-plugin:10.1.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

In the sub-project I'm using apply plugin: 'com.android.dynamic-feature', maybe that's my issue.
Thanks!
