Build fails with 'Program type already present: android.arch.core.util.Function' #1357

Could you try adding this dependency to your app:
|
|
@samtstern thanks for your response. I tried, but the same error was generated. 😞 |
|
@jcmbmercadoni this may be a duplicate of #1344, but let's dive into it anyway. I can reproduce this error with only two dependencies: dependencies {
// Support
implementation 'com.android.support:appcompat-v7:27.1.1'
// FirebaseUI
implementation 'com.firebaseui:firebase-ui-firestore:4.0.1'
}So there has to be some issue there that's causing D8 to get angry. |

@SUPERCILEX this is so simple yet ... so broken. Do you have any ideas / have you seen this before? Some more datapoints:
These are all the dependencies of <dependencies>
<dependency>
<groupId>android.arch.lifecycle</groupId>
<artifactId>runtime</artifactId>
<version>1.1.1</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>android.arch.lifecycle</groupId>
<artifactId>viewmodel</artifactId>
<version>1.1.1</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>com.android.support</groupId>
<artifactId>support-annotations</artifactId>
<version>27.1.1</version>
<scope>runtime</scope>
</dependency>
</dependencies>
These are the dependencies of <dependencies>
<dependency>
<groupId>android.arch.lifecycle</groupId>
<artifactId>runtime</artifactId>
<version>1.1.0</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>android.arch.lifecycle</groupId>
<artifactId>viewmodel</artifactId>
<version>1.1.0</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>com.android.support</groupId>
<artifactId>support-annotations</artifactId>
<version>27.1.0</version>
<scope>runtime</scope>
</dependency>
</dependencies> |

The issue does not seem to exist with Support But |
|
You can work around this by specifying a specific core dependency: |
|
@kurtisnelson I swear I tried that .... sigh I feel like such an idiot. Confirmed this works, thank you! dependencies {
// Support
implementation 'com.android.support:appcompat-v7:27.1.1'
// FirebaseUI
implementation 'com.firebaseui:firebase-ui-common:4.0.1'
// Arch
implementation "android.arch.core:runtime:1.1.1"
implementation "android.arch.core:common:1.1.1"
} |

Is this considered a solution or a workaround? |
|
@troy21688 unfortunately that is a "solution". Gradle is not always great at dependency management so many times you have to declare a hard version of a transitive dependency in your top-level Of course if you have a better solution we are all ears! |
|
Do you feel it is something Firebase will attempt to address in future dependencies? Or should I simply try to continue to isolate the conflict? |
|
I have been tweaking my code, I was able to eliminate some dependencies but am still having the issue. What would be best to post on my end to help resolve? |
|
@troy21688 post your whole dependencies block. If you can reproduce this with only a subset of dependencies, please post that. |
|
Yeah, and the output of Someone is using a version smaller than |
|
@SUPERCILEX did they really do that in a post-1.0.0 non-major release? 🤦♂️ |
|
Hehe, my thoughts exactly. It happened back in March though, so not sure why everything is blowing up now. 🤷♂️ |
|
Is it anticipated that Firebase will fix it in a future release? |
|
This isn't really our fault which means we can't do a whole lot—it's a side effect of us using lifecycle components to build FUI. Regardless, those logs would help us figure out your particular dependency conflict. |

Thanks! Would you mind sharing the output of running |
