Unable to build app via gradle after installing sentry

[nitish24p]

Platform:

• Android

I have successfully installed the sentry client on my android app for local development, however on building the app and initialising proguard, my app build fails and i get the following error. Are there any rules that i have to enable to allow the build.

Warning: Exception while processing task java.io.IOException: Please correct the above warnings first.
:app:transformClassesAndResourcesWithProguardForReleaseGiant FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformClassesAndResourcesWithProguardForReleaseGiant'.

[HazAT]

Hey, I need a bit more output than that, can you run it with
./gradlew assembleRelease --stacktrace

[nitish24p]

Sure

* What went wrong:
Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.
> Job failed, see logs for details

* Try:
Run with --info or --debug option to get more log output.

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.

Can you also please update to the latest version 0.22.0, we've changed a few things regarding gradle.

[nitish24p]

Sure will try and let you know.

Just to clear things up, have you guys seen the proguard documentation: https://docs.sentry.io/clients/java/modules/android/#proguard

I just followed the documentation and had no problem I am not really sure if the is Sentry related.

[antoinerousseau]

Oh I didn't see that page, thanks.
Unfortunately Gradle can't compile it:

A problem occurred evaluating project ':app'.
> Failed to apply plugin [id 'com.android.application']
   > Minimum supported Gradle version is 3.3. Current version is 2.14.1. If using the gradle wrapper, try editing the distributionUrl in /Users/antoine/Sites/tribeez/android/gradle/wrapper/gradle-wrapper.properties to gradle-3.3-all.zip

(this error appears when adding classpath 'io.sentry:sentry-android-gradle-plugin:1.5.3' to the dependencies although it says here that the gradle dependency is 2.X)

Could this be because my RN version is 0.42.3 and this plugin is for a newer one?
But it looks like RN still relies on Gradle 2.14.1:

@antoinerousseau As far as I know it shouldn't be a problem updating gradle to 3.3, I've tried it before and it worked without any problems.

[antoinerousseau]

I tried but it needs the SDK build tools 25.0.0 instead of 23.0.1, and when I set buildToolsVersion to 25.0.0 in app/build.gradle I get:

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:_debugApk'.
   > A problem occurred configuring project ':react-native-sentry'.
      > The SDK Build Tools revision (23.0.1) is too low for project ':react-native-sentry'. Minimum required is 25.0.0

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Which makes sense here: https://github.com/getsentry/react-native-sentry/blob/master/android/build.gradle#L6

@antoinerousseau I am able to build the app with 23.0.1 and 25.0.0 so I am not really sure how to help, it must be something with your setup.

[antoinerousseau]

@HazAT with RN 0.42 ?

I tried with compileSdkVersion 22 and 23, the buildToolsVersion is 23.0.1, minSdkVersion is 16 and targetSdkVersion is 23...

my proguard-rules.pro is the same than RN's one

Can you try to add -dontwarn io.sentry.**?

[antoinerousseau]

I tried with -dontwarn io.sentry.** { *; } without luck, but just tried with -dontwarn io.sentry.** and it builds! And the app seems to work. Thanks!! :)
