Cannot compile latest version on Android

[kingston]

I was able to integrate the library just fine on iOS, but when I tried to compile on Android, I got the following error:

FAILURE: Build failed with an exception.

* Where:
Build file '/.../node_modules/@segment/analytics-react-native/android/build.gradle' line: 16

* What went wrong:
A problem occurred evaluating project ':@segment_analytics-react-native'.
> Could not get unknown property 'defaultKotlinVersion2' for object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

I was able to get it to compile on 1.1.0 but the latest 1.1.1-beta version appears to error out on compile.

Digging around - not sure if somehow this commit 3c29a88#diff-53e51ee8427e664794253d1b95f14fcb caused some incompatibilities with my build setup?

OS: Mac OSX 10.15.3
Command: react-native run-android
React Native: 0.61.4

Hi @kingston,

A conversation was started in the PR for that, not the best place for it, but to repeat that info here:

not seeing that error here. In packages/android/build.gradle, could you try removing line 4, and editing lines 16 and 45 where it's used with the actual 1.3.21 value and see if that resolves it for you?

[kingston]

Actually - I narrowed it to just line 16. Once I replaced line 16 with 1.3.21 it worked fine:

buildscript {
    repositories {
        jcenter()
        maven { url 'https://maven.google.com' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.21"
    }
}

Did some more digging. Found two blog posts that seem relevant:

• https://wtanaka.com/node/8111
• https://greggigon.com/2011/06/14/build-script-and-project-level-variables-gradle/

Not sure why yours works though - maybe different version of Gradle that changed this behavior?

I am facing a similar issue:

FAILURE: Build failed with an exception.

* Where:
Build file '/MixPanelTest/node_modules/@segment/analytics-react-native/android/build.gradle' line: 16

* What went wrong:
A problem occurred evaluating project ':segment_analytics-react-native'.

I did a RN fresh install and just

yarn add @segment/analytics-react-native
yarn react-native link
react-native run-android

@kingston Sorry, which version of this library are you installing?

[bsneed]

Ok, I'm gonna ping the author of the PR for this and see what he can possibly do here. If nothing, we'll revert that commit and issue a follow on beta. The defaultKotlinVersion bits are so it can be supplied from the developer using the library, so if that goes back to being hard coded, might as well revert the PR and bump the kotlin version #.

[bsneed]

ps. @kingston thanks so much for digging into that, much appreciated!

[rborn]

@bsneed any news about this? it breaks any build we try to do, and 1.1.0 doesn't want to play noce with RN 0.62, at least on my end.
Thanks 😻

[bsneed]

@rborn I can't speak to 0.62, haven't tried that yet. However, this particular issue mentioned here will get resolved by EOW.

[rborn]

@bsneed thank you 😻

[bsneed]

The fix for this is pending in PR #157

hi @bsneed !! thank you so much for your quick pr. however, after having updated to the new version (1.1.1-beta.1), the build fails at line 45 now

* Where:
Build file '/Users/sarahdenaci/code/MobileApp/node_modules/@segment/analytics-react-native/android/build.gradle' line: 45

* What went wrong:
A problem occurred evaluating project ':@segment_analytics-react-native'.
> Could not get unknown property 'defaultKotlinVersion' for object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

If I add
def defaultKotlinVersion = '1.3.21'
to line 42 it builds successfully.

Could you please advise? Thank you in advice for all your help :)

[rborn]

@sdenaci could you try and move def defaultKotlinVersion = '1.3.21' outside the buildscript block (above) ?
