Question by mauxno · Jul 06, 2021 at 07:26 PM · build-error

Build failed because of gradle version ? (A problem occurred evaluating project ':launcher') Unity 2019.4

Hello.

I'm trying to build my project using gradle but it fails with a few errors, after some time looking into each error alone I've managed to fix the errors by adding a few lines to config files like AndroidManifest.xml and gradle.properties (enabling Multidex for example), as I don't think those errors are related I'll go straight into the remaining error, but feel free to ask if you think that might be related.

When I try to build, I get the following error:


CommandInvokationFailure: Gradle build failed. C:/Program Files/Unity/Hub/Editor/2019.4.28f1/Editor/Data/PlaybackEngines/AndroidPlayer\OpenJDK\bin\java.exe -classpath "C:\Program Files\Unity\Hub\Editor\2019.4.28f1\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\gradle\lib\gradle-launcher-5.1.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx4096m" "assembleRelease"

stderr[

FAILURE: Build failed with an exception.

  • Where: Build file 'C:\Chaos Age\Temp\gradleOut\launcher\build.gradle' line: 2

  • What went wrong: A problem occurred evaluating project ':launcher'.

    Could not get unknown property 'android' for project ':launcher' of type org.gradle.api.Project.

  • Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

I managed to find a solution that apparently address my issue at https://stackoverflow.com/questions/62071166/could-not-get-unknown-property-android-for-project-shared-preferences-of-ty Although its Android Studio and I'm developing only on Unity, according to this answer the problem is that there are some gradle version declared wrong somewhere, the same should apply to Unity.

Looking further into this matter I've found some comments on a build.gradle file.

[...] alt text [...]

According to the links, Unity 2019.4 comes with Gradle 5.1.1 https://docs.unity3d.com/Manual/android-gradle-overview.html And Gradle 5.1.1 is compatible with Android Gradle Plugin 3.4.0 https://developer.android.com/studio/releases/gradle-plugin#updating-gradle

I could'nt find any way to confirm those are indeed installed neither to confirm those are correctly declared, besides I can't say for sure what is causing this error. I hope someone can shed some light on my situation.

Thanks in advance.

For anyone that might come across this, I've managed to get rid of this problem on Assets/Reimport All, this caused some other errors but not "A problem occurred evaluating project" and I eventually managed to solve them all.
