I'm trying to build our RN project on Microsoft AppCenter and facing this issue after integrating Sentry for Android.

When this command executes - [command]/Users/vsts/agent/2.131.0/work/1/s/android/gradlew -DMOBILECENTER_KEYSTORE_PASSWORD=******** -DMOBILECENTER_KEY_ALIAS=******** -DMOBILECENTER_KEY_PASSWORD=******** -DMOBILECENTER_BUILD_VERSION=1524662574 -DAPPCENTER_KEYSTORE_PASSWORD=******** -DAPPCENTER_KEY_ALIAS=******** -DAPPCENTER_KEY_PASSWORD=******** -DAPPCENTER_BUILD_VERSION=1524662574 -p android clean :app:assembleRelease

I am getting this error..

Would love some help here :)

So I was able to fix this issue by disabling the flavorAware option. When using this option, the build task was looking for a sentry.${flavor}.properties (where flavor is release or debug) file which was not available in the project. I just had sentry.properties.

Thanks for clearing this up, will close this issue. 👍

I found this thread as I got the same error, however we did not use Sentry in our project, and the issue we had is appcenter-pre-build.sh: line 32: =: command not found I fixed it, and the error was resolved!

so, in our case, it was an issue related to an error in the appcenter-pre-build.sh
