Proguard mappings not uploaded when assembling with Gradle

I am using Sentry 2.0.0 in my Android app.
The Sentry SDK works, but when obfuscating my app, the Sentry plugin is not uploading the Proguard mappings to their server (I can see crashes in the Sentry webapp, but the stacktrace shows obfuscated class names).
When I run the assembleRelease task in gradle I don’t see anything related to Sentry in the log console.

I believe I have configured everything like instructed in the docs (

This is exactly what I have:


apply plugin: ""

sentry {
    autoProguardConfig true
    autoUpload true

android {
    compileSdkVersion 29
    defaultConfig {
        minSdkVersion 26
        targetSdkVersion 29

    buildTypes {

        buildTypes.all {
           proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), ''


        release { 
            minifyEnabled true
            shrinkResources true


dependencies {
    implementation 'io.sentry:sentry-android:2.0.0'
    implementation 'org.slf4j:slf4j-nop:1.7.25'



Gradle version: Gradle 5.6.4

Thank you

hey, what’s the version of the Sentry Gradle Plugin? latest is 1.7.35

Also, what’s the version of the Android Gradle Plugin you are working with?

Could you try to upgrade the Sentry Gradle Plugin and try again? thanks
