+title: Migrate from sentry-android-gradle-plugin 5.x to 6.0.0
+sidebar_order: 8885
+description: "Learn about migrating from Sentry Android Gradle Plugin 5.x to 6.0.0."
+---
+
+## Build Tooling Requirements
+
+`io.sentry.android.gradle` `6.0.0` updates the minimum supported build tooling. Before upgrading, make sure your project meets all of the following:
+
+- **Gradle**: `8.14.2` or later. The plugin is built against Gradle `8.14.2` and requires that version (or later) at runtime. Older Gradle versions (including `8.10.x`) will fail at Gradle configuration with `java.lang.NoSuchMethodError: 'org.gradle.api.tasks.Exec org.gradle.api.tasks.Exec.setIgnoreExitValue(boolean)'`. See the [Android troubleshooting guide](/platforms/android/troubleshooting/#nosuchmethoderror-during-gradle-configuration-with-sentry-android-gradle-plugin-6x) for the underlying cause.
+- **Android Gradle Plugin**: `7.4.0` or later. To stay on AGP `7.3.X` or below, keep using `io.sentry.android.gradle:5.12.x`.
+- **Kotlin**: language version `1.8` or later.
+
+To update your Gradle wrapper, from your Android project root run:
+
+```bash
+./gradlew wrapper --gradle-version=8.14.2 --distribution-type=bin
+./gradlew wrapper --gradle-version=8.14.2 --distribution-type=bin
+```
+
+Running the command twice is intentional so the wrapper regenerates itself with the new version.
+
+## sentry-cli 3.x and Sentry Self-Hosted Compatibility
+
+`io.sentry.android.gradle` `6.0.0` bundles `sentry-cli` `3.0.0`, which officially supports:
+
+- Sentry SaaS, and
+- Sentry self-hosted version `25.11.1` or later.
+
+Many `sentry-cli` features may continue to work against older self-hosted versions, but support is not guaranteed. If you're on an older self-hosted Sentry instance and can't update yet, stay on `io.sentry.android.gradle:5.x` until you can upgrade self-hosted to `25.11.1` or later.
+
+## Sentry Android SDK Compatibility
+
+`io.sentry.android.gradle` `6.x` ships with a recent `8.x` release of the Sentry Android SDK. If you have `autoInstallation` enabled (the default), the plugin will pin `io.sentry:sentry-android-*` to a compatible version automatically.
+
+If you have `autoInstallation { enabled = false }` (common in brownfield apps and React Native setups), you're responsible for keeping `io.sentry:sentry-*` modules aligned across all Gradle modules in your build. Mismatched Sentry SDK versions can cause `IllegalStateException: Sentry SDK has detected a mix of versions` at app startup, or `NoSuchMethodError` at runtime. To pin the SDK version explicitly without enabling auto-installation, configure each `io.sentry:sentry-*` dependency you use to the same version, or enable auto-installation with a fixed version:
+
+```kotlin
+sentry {
+  autoInstallation {
+    enabled.set(true)
+    sentryVersion.set("8.0.0")
+  }
+}
+```
+
+## React Native and Flutter
+
+If you're using `@sentry/react-native` or `sentry_flutter`, the relevant migration guide for your hybrid SDK already pulls in the matching Sentry Android Gradle Plugin version, but you still need to bump your Gradle wrapper to `8.14.2` or later in your Android project before upgrading the hybrid SDK. See:
+
+- [React Native v7 to v8 migration guide](/platforms/react-native/migration/v7-to-v8/)
+- [Flutter migration guide](/platforms/dart/guides/flutter/migration/)

+## `NoSuchMethodError` During Gradle Configuration With Sentry Android Gradle Plugin 6.x
+
+If you upgrade to `io.sentry.android.gradle` `6.x` and your build fails during Gradle configuration (often when assembling a release variant) with a stack trace similar to the one below, the cause is a Gradle ABI incompatibility, not a problem with native symbol upload:
+
+```
+Caused by: java.lang.NoSuchMethodError: 'org.gradle.api.tasks.Exec org.gradle.api.tasks.Exec.setIgnoreExitValue(boolean)'
+        at io.sentry.android.gradle.util.SentryCliExecKt.asSentryCliExec(SentryCliExec.kt:19)
+        at io.sentry.android.gradle.tasks.SentryUploadNativeSymbolsTask$Companion$register$...
+```
+
+The Sentry Android Gradle Plugin `6.x` is built against Gradle `8.14.2` and requires Gradle `8.14.2` or later at runtime. Older Gradle versions (including `8.10.x`) don't expose the exact `Exec.setIgnoreExitValue(boolean)` signature the plugin was compiled against, so registration of any task that wraps `sentry-cli` (native symbols, ProGuard mapping upload, source context, debug files) fails with `NoSuchMethodError`.
+
+To resolve this, update your Gradle wrapper to `8.14.2` or later. From your Android project root run:
+
+```bash
+./gradlew wrapper --gradle-version=8.14.2 --distribution-type=bin
+./gradlew wrapper --gradle-version=8.14.2 --distribution-type=bin
+```
+
+Running the command twice is intentional so the wrapper regenerates itself with the new version. If you can't update Gradle yet, stay on `io.sentry.android.gradle:5.x` until you can.
+
+Disabling `uploadNativeSymbols`, `includeSourceContext`, or `autoUploadProguardMapping` may appear to "fix" the build, but it only sidesteps the failing task registration. The underlying ABI mismatch remains and other Sentry tasks will hit the same error as soon as they run.
+
 ## Obfuscated stack traces, missing Android-specific context
 
 If stack traces don't get deobfuscated properly, even though <PlatformLink to="/enhance-errors/proguard/">mapping files are uploaded correctly</PlatformLink>, or if Android context information is missing from events, a possible reason is that the SDK is initialized with `Sentry.init` instead of `SentryAndroid.init`.

+## `NoSuchMethodError` After Upgrading To `@sentry/react-native` v8 On Android
+
+If you've upgraded `@sentry/react-native` to v8 and your Android build fails with `java.lang.NoSuchMethodError: 'org.gradle.api.tasks.Exec org.gradle.api.tasks.Exec.setIgnoreExitValue(boolean)'` (originating from `io.sentry.android.gradle.util.SentryCliExecKt.asSentryCliExec`), your Gradle wrapper is older than what the Sentry Android Gradle Plugin `6.x` requires. `@sentry/react-native` v8 ships with `io.sentry.android.gradle` `6.x`, which is built against Gradle `8.14.2` and requires Gradle `8.14.2` or later at runtime. Update `android/gradle/wrapper/gradle-wrapper.properties` to use `8.14.2` or later, then re-run the build.

 ## Support 16 KB Page Sizes on Android
 
 Starting with Android 15, AOSP supports devices with a 16 KB page size. If your app uses NDK libraries (directly or via an SDK), you'll need to rebuild it for compatibility with these devices.
