Android应用io.fabric插件失败：找不到verboseGradlePlugin属性

First off, let's address the root cause here: the old Fabric plugin you're using is no longer maintained by Google, and it has compatibility issues with older Gradle/Android Gradle Plugin (AGP) versions like your setup (Gradle 4.4 + AGP 3.1.2). Here are two actionable solutions, ordered by recommendation:

Solution 1: Migrate to Firebase's Native Crashlytics Plugin (Recommended) #

Google has fully integrated Crashlytics into Firebase, so you don't need the Fabric plugin anymore. Follow these steps to clean up and reconfigure:

1. Remove all Fabric-related configurations

   • In your project-level build.gradle, delete the Fabric classpath entry:

     classpath 'io.fabric.tools:gradle:x.x.x' // Remove this line
     

   • In your app-level build.gradle, remove the Fabric plugin apply line:

     apply plugin: 'io.fabric' // Remove this line
     

   • Delete any fabric.properties or crashlytics.properties files from your project.
   • Remove the old Crashlytics dependency:

     implementation 'com.crashlytics.sdk.android:crashlytics:x.x.x' // Remove this
     

2. Add Firebase Crashlytics compatible with your AGP version

   • In project-level build.gradle, add the Firebase Crashlytics classpath (pick a version that supports AGP 3.1.2; 2.9.2 is a safe bet):

     dependencies {
         classpath 'com.android.tools.build:gradle:3.1.2'
         classpath 'com.google.gms:google-services:4.3.10' // Ensure this is compatible
         classpath 'com.google.firebase:firebase-crashlytics-gradle:2.9.2'
     }
     

   • In app-level build.gradle, apply the Firebase Crashlytics plugin after the Android plugin:

     apply plugin: 'com.android.application'
     apply plugin: 'com.google.firebase.crashlytics' // Add this
     apply plugin: 'com.google.gms.google-services' // Keep this if you use other Firebase services
     

   • Add the Firebase Crashlytics dependency:

     dependencies {
         implementation 'com.google.firebase:firebase-crashlytics:18.2.10'
     }
     

3. Sync and test
   Clean your project (./gradlew clean), restart Android Studio, and sync your Gradle files. This should eliminate the Fabric plugin entirely and resolve the property error.

Solution 2: Fix the Fabric Plugin Property Issue (If You Must Keep Fabric) #

If you absolutely need to stick with the old Fabric plugin, the error likely stems from a misconfigured property type somewhere in your build files. Here's what to check:

• Check for incorrect property assignments: Ensure you haven't accidentally set verboseGradlePlugin as a string instead of a boolean. For example, avoid lines like:

  verboseGradlePlugin = "true" // Wrong: this is a string
  

  It should be:

  verboseGradlePlugin = true // Correct: boolean type
  

• Use a Fabric plugin version explicitly tested with AGP 3.1.2: Try version 1.26.1 (some users report this works better with older AGP versions than 1.24.0/1.25.4). Update your project-level classpath to:

  classpath 'io.fabric.tools:gradle:1.26.1'
  

• Check Gradle system properties: When running Gradle tasks, ensure you're passing the property as a boolean, not a string. Use:

  ./gradlew assembleDebug -DverboseGradlePlugin=true
  

  (Avoid quotes around true/false.)

A final note: Your Gradle and AGP versions are quite outdated (released in 2018). If possible, consider upgrading them to a more recent stable version (e.g., AGP 4.2.x with Gradle 6.7.1) to avoid compatibility issues with Firebase services long-term.
