Failed to apply plugin Android Gradle plugin 3.0.0

问题:

Using the latest Android Studio 3.0 Canary 5

Here's the error:

Error:(1, 1) A problem occurred evaluating project ':app'.

Failed to apply plugin [class 'com.android.build.gradle.api.AndroidBasePlugin'] Android Gradle plugin 3.0.0-alpha5 must not be applied to project [path_to_my_project] since version 3.0.0-alpha5 was already applied to this project

Tried: cleaning, rebuilding, opening/closing. Not working.

any ideas ?

[LATER EDIT] Solution: Migrate to Canary 8+ and all should be ok.

from this thread on reddit: https://www.reddit.com/r/androiddev/comments/6kjl8b/android_studio_30_canary_5_is_now_available/djmuv0o/ killing daemons fixed the problem for me.

./gradlew --stop

回答2:

This worked for me:

Deactivate Configuration On Demand

In gradle.properties:

org.gradle.configureondemand=false

Then stop the daemon in a terminal window:

gradlew.bat --stop

Now everything works again.

Versions used:

• Android Studio 3.0 Canary 5
• gradle: gradle-4.1-milestone-1
• android gradle plugin: com.android.tools.build:gradle:3.0.0-alpha5

UPDATE
After upgrading to Android Studio 3.0 Beta 2 I can reactivate Configuration on Demand and everything works fine.

Migrating the gradle version from 3.0.0-alpha5 to 3.0.0-alpha7 saved my day !!

回答4:

I got the issue and realized the issue related with caches. You have to invalidate caches of Android studio by select File-> Invalidate Caches/Restart. It worked for me. The issue was resolved.

回答5:

Open a terminal and write

./gradlew --stop 

In gradle.properties make sure you don't have funny stuff

Notice that there are no custom jvmargs...

org.gradle.daemon=true
org.gradle.parallel=true
org.gradle.configureondemand=false

Include the google() repo in build.gradle (project one)

there's how mine look like

build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {

  repositories {        
    jcenter()
    google()
    maven { url "http://objectbox.net/beta-repo/" }
  }
  dependencies {
    classpath 'io.objectbox:objectbox-gradle-plugin:0.9.12.1'
    classpath 'com.android.tools.build:gradle:3.0.0-alpha5'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
  }
}

allprojects {
  repositories {
    maven { url 'https://jitpack.io' }
    jcenter()
    google()
    maven { url "http://objectbox.net/beta-repo/" }
  }
}

task clean(type: Delete) {
  delete rootProject.buildDir
}

lastly the support library versions in the app build.gradle file

build.gradle

...
  //----- Support Libs
  implementation 'com.android.support:appcompat-v7:26.0.0-beta2'
  implementation "com.android.support:design:26.0.0-beta2"
  implementation "com.android.support:recyclerview-v7:26.0.0-beta2"
  implementation "com.android.support:cardview-v7:26.0.0-beta2"
...

I had the same issue, I closed Android Studio and opened again, I noticed that it automatically applied these changes to the following files and everything worked fine:

build.gradle: changed the class path of Gradle from:

dependencies {
        classpath 'com.android.tools.build:gradle:2.3.1'
    }

to

dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-alpha5'
    }

gradle-wrapper.properties: from

distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-all.zip

to

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-milestone-1-all.zip

I already tried all the solutions including Clean, Rebuild, Invalidate Project

But nothing is working but i figured it out.

For temporary just downgrade your gradle plugin version to stable version

classpath 'com.android.tools.build:gradle:2.3.2'

Replace your alpha line with this line. And have fun.. :)
