Answer 1

If you are attempting to update your Gradle 1.9 project to Gradle 1.10 using

task wrapper(type: Wrapper) {
    gradleVersion = '1.10'
}

and command ./gradlew wrapper you will get the same error as above.

Solution is to install Gradle 1.10 onto your machine and upgrade your project not using the wrapper

gradle wrapper

Ok i guess android studio has answer for this to get this bug out using GUI,

I had this error like this...

after updating the plugins i was facing another issues while building,

so changes the gradle setting to default as shown in the image,

After this build was successful.

Answer 3

For those who are using 2.1 version of studio, replace classpath 'com.android.tools.build:gradle:2.1.0-rc1' with classpath 'com.android.tools.build:gradle:2.1.0'. This solved my problem.

Answer 4

If you're using the command line to create the project like so:

android create project -g -v 1.2.2 --target 1 --name rtest --path rtest --activity MainActivity --package com.mydomain.rtest

The project is created to use version 1.2.2 of the android-gradle-plugin, but the project is initialised with gradle 1.12, which isn't compatible.

To fix it, do the following:

1. Open rtest/gradle/wrapper/gradle-wrapper.properties and set distributionUrl to the release you want; for example: http\://services.gradle.org/distributions/gradle-2.2.1-all.zip (don't forget to escape the colon - yes, that makes me smile too);
2. Open build.gradle and change runProguard false to minifyEnabled false;
3. ./gradlew clean && ./gradlew assembleDebug
4. I also remove the hidden .gradle folder, but I'm not sure if it's necessary

And it all works again.

Answer 5

Google made a mistake with version 0.7.2 of the Gradle plugin:

Note: 0.7.2 requires Java7. This is a mistake. Use 0.7.3 instead.

Release 0.7.3 re-enables Java6 support. Declaring Gradle 0.7.3 in my build files does indeed resolve this for me.

No one is perfect :)

Answer 6

I got it working using Gradle 1.10 with the Gradle plugin 0.8.0.

// /build.gradle
// Top-level build file where you can add configuration 
// options common to all sub-projects/modules.
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.8.+'
    }
}
