Gradle: Could not create an instance of type com.a

问题:

I have an issue with Gradle running on Jenkins:

A problem occurred evaluating project ':app'.
> Failed to apply plugin [id 'com.android.application']
   > Could not create an instance of type com.android.build.gradle.internal.dsl.SigningConfig_Decorated.

Top level build.gradle

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

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

Line the error occurrs on (file app/build.gradle):

apply plugin: 'com.android.application'

I tried using Gradle wrapper/Invoke Gradle, and with different versions down to 2.10. I'm using "Force GRADLE_USER_HOME to use workspace".

Encountered the same issue after updating to Gradle 2.10. I had to create a folder named /usr/share/tomcat/.android and give it all permissions (chmod a+rwx .android). That fixed the issue for me.

You are probably missing the Android SDK build tools. If you open the gradle.build file using Android Studio it can help you install the required tools. Or have a look at How to install Android SDK Build Tools on the command line?
