Gradle DSL method not found: 'compile()' while using tesseract library

Question

I have tried to import tesseract ocr project in android studio. While building gradle it showin error as following

Error:(8, 0) Gradle DSL method not found: 'compile()' Possible causes:

The project 'textfairy' may be using a version of Gradle that does not contain the method. Open Gradle wrapper file

The build file may be missing a Gradle plugin. Apply Gradle plugin

My app/build.gradle file

    import java.util.regex.Pattern

    apply plugin: 'com.android.application'
    apply plugin: 'io.fabric'



    import org.apache.tools.ant.taskdefs.condition.Os


    task ndkBuild(type: Exec,description: 'run ndk-build') {
    if (Os.isFamily(Os.FAMILY_WINDOWS)) {
        workingDir 'src/main/jni'
        commandLine 'ndk-build.cmd', '-j',     Runtime.runtime.availableProcessors()

    } else {
        workingDir 'src/main/jni'
        commandLine "$ndkDir/ndk-build", '-j',  Runtime.runtime.availableProcessors()
    }
}

    def matcher = pattern.matcher(manifestText)
    matcher.find()

I have added dependencies also. Please tell me what is the problem. Thank you

You have to change your top-level build.gradle, removing the compile line, and adding the gradle and fabric plugin.

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
        jcenter()
    }
   dependencies {
        classpath 'com.android.tools.build:gradle:1.3.1'
        classpath 'io.fabric.tools:gradle:1.+'
    }
}


allprojects {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
        maven { url "http://dl.bintray.com/populov/maven" }
        jcenter()
        maven {
            url "http://oss.sonatype.org/content/repositories/snapshots"
        }

    }

}

Als if you want to use the libraries:tess-two in your project, you have to add this line inside the dependecies block of your app/build.gradle file

compile project(':libraries:tess-two')

Finally move the apply plugin: 'osgi' at the beginning of the app/build.gradle file

To resolve the ndk issue you have to:

1. add gradle.properties file to root folder of your project
2. add 'android.useDeprecatedNdk=true' to gradle.properties file

Here is my gradle.properties :

android.useDeprecatedNdk=true
