Android Data Binding NoSuchMethodError

Question

I'm not able to setup my project to use Android Data Binding. This is my build.gradle :

apply plugin: 'com.android.databinding'


buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0-beta2'
        classpath "com.android.databinding:dataBinder:1.0-rc4"
    }
}

android {
    ...
    dataBinding {
        enabled = true
    }

    compileSdkVersion 21
    buildToolsVersion "20.0.0"
    ...
}

When I build, I get this error:

[data binding plugin]: failed to setup data binding

java.lang.NoSuchMethodError: android.databinding.tool.LayoutXmlProcessor.(Ljava/lang/String;Ljava/util/List;Landroid/databinding/tool/writer/JavaFileWriter;IZ)V

EDIT

I have modified build.gradle :

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
    }
}

But I still get the same error. Also I have this apt config:

apt {
    arguments {
        androidManifestFile variant.outputs[0].processResources.manifestFile
    }
}

Since I'm using AndroidAnnotations.

Answer 1

You should now set it up with 1.5.0 and without the explicit data binding import:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
    }
}

Android Data Binding 1.0 was released as part of the Android gradle plugin.

Answer 2

Though George's answer is correct I think it's important to make it clear what should be in each one of the build.gradle files.

So, in the project's build.gradle file we should have:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
    }
}

And in the app's build.gradle file there should be:

apply plugin: 'com.android.application'
// No need to add it as a plugin
// apply plugin: 'com.android.databinding'

android {
    ...
    dataBinding {
        enabled = true
    }

    compileSdkVersion <latest>
    buildToolsVersion <latest>
    ...
}

We don't need to add apply plugin: 'com.android.databinding' in the app's build.gradle file because, as George said:

Android Data Binding 1.0 was released as part of the Android gradle plugin.

Check the Data Binding Guide for more details.
