Gradle build fails on enabling data binding

i am facing a strange issue. I have decided to enable databinding in my project and in order to do so i followed the developer.android guidelines. So i added the dataBinding tag in my gradle file and gradle sync fails and shows the following error.
Error:java.lang.NullPointerException
Error:Execution failed for task ':app:mergeDebugResources'.
Error: java.lang.NullPointerException
and no other information is there so that i can track down the problem. My gradle file is below:

The problem with Databinding (and Dagger as well) is that, if there's an error, a lot of files are not generated, giving lots of errors. So much in fact, that the default output of javac is not enough to see the error message at the bottom.
Most of the time, it helps to increase the maximum number of error output lines, by adding this to your build.gradle
gradle.projectsEvaluated {
tasks.withType(JavaCompile) {
options.compilerArgs << "-Xmaxerrs" << "1500"
}
}

Error:Execution failed for task ':app:transformJackWithJackForRelease'

I am getting the following error while building signed APK
Error:Execution failed for task ':app:transformJackWithJackForRelease'
com.android.build.api.transform.TransformException:
com.android.builder.core.JackToolchain$ToolchainException: Jack configuration exception.
Error while parsing '/Users/omprakash/.android/build-cache/44cf3550bd071d5e2184a0fbb6e8da24ff70e1cb/output/proguard.txt':2
The app is running fine in debug mode.
But when I am building the signed APK I am getting the above error. Tried changing the buildToolVersion but it didn't help. I also have MyApplication class extending MultiDexApplication.

Please help me to resolve this issue

Try to add following version of intercom library instead of version you are using :
compile 'io.intercom.android:intercom-sdk-fcm:4.0.0'
OR
compile 'io.intercom.android:intercom-sdk-fcm:4.0.4'

I think facebook sdk comes with v4-support library exclude that and try.
compile ('com.facebook.android:facebook-android-sdk:4.6.0') {
exclude module: 'support-v4'
}

Update gradle to experimental version - Error

I'm following the guide http://tools.android.com/tech-docs/new-build-system/gradle-experimental to update my gradle configuration in order to use ndk.
Pluggin version: 0.6.0-alpha5
Gradle version: 2.10
After the changes, I get the error:
Gradle sync failed: Cause: com.android.build.gradle.managed.AndroidConfig$Impl
Here is my build.gradle. Did I forgot something or made a mistake ?
apply plugin: 'com.android.model.application'
model {
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "com.appid"

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

proguardFiles.add(file('proguard-android.txt'))
proguardFiles.add(file('proguard-rules.pro'))
}
}
ndk {

}
packagingOptions {

exclude 'META-INF/NOTICE'
}
}
}

compile 'com.squareup.okhttp3:okhttp:3.0.0-RC1'
// Junit
testCompile 'org.robolectric:robolectric:3.0'
}

I believe that buildTypes should be outside the "android" block. Also, possibly replace "defaultConfig" with "defaultConfig.with" I followed build.gradle structure in this answer. Then Gradle finally was able to build.

Maybe this will help.
