Unable to build project with upgrade to android gradle 3.0

Question

I am trying to update android JavaVersion.VERSION_1_7 to JavaVersion.VERSION_1_8. I am using Android Studio 3.0 Beta 2 from canary branch. It looks like I did things by the book , but I am unable to compile my project with the new setup. I have provided a brief description of of my gradle file below and the error log as an output of assembling the build.

Here's the buildscript part of my gradle file.

Gradle buildscript

buildscript {
    repositories {
        jcenter()
        maven { url 'https://maven.google.com' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-beta2'

        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'

        classpath 'org.aspectj:aspectjtools:1.8.6'
    }
}

Gradle android

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.1"

    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 25

        renderscriptTargetApi 23
        renderscriptSupportModeEnabled true
    }

    // API 23 removes the http apache libraries, we require this to continue using them. We should
    // eventually move away from them and then remove this
    useLibrary 'org.apache.http.legacy'

    flavorDimensions "default"

    productFlavors {
        // product flavors here
    }
}

I found the error. I actually had to remove the "@" character from the attribute name:

Before:

<style name="slideUpAnimation">
    <item name="@android:windowEnterAnimation">@anim/slide_in_bottom</item>
    <item name="@android:windowExitAnimation">@anim/slide_out_bottom</item>
</style>

After

<style name="slideUpAnimation">
    <item name="android:windowEnterAnimation">@anim/slide_in_bottom</item>
    <item name="android:windowExitAnimation">@anim/slide_out_bottom</item>
</style>
