Having a hard time compiling my app with Robolectric test cases

As the title suggests ever since I worked on Robolectric test cases, I am having a hard time switching back to app and making the android app compile like it used to be.

Every time I try to run the app, I get the following compilation errors:

Error:(35, 23) error: package org.robolectric does not exist
Error:(36, 23) error: package org.robolectric does not exist
Error:(37, 34) error: package org.robolectric.annotation does not exist

Error:(305, 32) error: cannot find symbol variable Robolectric
Error:(317, 25) error: cannot find symbol variable Robolectric

I am aware this is due to the way I made my gradle file, which I pasted it on here:

    sourceSets{
            main {

                manifest.srcFile 'AndroidManifest.xml'
                java.srcDirs = ['src']
                java.exclude {'src/test'}
                resources.srcDirs = ['src']
                aidl.srcDirs = ['src']
                renderscript.srcDirs = ['src']
                res.srcDirs = ['res']
                assets.srcDirs = ['assets']
            }
            test {
                java.srcDirs = ['src/test/java']
            }

            // Move the build types to build-types/<type>
            // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
            // This moves them out of them default location under src/<type>/... which would
            // conflict with src/ being used by the main source set.
            // Adding new build types or product flavors should be accompanied
            // by a similar customization.
            debug.setRoot('build-types/debug')
            release.setRoot('build-types/release')      
    }
dependencies {
    compile fileTree(include: '*.jar', dir: 'libs')
    compile('com.facebook.android:facebook-android-sdk:3.22.0@aar') {
        exclude module: 'support-v4'
    }
    compile files('libs/universal-image-loader-1.9.5.jar')
    compile('com.crashlytics.sdk.android:crashlytics:2.5.0@aar') {
        transitive = true;
    }
    compile files('libs/KochavaSDK.jar')
    compile files('libs/Parse-1.9.1.jar')
    compile files('libs/picasso-2.4.0.jar')
    compile files('libs/adobeMobileLibrary-4.11.0.jar')
    compile project(':cardview')
    compile project(':CropImage')
    compile project(':MapboxAndroidSDKNew')

    compile project(':UserVoiceSDK')
    compile 'com.google.android.gms:play-services:9.2.1'
    compile 'com.google.firebase:firebase-messaging:9.2.1'
    compile 'com.parse.bolts:bolts-android:1.+'
    compile 'com.android.support:design:23.0.1'
    compile 'com.android.support:appcompat-v7:23.0.1'
    compile 'com.android.support:recyclerview-v7:23.0.1'

    compile 'com.android.support:multidex:1.0.1'
    compile 'com.android.support:support-v13:23.0.1'
    compile('com.googlecode.json-simple:json-simple:1.1.1') {
        exclude group: 'org.hamcrest', module: 'hamcrest-core'
    }

    compile 'junit:junit:4.12'
    testCompile 'junit:junit:4.12'
    testCompile 'org.robolectric:robolectric:3.1.2'
    testCompile 'org.robolectric:shadows-multidex:3.1.2'
    testCompile 'org.robolectric:shadows-httpclient:3.1.2'

}

I am also aware this has to do with the way that I set up the project structure folder, which I have set the test and com.example.application folders underneath the src folder.

I am aware that there is a way to exclude the test file by using java { exclude 'src/test'} under the main sourceset, but I tried that and it didn't seem to help. I also tried to add compile 'org.robolectric:robolectric:3.1.2' and other robolectric libraries needed, but it's gotten too bothersome and now I need to set this project up properly to where I can achieve this desirable effect.

Any input is greatly appreciated.
