Flavor error duplicate classes after updating to Gradle 3.0

After updating Android Studio and Gradle to version 3.0 I can't build my app with 3 flavors (dbg, production, and nostore production)
In java/src folder of each flavor source set (exclude main) I have class Flavors.class with some methods specified for this source set.
But when I try to Run or Build app I have error: Error:(9, 8) error: duplicate class: my.app.namespace.Flavors.
Also I add to Gradle variant dimensions flavorDimensions "dbg", "prod","nostore" and add dimension value to each flavor section.
This is how its look:

android{
   compileSdkVersion 24
   buildToolsVersion '26.0.2'
   ...
   flavorDimensions "dbg", "prod","nostore"
   productFlavors {

    dbg{
        ndk {
            abiFilters "armeabi", "x86"
        }
        dimension "dbg"
    }

    production{
        ndk {
            abiFilters "armeabi", "x86"
        }
        dimension "prod"
    }

    nostoreprod {
        ndk {
            abiFilters "armeabi", "x86"
        }
        dimension "nostore"
    }
  }     
}

I don't understand what's wrong, this code look like in samples on https://developer.android.com/studio/build/build-variants.html.
And one thing, on Build Variants panel now I have only 2 variants: dbgProductionNostoreprodDebug and dbgProductionNostoreprodRelease but in previous version of AS and Gradle I had different variants for each flavor on this panel. (Look like AStudio try to make single build with all variants in same time or what?)

The configuration you pasted will correctly produce only 2 variants, because each of the 3 dimension only has 1 flavor and then there are 2 implicit build types (release and debug):

+-----+------------+-------------+-----------+---------------------------------+
| dbg |    prod    |   nostore   | buildType |        resulting variant        |
+-----+------------+-------------+-----------+---------------------------------+
| dbg | production | nostoreprod | debug     | dbgProductionNostoreprodDebug   |
| dbg | production | nostoreprod | release   | dbgProductionNostoreprodRelease |
+-----+------------+-------------+-----------+---------------------------------+

What you probably wanted is 1 flavor dimension with 3 flavors instead:

+-----------------+-----------+--------------------+
| myDimensionName | buildType | resulting variant  |
+-----------------+-----------+--------------------+
| dbg             | debug     | dbgDebug           |
| dbg             | release   | dbgRelease         |
| production      | debug     | prodDebug          |
| production      | release   | prodRelease        |
| nostoreprod     | debug     | nostoreprodDebug   |
| nostoreprod     | release   | nostoreprodRelease |
+-----------------+-----------+--------------------+

Which could look like this:

...
flavorDimensions "myDimensionName"
productFlavors {

dbg{
    ndk {
        abiFilters "armeabi", "x86"
    }
    dimension "myDimensionName"
}

production{
    ndk {
        abiFilters "armeabi", "x86"
    }
    dimension "myDimensionName"
}

nostoreprod {
    ndk {
        abiFilters "armeabi", "x86"
    }
    dimension "myDimensionName"
}
