Android Data Binding XML Error

I'm using Data Binding Library on a Android Studio Project when whenever I build, run, clean, rebuild, etc I get the following error:

 :app:processDebugResources AGPBI:

{"kind":"error","text":"Error parsing XML: duplicate attribute","sources": [{"file":"C:\\Users\\lucia.beltran\\Desktop\\Picho\\Projects\\Personal\\ improved-tribble\\ImprovedTribble\\app\\build\\intermediates\\data-binding-layout-out\\debug\\ layout\\task_list_item.xml","position":{"startLine":16}}],"original":"","tool":"AAPT"}

C:\Users\lucia.beltran\Desktop\Picho\Projects\Personal\improved-tribble\ImprovedTribble\app\build\intermediates\data-binding-layout-out\debug\layout\task_list_item.xml:17: error: Error parsing XML: duplicate 

 FAILED

FAILURE: Build failed with an exception.

* What went wrong: Execution failed for task ':app:processDebugResources'.
> com.android.ide.common.process.ProcessException: Failed to execute aapt

* Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 3.826 secs

My layout is as follows

<layout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <data>
        <variable
            name="task"
            type="com.pichardo.improvedtribble.models.Task" />
    </data>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal">

    </LinearLayout>

</layout>

And the layout of the binding file that gradle console says is like:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" android:tag="layout/task_list_item_0" xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent">

</LinearLayout>

I get which the duplicate attributes are, but I don't know why is crashing.

I read this question, but I don't have any like that on my build.gradle file.

Any suggestions?

Try to remove android:layout_width and android:layout_height="match_parent" in layout tag

<layout xmlns:android="http://schemas.android.com/apk/res/android">

    <data>
        <variable
            name="task"
            type="com.pichardo.improvedtribble.models.Task" />
    </data>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal">

    </LinearLayout>

</layout>

Here's my redacted real code:

<?xml version="1.0" encoding="utf-8"?>
<layout
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:android="http://schemas.android.com/apk/res/android"
>

    <data>
        <variable
            name="MyDTO"
            type="com.example.MyDTO"
        />
    </data>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        tools:mContext="com.example.MyActivity"
    >

All namespaces must be in outer layout tag. Any deletions did not help.
