Invalid Library Found

Hardware:

Board: ESP32 WROOM
Core Installation/update date: 21/03/2018
IDE name: Arduino IDE 1.8.5
Flash Frequency: 40Mhz
Upload Speed: 115200

Description:

When attempting to add the Arduino-esp32 library to the Arduino libraries folder and selecting the board in the board's manager. I receive this error multiple times:

Invalid library found in C:\Users\asus\Documents\Arduino\libraries\hardware: C:\Users\asus\Documents\Arduino\libraries\hardware

I have so far re-installed Arduino, reinstalled an earlier version of Arduino. I have followed the guidelines suggested in issues #766, #793, #770. I used this guide to install the library https://learn.sparkfun.com/tutorials/esp32-thing-hookup-guide . Using commit 3a4ec66

Thanks in advance for any help.

Sketch:

//Change the code below by your sketch
#include <Arduino.h>

void setup() {
}

void loop() {
}

Debug Messages:

Enable Core debug level: Debug on tools menu of Arduino IDE, then put the serial output here

arduino-esp32 is not a library. It goes directly in the <arduino>/hardware/espressif/ directory (hardware/ should already exist).

This is the file structure that I have put the esp32 folder in

Are you talking Arduino folder in program files (x86)?

@strachaldrat no, with your example

This Pc > Documents > Arduino > hardware > espressif

Chuck.

Ok thanks
