I'm also getting the error:

System.IO.DirectoryNotFoundException: Could not find a part of the path

I either need help fixing the library issue or rolling back to the previous plug in because I have software that I have to get out and now I can't compile software that used to compile.

Update:

Now when I open my project, I get:

Build validation failed for sketch 'PROJECT': Could not find a part of the path \libraries\SPI\Scheduler'. Ide=Arduino 1.6/1.8

Here is the output per the yellow box:

What doesn't make any sense is that none of my includes are being found.  In the build validation error above, it says it can't find .../SPI/Scheduler  because that isn't where the Scheduler include is located.  In other words, I have no idea why it is looking for "Scheduler" in the SPI folder (which does exist by the way)

I use the standard (with the exception of one):

#include <SPI.h>
#include <util.h>
#include <Twitter.h>
#include <EthernetUdp2.h>
#include <EthernetServer.h>
#include <EthernetClient.h>
#include <Ethernet2.h>
#include <Dns.h>
#include <Dhcp.h>
#include <Scheduler.h>
#include <Scheduler\Queue.h>
#include <UC1701.h>
#include <Indio.h>

None of these libraries are being found (all the #include have red squiggly lines under them)

Ahhhh  progress.  Not all the way but progress:

NTC_V3_1_1_INDUSTRINO_MAIN.ino: 11:19: fatal error: Queue.h: No such file or directory
   #include <Queue.h>
   compilation terminated 

Commenting out the Queue.h include allows the deep scan to complete and then it tries to compile, which fails of course because the Queue.h include is missing.

How do I include it?

What is install url for the scheduler lib? The standard scheduler doesn't have the queue file.

In any event a short term workaround while we investigate might be to switch off "vmicro>compiler>deep search" and add the Scheduler\ back into the queue.h include.

This scheduler is a header only implementation so I just moved the header to the root src directory of the Scheduler library and got it to compile. 

I can't reproduce as is do would be useful to have a list of download locations for the libs you have used. 

The berose option wasn't on for your diangostics .txt file I am assuming you are in vs2017 or 2019. There was a change to fix folders in lib includes but that was in 1907.7.0 which is what you should have installed. It's possible the fix went out in the next release so when you get time please try the work in progress download of 1908.7.4 from the top of this board.

Thanks

That explains it but I am unsure how you managed to install 1908.05 on the 12th

If you look down the right hand side of the current gallery page you should see the version and that is was updated on 8/8/2019. What version do you see in the IDE using "tools>extensions and updates>online" or "Extensions>extensjon manager>online"?

Version

Yes, the online version is build 1908.7.0  Not sure how I got the .5 version.

And with build 1908.7.4, the #include <Scheduler/Queue.h> compiles without an error.

Thank you very much for the rapid support.  I have a short deadline and I had visions of not being able to compile for days.
