Board manager error java.lang.NullPointException #10335

nicholasb2101 · 2020-06-09T22:40:30Z

I am unable to properly add new boards under the board manager which states java.lang.NullPointException in red along the bottom of the window and outputs this:

I am running Arduino 1.8.11 and have tried re-installing different versions. I was using the IDE this morning and just went to use it again and now I am getting this issue.

Edit: Tested this out on my laptop also which hasn't been updated (currently running 1.8.10) and it also has this error occurring.

The text was updated successfully, but these errors were encountered:

nicholasb2101 · 2020-06-09T23:51:48Z

Sounds like this is an error on the board's manager package updating when loading.

KCole313 · 2020-06-10T00:05:39Z

Same root cause as #10331, #10332, and #10333.

TheWebMachine · 2020-06-10T01:05:17Z

While it was working perfectly on TWO systems as recently as 13 hours ago, neither are working now. Boards Manager AND Library Manager give the same exact error after trying to obtain updates. A bad json file released today on arduino.cc, perhaps?

mjfos2r · 2020-06-10T01:27:45Z

same

mjs513 · 2020-06-10T02:03:55Z

Think I have a related issue where the IDE fails to start and dies on loading packages. I just posted on the forum: https://forum.arduino.cc/index.php?topic=671157.new#new

QUOTE:
Well here is another of the same issue.

I deleted the Arduino15 the IDE 1.8.12 would then start and when I closed it and tried to reopen the IDE would not start. Seems to be dying at loading package manager. This just started today.

Running Arduino_debug I get the following:

mjs513, I have the same history and same issue !

Gustavomurta · 2020-06-10T02:25:48Z

I think is some bad package. I'm reading application log to see if something is wrong.

Gustavomurta · 2020-06-10T03:17:29Z

I think I found the problem!
The file is corrupted = package_index at
C:\Users\XXX\AppData\Local\Arduino15
I rename this file and Arduino now running.
But I lose all packages.

Then I added ESP32 package again. And the problem returns to lock IDE.

chefer · 2020-06-10T03:28:29Z

Apparently it works. Night construction.

Gustavomurta · 2020-06-10T03:29:44Z

Cheffer, please add ESP32 Package an test the IDE.

chefer · 2020-06-10T03:36:59Z

Gustavomurta,
I deleted C: \ Users \ xxxx \ AppData \ Local \ Arduino15
and uninstalled C: \ Program Files (x86) \ Arduino

I downloaded
https://www.arduino.cc/download.php?f=/arduino-nightly-windows.zip

Then added ESP8266.
I loaded the code and everything worked again.

Gustavomurta · 2020-06-10T03:40:31Z

Please, update the Boards. Then the IDE will crash.
The problem will occur after update of Boards Manager.

I think something is wrong here:

The file is corrupted = package_index at

You can delete this file to run IDE, but after updating of Board Manger it will crash again.
We must wait for the solution from Arduino.

I agree 100% with the above post as I am experiencing the same same issues after trying to use board manager. Board Manager fails with index issues with the base packages.

++1 here on my end. Spent hours reinstalling, fixing, hacking. Glad found this thread to confirm my thinking.

Same here.
Short Term Solution: The hourly build version works fine:

We had a problem on our package_index.json that caused the error and prevented the IDE to start.
Now the package_index has been fixed, but to recover a working installation you must delete once again the package_index.json with the cache folder and restart the IDE as usual.

Windows:

remove file C:\Users\YourUsername\AppData\Local\Arduino15\package_index.json
remove folder C:\Users\YourUsername\AppData\Local\Arduino15\cache

Mac:

remove file /Users/YourUsername/Library/Arduino15/package_index.json
remove folder /Users/YourUsername/Library/Arduino15/cache

Linux:

remove file /home/YourUsername/.arduino15/package_index.json
remove folder /home/YourUsername/.arduino15/cache

Please note that the problem that prevents the IDE to start has already been fixed and it's ready for the next release, that's the reason why the Nightly/Beta Builds are not affected, and also the reason why we did not detect this problem earlier, sorry about that!

cant find these on ubuntu 20.04:

Linux:

remove file /home/YourUsername/.arduino15/package_index.json
remove folder /home/YourUsername/.arduino15/cache

any clue where to look?

You likely installed the snap version. In this case, look here:

~/snap/arduino/current/.arduino15/
(~ is your home directory; usually /home/{username}/)
