Null Pointer Exception with no AVR Core installed

[NicoHood]

Also see: https://bugs.archlinux.org/task/67452

The Arduino IDE should handle the case when no avr core is installed. I remember that worked before, so it must be a problem of some newer versions? Since not everybody wants to use the IDE with AVR we should not rely on it. Especially on archlinux I left the choice to the user to either use the upstream arduino avr core or the archlinux avr core.

The issue still exists and archlinux users open bug reports/email me over and over again about this issue. I guess it is quite easy to fix, can you please have a look at this again?

I tried a light_bundle build and the IDE seems to start just fine:

did you have a way to reproduce the issue? maybe it's has been fixed after 1.8.13?

Hey @cmaglie thanks for picking this up! :)

We are also using a light bundle:
https://github.com/archlinux/svntogit-community/blob/packages/arduino/trunk/PKGBUILD

It is not fixed in the recent release, as users still reported the issue. You can reproduce this on a fresh archlinux install. The user folder must not have any arduino related content (like the avr boards) and the package itself should also not ship the arduino avr boards.

if I build a light bundle from the tag 1.8.13 I got this error:

     [exec] java.lang.NullPointerException
     [exec] 	at processing.app.Base.rebuildProgrammerMenu(Base.java:1705)
     [exec] 	at processing.app.Base.<init>(Base.java:286)
     [exec] 	at processing.app.Base.main(Base.java:150)

If I build from master the IDE starts cleanly, so I assume it was fixed in a way or another. Is the error above that are you experiencing?

If not, may you send me a stack trace or something else to debug it? I'm having trouble reproducing it on the master branch.

That is the error I get:

$ arduino
Picked up JAVA_TOOL_OPTIONS: 
Set log4j store directory /home/user/.arduino15
java.lang.NullPointerException

	at processing.app.Base.<init>(Base.java:286)
	at processing.app.Base.main(Base.java:150)

Maybe it got fixed, we will see with 1.8.14. When will it be released?

Offtopic: Can you also have a look at arduino/arduino-cli#1265 please?

It was fixed with 1.8.14, thanks a lot!
