Upon installing 1:1.8.7-1, it is impossible to run the application.
It gives the following exception when I try to run it from command line.


I tried removing .arduino15 directory from my user's home directory but it didn't solve the problem.

Steps to reproduce:
Update to latest, launch the Arduino application
This task depends upon

With what version of java as default?
Comment by SLP (s3lph) - Thursday, 11 October 2018, 08:46 GMT
I can reproduce this with the following Java versions:
- java-8-openjdk (extra/jdk8-openjdk)
- java-10-openjdk (extra/jdk10-openjdk)
- java-8-jdk (aur/jdk8)
Comment by SLP (s3lph) - Thursday, 11 October 2018, 08:53 GMT
I just noticed, the start script (/usr/bin/arduino) has the java-8-openjdk path hardcoded into it.
Still, I can reproduce the issue with all Java versions noted above when directly running /usr/share/arduino/arduino without a hardcoded JVM.

Seems only new installs are affected where ~/.arduino15/packages/ is empty (no boardpackages installed).

Classic NPE in
TargetPlatform targetPlatform = getTargetPlatform();
if (targetPlatform != null) {

librariesIndexer.setArchitecturePriority(getTargetPlatform().getId()); <-- CRASH

If you install arduino-avr-core it should work.

New install with arduino-avr-core installed also can't start the application.

Sorry, it worked for me. Did not spend much time, just had a brief look at the code.

I just tried copying the .arduino15 directory from another machine and the application started. Maybe this is a possibility until fixed upstream?
Comment by Matthias (seehma) - Monday, 15 October 2018, 18:23 GMT
Had the same problem and Alfie's workaround also worked for me!

I had the same problem after update my system, but installing arduino-avr-core 1.6.23-1 it was solved.
But I still have the warning

The issue still happens for me with package "arduino-1:1.8.8-1". After installing avr-core like Felipe suggested (thanks for that) it went away. The "yay -S community/arduino-avr-core" i ran to fixed it pulled: "avr-binutils-2.31.1-1 avr-gcc-8.2.0-1 avr-libc-2.0.0-3 avrdude-1:6.3-3 confuse-3.2.2-1 elfutils-0.175-1 libftdi-1.4-2 arduino-avr-core-1.6.23-1"

I have the exact same problem and installing arduino-avr-core did not solve the problem for me.
(edit) Think i solved it by removing .arduino15 directory:

$ mv .arduino15 .arduino15old

And then it worked for me.
Comment by John Stone (IronPig) - Saturday, 05 January 2019, 21:40 GMT
Installing arduino-avr-core solved it for me.
If I am not wrong arduino-avr-core installs packages necessary for the Arduino IDE to compile code, but why is it an optional dependency then?
Comment by Peter Sutton (foxxy) - Sunday, 06 January 2019, 12:51 GMT
Install arduino-avr-core fixed for me as well on a clean install. I think it should be required.
Comment by Eimantas (eimis) - Tuesday, 22 January 2019, 20:36 GMT
Yep arduino-avr-core fixed it. I agree with Peter, it should be required.

Is there any chance the maintainer could take a look at this? It's been broken for a while and should be an easy fix.
Comment by NicoHood (NicoHood) - Sunday, 03 February 2019, 22:26 GMT
I do have a look at the issue, but its an upstream bug. I've described the details here:
Comment by Alfredo Palhares (alfredopalhares) - Wednesday, 27 February 2019, 16:44 GMT
I can reproduce this bug.
Comment by Oskar Roesler (bionade24) - Thursday, 21 March 2019, 05:04 GMT
I can reproduce this bug, too. Should be fixed with the new version, package have to be updated.
Comment by NicoHood (NicoHood) - Saturday, 06 April 2019, 11:16 GMT
Updated to the latest version. Is the bug gone?
Comment by Alex Dewar (billypilgrim) - Saturday, 06 April 2019, 11:18 GMT
Unfortunately not. The program gets as far as the splash screen, then it terminates with a NullPointerException.
Comment by Josh Cox (thoth) - Wednesday, 24 April 2019, 15:31 GMT
this was not resolved for me until `sudo pacman -S arduino-avr-core` was installed. I am in the arduino-avr-core should be a dependency of arduino boat.

Comment by Frank Theile (frank-ka) - Saturday, 04 May 2019, 18:37 GMT
Installing package 'arduino-avr-code' fixed the problem with Arduino IDE for me, too. Thank you @miniskipper!

I am currently very limited in time, would someone please be so nice and check if this patch fixes the bug?
