Error when i create javaDoc, cannot read Input length = 1

What's the full path of your project? Does it have any non-ascii characters?

The original path is this
D:\DAM\1º DAM\Módulos\Programación\T6 - Programación Orientada a objetos\Ejercicios\Libro\Libro\src

I need to change the project to other path?

Yes, try moving to another path without special characters.

Nice!!
That work
Thanks.

I am having similar issue, path to my project is "D:\ownCloud\pjv\arimma", to me it seems, that idea is unable to create javadoc_args file in "C:\Temp\javadoc_args".

In idea it doesn't look like link and in file explorer i can't see any file named javadoc_args. Can someone help?

Hi Matěj Martínek

Does it work if you change the output directory in the 'Generate Javadoc' settings to something else, e.g. C:\JavaDoc?

If it doesn't, please paste the entire output copied from the console after running 'Generate Javadoc'.

When i am using JDK 19 the output is always same, even whe i try to switch to another output dirr, before i was generating it into "D:\javadoc", but if i try to switch to JDK17, it looks to work flawlessly.

the output for JDK19 is:

"C:\Program Files\Java\jdk-19\bin\javadoc.exe" -public -splitindex -d C:\javadoc @C:\Temp\javadoc_args
error: cannot read Input length = 1

"javadoc" finished with exit code 1

Does it work if you copy the actual command from the output and execute it from the command line outside of IntelliJ IDEA?

See if it helps to add -Dfile.encoding=UTF-8 into Help | Edit Custom VM Options and restart the IDE.

When I try to run it in CMD i get this:

C:\Users\Matěj Martínek>"C:\Program Files\Java\jdk-19\bin\javadoc.exe" -public -splitindex -d D:\javadoc @C:\Temp\javadoc_args
error: cannot read C:\Temp\javadoc_args

I also tried adding "-Dfile.encoding=UTF-8 " to Custome VM options, closing IDEA and reopening it, and it still does the same thing

It seems to be a java-Windows, but we're currently trying to check the behaviour of different jdk with IDEA on Windows with a similar case to see if there can be some workaround.
Could you please tell if the behaviour is different for you if use jdk 20?

To me it seems that, it is doing same thing as JDK19

"C:\Program Files\Java\jdk-20\bin\javadoc.exe" -private -splitindex -d D:\ownCloud\pjv\arimma\Arimma_GUI\javadoc @C:\Temp\javadoc_args
error: cannot read Input length = 1

"javadoc" finished with exit code 1
