I got the following error when running this processing-java command:

```auto
processing-java --sketch="C://PDE3/max/button" --output="C://PDE3/max/button/output" --force --run

```

Running processing-java without parameters works well.  
Running the code within processing 3.3.7 works well.  
System: win10 pro, java jre 1.71 32&64bit, processing 3.3.7.

Can you help me?  
Thanks

Either work:

```nohighlight
$> processing-java --force --sketch=C:\Users\C\button --output=C:\Users\C\button\out --run
Finished.

$> processing-java --force --sketch="c:/Users/C/button" --output="c:/Users/C/button/out" --run
Finished.

```

where the button pde has an empty setup and draw.

@kfrajer  
Thanks !!!  
The problem was the double quotes.  
I change it from “ to " and all works well.

I was wrong ☹  
I solve it on windows 7 (office pc).  
On windows 10 it don’t works.  
I think should be a problem with jna and some folders permission (temporary folder?).

</div>

Partial solution:

1. create o batch file with the processing-java command
2. run this batch file as Administrator

p.s. all works well until last win 10 update

Final workaround:  
run notepad++ or Visual Studio Code as Administrator 🙂

Hello everyone,

I have a similar issue as the OP. I am trying to get **processing-java** for the command line to work on **mac osx 10.13** to run **Processing2** sketches from the terminal.

So after installing the _Tools\>Install processing-java_ in **Processing2**

when I type  
`$ processing-java`  
in the terminal i get this response:

```auto
/usr/local/bin/processing-java: line 13: /Applications/Processing.app/Contents/PlugIns/jdk1.8.0_181.jdk/Contents/Home/jre/bin/java: No such file or directory

```

This used to work fine, but now it doesn’t anymore and I am getting quite clueless about this. Does anyone know which step I should take to fix this issue.

Many thanks.

Wim

Interesting. If you

```
cd /Applications/Processing.app/Contents/

```

Are the referenced files there? Different version / path? Wrong permissions?

Hello Jeremy,

Indeed, a different version.  
I looked into that directory and this is what i found:

```auto
 /Applications/Processing.app/Contents/PlugIns/jdk1.7.0_55.jdk/Contents/Home/jre/bin/java

```

So, as far as i can tell, processing-java is looking for **jdk 1.8** instead of **1.7**?  
Do you know how to fix this?

Wim

Just a guess (!), but it seems as if you installed processing-java from Processing 3, but your Processing app is Processing 2. Maybe fully uninstall processing-java and reinstall it using Processing 2?

If not, possibly check open issues relating to that jdk specifically…

Thanks,

I removed processing-java so when I do :

```auto
$ which processing-java

```

it returns nothing.

next thing I did:

- uninstalling processing2
- reinstalling processing2
- installing processing-java by tools \> install “processing-java”

but, now when i type in terminal :

```auto
$ processing-java

```

I get this in return :

```auto
-bash: processing-java: command not found

```

Thanks,  
wim

Strange. Does anybody currently using Processing 2 have any suggestions for wimbr?
