Unable to locate javac

[smoothmango]

I just downloaded Processing 2.1.1, and when I try to run my Android sketch, I get the following error in the console: [javac] Unable to locate an executable at "/Applications/Processing.app/Contents/PlugIns/jdk1.7.0_51.jdk/Contents/Home/jre/bin/javac" (-1) If I open the Processing.app package and navigate to the mentioned folder, I find an executable called java but nothing called javac. I tried renaming java to javac but this just creates more (and different) errors.

[smoothmango]

Solution found based on comments on improperly filed issue in main Processing repo. You need to create a symbolic link in the Processing.app package to javac from your system's java installation. For me that means navigating to /Applications/Processing.app/Contents/PlugIns/jdk1.7.0_45.jdk/Contents/Home/jre/bin and running: ln -s /Library/Java/Home/bin/javac javac to create the symbolic link in Processing.app

Thanks for this! Worked a treat. I hoe there are plans to fix this issue so you don't need to use the command line to fix it. Still not resolved in 2.1.2

still get error

I solved this on Windows by copying the contents of my JDK folder to the "\java\" subfolder where I had Processing installed. Heavy handed, but it worked.

1. Copy everything in the JDK folder => D:\Program Files\Java\jdk1.6.0_45\
2. Rename the "java" subfolder where Processing is installed to something like "java_backup"
3. Make a new "java" subfolder in the Processing directory and paste the contents of the JDK there.

Just to note, if you try and update the Android SDK location in the preferences.txt file, it gets overwritten . Not sure why they have a preference setting if it is just going to get overwritten every time. Also, setting the "JAVA_HOME" variable did absolutely nothing in my case.

@jones065 i did this on MAC , and can't start processing then....

Hello all

The fix posted up above works for Mac. I re-wrote it a bit and posted it on my blog:

http://theproce55.tumblr.com/post/82883027743/fixing-android-development-in-processing-2-1-1

[oolong]

Same problem here (with Mac OSX), only a bit worse, I think, because there's no javac file anywhere on this computer. I'm guessing we need to download the 200MB-odd JDK from the Oracle site to try and sort this out? It's not a great internet connection, so I'd rather try something else. How come there's no download link for 2.0.3 on the Processing site any more?

[agoransson]

There is, it's just not linked. http://download.processing.org/processing-2.0.3-macosx.zip

[oolong]

Ah, thanks @agoransson! Already got the JDK off Oracle and symlinked that, but that didn't work - just claimed to be compiling indefinitely.

2.0.3, however, is working fine. Should I open a separate 'Please keep linking to version 2.0.3 until later versions work with Android' issue, since this seems to be much the easiest solution to this problem?
