Error building Processing from its source code

When I try to build processing using command ant run -autoproxy, after some time I get,

BUILD FAILED

I think key mesaage here is "archive is not a ZIP archive" did you check .../processing_project/processing/java/reference.zip ?

parag00991

Yes, when I open reference.zip, it says "An error occured while loading the archive".

koogs

that's only the documentation, you can comment out the build instructions in the build.xml to get around it.

https://github.com/processing/processing/blob/master/build/build.xml

lines 403 to 414 there

there's probably an ant flag to get it to ignore errors too.

koogs

also the file's right there in the script

http://download.processing.org/reference.zip

downloading that i get

> ls -l reference.zip
4422900 Feb 12 18:18 reference.zip

> md5sum reference.zip
7be4b3478efb12fc72a48dda429ff5c2 reference.zip

that unzips ok for me

Thanks @koogs, but I first deleted the file .../processing/java/reference.zip and then ran command ant run -autoproxy following command ant clean and it worked for me. Thanks for the time :)
