Error using wyBuild from command line

Hey,

I create my wyyBuild from command line using the following commands:

First I add a new version usingwybuild.cmd.exe data.wyp -add="NewVersion.xml"

I build the wyUpdate usingwybuild.cmd.exe data.wyp /bwu

Finally I build the updates and server files and upload them usingwybuild.cmd.exe data.wyp /bu /upload -vs="x"

where x is the version number of the previous version. This procedure has worked for a long time without problems (the whole process is automated). But now the last command gives me the following output:

wyBuild Commandline Builder v2.6.18.4

Building updates[Error]: Error occurred while building the files: Error building the server file "data.wys"

I don't know what's wrong here, is there a log file where I can get more information?

Thanks,Wolfgang

It works if I invoke the command manually from command line (just tried it). In the normal workflow the command is executed via a webservice. Could it be an access right problem?

Could it be an access right problem?

That's what it is. Make sure the folder being written to by wyBuild is able to be written to by whichever user is invoking wyBuild.

Yes, that's what it is. Somehow the access rights got messed up. Works now. Thanks for your help Wyatt!
