Q:

Hudson build fails when run in browser but works from command line

I am setting up a new Hudson task (on WinXP) for a project which generates javascript files, and performs xslt transformations as part of the build process.
The ant build is failing on the XSL transformations when run from Hudson, but works fine when the same build on the same codebase (ie in Hudson's workspace) is run from the command line.
The failure message is:
line 208: Variable 'screen' is multiply defined in the same scope.
I have tried configuring Hudson to use both ant directly and to use a batch script - both fail in Hudson.
I have tried in Firefox, IE6 and Chrome and have seen the same issue.
Can anyone suggest how we can workaround this problem with Hudson?

A:

Problem solved.
Our build is actually dependent on jdk 1.4.2, and Hudson appears to run using 1.6.  When I set Hudson to run as a service, it ran as my local user, which meant that it picked up the 1.4.2 JAVA_HOME environment variable - and therefore worked.
I guess another possible solution is to configure Hudson to use 1.4.2 by default.
