Subject RE: How to accumulate a list of files for pmd instead of running pmd on each one
Date Thu, 08 Nov 2007 21:23:49 GMT
I discovered that I needed to try the XSLT solution, because for some of
my largish XML files, xmltask seems to die with an OutOfMemory error.
These files aren't really that large, but they result in 40-50
occurrences of the target string.

It was pretty quick to implement, and in the directory with my build
script, I tested it, and it worked fine.

However, I then went to another directory built with Maven, where my
build script is called with "ant:ant", and which was previously working
with the xmltask solution (except for the occassional OOM), and that
fails with:

	Provider for javax.xml.transform.TransformerFactory cannot be
found

I've googled for this, and they seem to say to copy xalan.jar to my
$ANT_HOME/lib.  I already have weblogic.jar and xml-apis.jar in there,
and I don't understand why it would directly from ant in the directory
with the build script, but fail with this error from a different
directory called from maven.
