FHIR build fails with NoSuchMethodError: net.sf.saxon.Configuration.newConfiguration()

问题

Following instructions at http://wiki.hl7.org/index.php?title=FHIR_Build_Process my FHIR build is failing. I modified the publish.bat to ensure it uses the correct JDK. Running it on Windows 7 64-bit machine with JDK 1.6 (also tried JDK 1.7) and both failing with same error.

Looks like some Saxon JAR hell somewhere. Any ideas?

A workaround... do a fresh build of the publisher tool jar from source.

Following instructions in the build/buildhowto.txt I was able to build the tool jar inside Eclipse, run the Publisher successfully from inside Eclipse and then export it as a fresh tool jar overwriting the one I pulled from SVN. The freshly build one then ran to completion from the command line.

Could be there's just a problem with the version of tools jar out there in SVN at the moment.

For the record I am working with Version 0.12-1953.

回答2:

You have two classes net.sf.saxon.Configuration in your classpath. One containing the method newConfiguration() and one not.

The method is probably called from Saxon-HE 9.x, and the class net.sf.saxon.Configuration is found in saxon 8.x, while the class should have been found inside Saxon-HE 9.x, where it also is, and does have this method.

So, check your dependencies to see if saxon 8.x is called, and try replacing that with Saxon-HE 9.x, then your problem is solved
