Hello! When running DITA-OT transformation scenarios in oxygen, some oxygen specific jar's are automatically added to the command. One of them, oxygen.jar is putting some requirements on what versions of other libraries can be used. This causes issues when running an personal version of DITA-OT if I want to use the libraries included with DITA-OT. Oxygen 10.3: xercexImpl.jar needs to be of version 2.9.1. Using xerces 2.9.0 (the version that comes with DITA-OT 1.5M20) throws the error: java.lang.NoClassDefFoundError: org/apache/xerces/util/ XMLLocatorWrapper Copying the command to shell and removing the lib include for oxygen.jar makes it work with the older version of xercesImpl.jar. Oxygen 11 Beta: oxygen.jar causes external DITA-OT to fail on (I haven't had time to track down this problem any further.): gen-list-without-flagging: [pipeline] Using XERCES. [pipeline] java.lang.RuntimeException: Cannot read edition.properties file [pipeline] at net.sf.saxon.Configuration.<clinit>(Unknown Source) Request: A possibility to disable oxygen.jar / author.jar, etc. from the DITA-OT transformation call.
