Hi Philipp,

how about defining the folder path as external resource in the CPE 
descriptor and bind it to reader and consumer?
There is a good example for that in the UIMA manual:
http://incubator.apache.org/uima/downloads/releaseDocs/2.2.0-incubating/docs/html/references/references.html#ugr.ref.xml.cpe_descriptor.descriptor.resource_manager_configuration

Best regards
Christof
