Here command have constructed {{-annotation}} as an argument, but if look at log trace {{-annots}} should be argument name. If i manually change command with {{-annots}} and try to run from windows command prompt it does able to convert pdf2xml.

I have checked code here and -annotation is as an argument, which is not configurable to change it to {{-annots}}, https://github.com/kermitt2/grobid/blob/master/grobid-core/src/main/java/org/grobid/core/document/DocumentSource.java#L81

Can you please suggest workaround or possible solution here ?

@vishnudas-raveendran grobid is not supported to work on Windows. Unfortunately three platforms are too many for us, I recommend you to run it using docker.

See some more information: https://grobid.readthedocs.io/en/latest/Troubleshooting/#windows-related-issues

Hi @lfoppiano , I cloned the latest Grobid today (v0.6.1). Faced with PDF to XML conversion error. Attaching grobid-service.log and console.log. When running from cloud-miner service it is working fine.

I need to run it locally. Grobid-service.log file: grobid-service.log

Console log on running batch from GrobidMain

Screenshot of running as service:

The result is same with PDF file from any source.

Let me know, if you need anymore info
