de.unistuttgart.ims.coref.annotator.tools.ExportMultipleFiles does not work in 1.15.x and 2.0.0-beta4

[pagelj]

In 1.15.x, the class is not found at all.

In 2.0.0-beta4, the class is found, but I don't get any output when giving a directory as input and the following error when giving a single file as input:

In 1.14.x, it is working fine with the same commands

[nilsreiter]

For 1.15.x, I cannot reproduce the problem. The class is there and found. Which command did you use exactly?

[pagelj]

I also cannot reproduce it now... I think I might have used version 1.15 in the command while being on a different version branch in git, sorry! 1.15 works for me now

[nilsreiter]

Cool, that's the kind of issue I like :-)

[nilsreiter]

For 2.0.x, one issue could be that the file format has changed, and the Export tool only iterates over files with the new ending .ca2 oder ca2z.

For 2.0.x, one issue could be that the file format has changed, and the Export tool only iterates over files with the new ending .ca2 oder ca2z.

Is this intended behavior because the app only reads the new file format or can/should any old formats be processed by the export tool? If the former, could this issue be closed?
