Hi. This is in reference to issue #24 . I downloaded the project and ran a dump-based extraction. Everything went well, just faced a java issue(Had to make sure to use java1.8, used jenv for this.) before the extraction. However, I had to stop the ../run download download.10000.properties command at date page 'https://dumps.wikimedia.org/wikidatawiki/20190101/' has all files [pages-articles-multistream.xml.bz2] downloading 'https://dumps.wikimedia.org/wikidatawiki/20190101/wikidatawiki-20190101-pages-articles-multistream.xml.bz2' to '/Users/anubhavujjawal/Desktop/data/extraction-data/2018-10/wikidatawiki/20190101/wikidatawiki-20190101-pages-articles-multistream.xml.bz2' read 28.0153 MB of 58.74201 GB in 01:52 min since I didn't have the available bandwidth and space(I use a macbook air 128 GB model) to complete this. After it, I ran ../run extraction extraction.default.properties ran well. Have I messed anything up?

Hi everyone and @mgns . I tried the instructions of the dump-based-extraction here on both of the download.10000.properties and download.minimal.properties download config file and got an error "Caused by: java.lang.IllegalArgumentException: Base directory does not exist yet: \data\extraction-data\2018-10" for both.

I tried to create directories from the root with /data/extraction-data/2018-10 but still got the error.

Is there any solution to this? Thank you very much.
