I followed the instructions at https://www.ibm.com/developerworks/community/blogs/wasdev/entry/download_nd_eap?lang=en, and ran the command java -jar wlp- nd-r unti me-8 .5.n ext. beta .ja r as instructed from cygwin.
However it does not work, giving the error:
First question is how do I get the unpacker to work under cygwin? We do not have access to the cmd prompt directly.
Second, why is Liberty distributed like this anyway, if it's just unzipping it can't it be shipped as a zip rather than a self extracting jar?
