Java no class def found error while installing elasticsearch?

I followed these steps on https://github.com/karmi/tire to install
elasticsearch

curl -k -L -o elasticsearch-0.17.6.tar.gz
http://github.com/downloads/elasticsearch/elasticsearch/elasticsearch-0.17.6.tar.gz

tar -zxvf elasticsearch-0.17.6.tar.gz

./elasticsearch-0.17.6/bin/elasticsearch -f

I am running this on MinGW on windows 7, and most of the process went
smoothly.

However, as I try to start the server with ./elasticsearch-0.17.6/bin/
elasticsearch -f I get a java no class def found error:

$ ./elasticsearch-0.17.6/bin/elasticsearch
Exception in thread "main" java.lang.NoClassDefFoundError: org/
elasticsearch/bootstrap/ElasticSearch

Could not find the main class:

What gives?

I am not familiar with the Ruby/Tire client, but if it is working via
HTTP, there should be no reason why you would not be able to work with
the latest ES version (0.18.6). Try installing the latest version and
see if you get the same error.

https://github.com/downloads/elasticsearch/elasticsearch/elasticsearch-0.18.6.tar.gz

Also, I am not sure if the -f flag works on Windows, but it still
would not be the cause of NoClassDefFoundError.

It might be a problem wiht MinGW and installing elasticsearch in a path
with spaces. Frist, try and see if you still get it with the latest
elasticsearch (0.18.6). If it still happens, they some path variables
should probably be quoted (which one does MinGW calls, the
elasticsearch.bat one or the elasticsearch one?).

Yeah It did turn out to be a MinGW problem. I had to use windows style
paths instead of unix style paths for classpath and it is working now.

Thanks guys
