Facing issues during spring-cloud-netflix project build

[Ahmed-A-Syed]

Hi

I was trying to run the spring-cloud-Netflix project code downloaded from https://github.com/spring-cloud/spring-cloud-netflix using maven .

When I was running command : mvn install. I was facing the below errors.

We recommend you build with ./mvnw install to make sure you have a supported version of maven.

Also, this profile should ensure that egrep isn't used on windows. Unsure why that would fail? Are you using cygwin or some other bash?

[spencergibb]

See #18 for removal of grep.
