Changes in this PR

Describe the new behavior from this PR, and why it's needed
When pulling the repository to a windows machine git will automatically convert the files line ending to windows format (CRLF). This however is not compatible with Gradle. To prevent git from automatically changing these when the repository is pulled, the .gitattribute file has been updated and the below lines have been added.

*.gradle eol=lf
*.java eol=lf
*.groovy eol=lf
spring.factories eol=lf
*.sh eol=lf
