  = Similar but different
  
  Each Spring module is slightly different from others in terms of team size, number of issues, etc. Therefore, each project is managed slightly different. You will notice that this document is very similar to the https://github.com/spring-projects/spring-framework/wiki/Contributor-guidelines[Spring Framework Contributor guidelines]. However, there are some subtle differences between the two documents, so please be sure to read this document thoroughly.
  
  = Importing into IDE
  
  The following provides information on setting up a development environment that can run the sample in https://www.springsource.org/sts[Spring Tool Suite 3.6.0+]. Other IDE's should work using Gradle's IDE support, but have not been tested.
  
  * IDE Setup
  ** Install Spring Tool Suite 3.6.0+
  ** You will need the following plugins installed (can be found on the Extensions Page)
  *** Gradle Eclipse
  *** Groovy Eclipse
  * Importing the project into Spring Tool Suite
  ** File -> Import… -> Gradle Project
  
  As of new versions of Spring Tool Suite, you might need to install Groovy Eclipse pointing directly to the updated plugin location. To install Groovy Eclipse on Spring Tool Suite based on Eclipse Oxigen you must do the following steps:
  
  Help -> Install New Software… -> Add the following URL into _Work with_ field:
  https://dist.springsource.org/snapshot/GRECLIPSE/e4.7/[https://dist.springsource.org/snapshot/GRECLIPSE/e4.7/]
