Add documentation about what is the correct order of import packages

[manueljordan]

I want to try do some commits into Spring Security, I created a Test class and I got the following:

./gradlew :spring-security-config:build -x test

> Task :spring-security-config:checkstyleTest
   --- --- See the HTML image shown below --- ---

> Task :spring-security-config:checkstyleTest FAILED

FAILURE: Build failed with an exception.

BUILD FAILED in 2m 26s

The errors are the following:

From above practically all are quick to fix, but about

• Wrong order for 'org.apache.commons.logging.Log' import.

In the current README.adoc content, there is no mention about the order of import packages, so:

• what must be the correct order?. Where is that list?

I am sharing the following that I configured long time ago for Spring Integration

Hello

I fixed this situation with the following (for only one test class with some set of import packages - perhaps it would fail in other scenarios where other import packages are imported and are not related in the list shown below):

IMHO - It should added in the documentation

It would be good to document the order. The current setup is quite hard to find.

Let me clone the project and do some experiments and then I will improve that class and javadoc, mostly the latter.
And then I am going to create some java and test classes in the samples directory

It would be for the next week (if all go well).

Thanks for your understanding
