Checkstyle->Create Formatter-Profile in Eclipse fails with error.

[oconnelc]

With the following versions:

• Eclipse: Version: 2019-09 R (4.13.0)

• Eclipse Checkstyle Project: Eclipse Checkstyle 8.18.0.201903231603

When following the instructions at: https://github.com/iluwatar/java-design-patterns/wiki/12.-IDE-instructions on the step: "Right click java-design-patterns project in Project Explorer and choose Checkstyle - Create formatter profile" an error popup is shown that says:

"transformCheckstyle has encountered a problem. An internal error occurred during: transformCheckstyle"

Look at the Eclipse logs yielded the following stack trace:

!MESSAGE An internal error occurred during: "transformCheckstyle".

While this problem seems to be caused by: https://github.com/checkstyle/eclipse-cs/issues/107 and is not related to this project, we may want to track the issue and update the documentation to indicate that this is a known issue.
