Add guava to persons1 libs.txt #110

Closed elakito closed 2 years ago

elakito commented 2 years ago

Avoid getting java.lang.NoClassDefFoundError at the sink connector in example persons1.

In some old kafka such as 2.4.1, kafka's libs folder contained a compatible guava jar. As a result, the instruction for examples persons1 didn't refer to guava. As more recent kafka releases do not contain guava, this jar must be added to the plugins folder otherwise the below error occurs.

This fixes #109
