Each application should log.
Chosen option: “Logback”, because it 1) natively implements SLF4J and 2) SLF4J offers bridging legacy APIs and thus allows to unify logging.
Positive Consequences:
Negative consequences:
Developers have to include following dependencies in their pom.xml, because the concrete logging framework should be chosen at the project executed by a user (or on a server).
Tests still require logging and thus the concrete logging framework has to be included for tests.
For easy logging, it is enough to include logback libraries at WEB-INF/lib.
Thus, following dependency has to be included at REST services:
Any logging wrapper has also has to be included at “user-facing” ends (CLI or WAR). Note that it cannot be included at libraries, because it leads to an infinite loop.
Legacy/old libraries depending on a certain logging framework have to be loaded with an exclusion of the logging framework.
The documentation of Winery has to state that slf4j was chosen and that the logging has to be configured accordingly.
