3.1.2 Build# 307 Compilation Warnings
Dear Fellow OpenMeetings Developers,
We are getting seemingly harmless Maven compilation warnings in OpenMeetings
3.1.2-Snapshot, build # 307. Are these purposeful? Will these be removed
in RC3?
For example, SLF4j Java logging API is missing in the artifact. Hence, the
underlying logging backend may not be determined at runtime if the desired
binding to the classpath and may be the standard Sun Java logging package
java.util.logging, log4j, logback, or tinylog are added by any advanced
users of OpenMeetings.
The following files cannot be found in the artefact during scanning step of
compilation.
slf4j-api-1.7.21.jar
logback-classic-1.1.7.jar
logback-core-1.1.7.jar
red5-server-common-1.0.8-M6.jar
xmpcore-5.1.2.jar
derbyLocale_cs.jar
derbyLocale_de_DE.jar
and many more.

Re: 3.1.2 Build# 307 Compilation Warnings
Posted by "seba.wagner@gmail.com" <se...@gmail.com>.
Hi Hemant,
the logging framework warning during compile time are maybe a but
confusing. We could do them maybe as "scope=provided" Maven dependencies.
The difficulty will be that they are available in the common-lib directory
of the Red5 Streaming Server (a version of Tomcat enhanced with the Red5
streaming components).
So yeah, I think it's kind of save to say those compile time issues only,
low impact. The important bit is that the logging framework during runtime
is correct.
It might be also that the version of slf4j in the latest Red5 release
updated, which might be the next exception in the log.
Obviously it might also only work to compile at the moment since there is a
valid fallback, so it should be looked at.
Thanks,
Sebastian
