Hi all,

The typical pattern with SLF4J is to depend only on org.slf4j:slf4j-api at
compile time, and then add an implementation binding at runtime. For SLF4J
1.6+, you don't even need an implementation at runtime; it will default to
no-op with only a single one-line warning. You have to be careful though:
it's best to add the implementation binding only for end-user application
components (i.e., components not intended for reuse), and/or add the
dependency non-transitively using test or optional scope; see:

http://slf4j.org/faq.html#maven2

Anyway, I know that's a tangent from the original topic. It seems the OP
doesn't care about SLF4J; it's just a transitive dependency which should
get pulled in.

org/slf4j/LoggerFactory

Personally, I cannot reproduce this problem on my OS X 10.9 system. The
exact POM and Java source posted works for me from both the command line
and using IntelliJ IDEA 12.1.6 downloaded today.

So I agree with Wayne to start double-checking your assumptions. See if
"mvn" works on the command line, "mvn dependency:tree" or "dependency:list"
as suggested by others, maybe try in NetBeans and/or Eclipse... and if your
IntelliJ is old try upgrading it and reimporting the project from scratch.

Regards,
Curtis

At this point (with the dependency specifically declared in the pom),
you have to start questioning everything:
1. are you sure that's the right dependency declaration and version?
sometimes projects "move" and start producing new versions under a
different groupId.
2. are you sure org.slf4j.LoggerFactory is supposed to be in that jar
with that version?
3. go into .m2 and find the slf4j-api-1.7.5.jar file, open it up with
a zip tool, confirm it is a real jar (zip) and not HTML error message
4. also confirm it has org.slf4j.LoggerFactory inside
5. consider if you really want the API or an implementation package
for runtime use

To be clear, Russell is asking if you "installed Maven using apt-get
rather than downloading the tarball from the Maven website and
manually installing it."

It is true that we see "odd" problems on this list from time to time
from people who have installed a package OTHER than the one hosted on
maven.apache.org.

Did you by any chance install using apt-get? I've seen a number of cases where 
doing so leads to errors like this. Try installing manually from the website.

strange thing I observed is when I went on the command line and invoke mvn
compile , it failed with

~/M101J/src/main/java/com/tengen/HelloWorldSparkStyle.java:[19,10] error:
annotations are not supported in -source 1.3

made me think what if I generated the project from intellij - this time it
worked. I had previously generated the project directly on command line and
imported it into intelliJ and that seem to be the reason why it was not
working well.

thank you all for your pointers. this one stumps me.

Re: Maven - slf4j noclassdeffound error

[Seenu]

It is referenced by spark core

I can see slf4j-API getting pulled by the project in IntelliJ 

I also tried including the dependency in the Pom.xml. 

The noclassdeffound is still showing.

Re: Maven - slf4j noclassdeffound error

[Thomas Broyer]

None of the transitive dependencies of spark are in the classpath. It
generally happens if the POM is "invalid".
What does "mvn dependency:tree" says? Is there any error/warning in IDEA?

Re: Maven - slf4j noclassdeffound error

I don't see any reference to slf4j in your pom or your code.  Are you
sure you posted the right thing?
