Re: [m2e-users] [Issue] Embedded maven can't find SLF4J when there's a workspace dependency 
I don't know if this worked or not, but below is the console output
running jetty:run goal on struts-module of the project you provided.

I had to enable workspace dependency resolution to make this work,
otherwise I was getting artifact resolution error for module1.

This was tested on macosx using fresh/clean m2e 1.1 installation, i.e.
without any m2e extensions.

Hope this helps.

Dear all,

I have a possible bug and I'd like to ask your help and opinion on it. T

*Assumptions:*
- The slf4j dependencies in the struts-module pom.xml are correct. I
believe they are: line 44-55 declare the dependencies and line 77 and
below tackle the commons-logging dependency.
- Running m2e 1.0.100.20110804-1717 on Indigo
- Running JDK: java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)


*Steps:*
1) Add zipped project in Eclipse. It is composed of parentA and two
modules: module1 (jar) and struts-module (war)
2) Create a run configuration for the struts-module with goal jetty-run

*Expected:*
- Runs without problems

*Actual:*
First few lines of log say:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for
further details.

*Pinpointing the issue:*
- If you remove the module1 dependency of struts-module (line 89 of the
pom) the problem disappears.
- If I switch the run configuration to use "external maven - 3.0.3"
instead of "embedded", the problem doesn't appear.


I appreciate your feedback. If you could try out the testCase, it would
be great.

Cheers,

Miguel Almeida
