How to: SLF4J with multiple bindings in a GWT Maven multi-module project? - gwt

Question

I have a GWT multi-module Maven project.
Layout:
pom.xml
client-module //client side: contains some base classes. I use JDK's java.util.log so that it logs on Firebug's console
server-module //server side: extends some code from client-module (so it uses JUL) for common behaviour. I use log4j
client-module is shared code.
I want to use SLF4J globally but it seems that I cannot use multiple bindings (multiple bindings per project, single binding per maven module).
I would agree, but I want to use a specific SLF4J binding per maven module.
So in my case would be SLF4J-JDK for client-module and SLF4J-log4j for server-module.
Pieces of relevant code:
pom.xml
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.6.3</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-jdk14</artifactId>
<version>1.6.3</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.6.3</version>
</dependency>
client-module/BaseFoo.java
public abstract class BaseFoo {
private static final Logger logger = LoggerFactory.getLogger(BaseFoo.class.getName());
// ... interesting stuff
}
server-module/Foo.java
public class Foo extends BaseFoo {
private static final Logger logger = LoggerFactory.getLogger(BaseFoo.class.getName());
// ...more interesting stuff
}
I have already tried to configure according to documentation, but it doesn't work.
The problem is that SLF4J needs to be GWT ready.
The error I get:
[ERROR] Line 23: No source code is available for type org.slf4j.Logger; did you forget to inherit a required module?
What it means that GWT compiles the BaseFoo class to Javascript (that's why is it in client-module to run on client side) but fails because the classes/source code in SLF4j are not emulated.
Do you have any workarounds?
Thanks!
