[slf4j-user] log4j-over-slf4j 1.6.1 and Ant Listener

[Scott Dudley]

I've recently been testing our applications on log4j 1.6.1 and also used 
the log4j-over-slf4j bridge.

Everything has worked beautifully thus far with but one exception: one 
of the developers authored some Ant-related code which registers a listener:

Project antProj = new org.apache.tools.ant.Project();
Log4jListener log4jListener = new 
org.apache.tools.ant.listener.Log4jListener();
antProj.addBuildListener(log4jListener);

This results in the following Exception:

java.lang.NoSuchMethodError: 
org.apache.log4j.Logger.getAllAppenders()Ljava/util/Enumeration;
     at 
org.apache.tools.ant.listener.Log4jListener.<init>(Log4jListener.java:51)
     at 
com.telesoft.ant.AntTargetLauncher.executeAntTask(AntTargetLauncher.java:32)
     ...

I stubbed out this method in org/apache/log4j/Category.java and got past 
that hurdle only to encounter the following:

java.lang.NoClassDefFoundError: org/apache/log4j/helpers/NullEnumeration
     at 
org.apache.tools.ant.listener.Log4jListener.<init>(Log4jListener.java:51)
     at 
com.telesoft.ant.AntTargetLauncher.executeAntTask(AntTargetLauncher.java:32)
     ...

How does one replace log4j/Ant integration via slf4j?

Thanks.
