3. Other information (e.g. detailed explanation, logs, related issues, suggestions how to fix, etc):

The rocketmq-tools's effective-pom shows that the org.slf4j:slf4-api:1.7.7 only in dependencyManagent（inherited from parent pom），not in dependencies，this dependency should explicit specified like the logging submodule

Sorry for my fault, my local repository ch.qos.logback:logback-classic:1.0.13 pom is damaged(No any dependecy, while the same pom from central repo has slf4j-api dependency).

Close it!
