jcabi-maven-slf4j – Maven Log binding for SLF4J

Maven Log binding for SLF4J

Maven Log to SLF4J binding is implemented with StaticLoggerBinder singleton. This is how you use it in your Maven plugin:

import com.jcabi.log.Logger;
import org.apache.maven.plugin.AbstractMojo;
import org.slf4j.impl.StaticLoggerBinder;
public class MyMojo extends AbstractMojo {
  @Override
  public void execute() {
    StaticLoggerBinder.getSingleton().setMavenLog(this.getLog());
    // ... later ...
    Logger.info(this, "hello, world!");
    // and you can still use the usual logging mechanism
    this.getLog().info("hello again");
  }
}

The Logger.info() call will go to Maven Log through SLF4J.

Since 0.7.12 log stream is forwarded to SystemStreamLog if StaticLoggerBinder.setMavenLog() is not called. In earlier versions a runtime exception was thrown.

The only dependency you need (you can also download jcabi-maven-slf4j-0.12.2.jar and add it to the classpath):

<dependency>
  <groupId>com.jcabi</groupId>
