maven: 给jar包指定 定制的 logback.xml

This example shows you how to use Maven to exclude the logback.xml file from the final Jar file.

Note
Please, DO NOT include the logback.xml into the final Jar file, it will cause multiple logback.xml files in the classpath, if someone is using your Jar, you may override other’s logging configurations accidentally.

pom.xml

<project>
  <build>
    <plugins>
	<!-- Make this jar executable -->
	<plugin>
		<groupId>org.apache.maven.plugins</groupId>
		<artifactId>maven-jar-plugin</artifactId>
		<configuration>
		        <!-- exclude logback.xml -->
			<excludes>
				<exclude>**/logback.xml</exclude>
			</excludes>
			<archive>
			   <manifest>
			     <mainClass>com.mkyong.core.crawler.App</mainClass>
		           </manifest>
			</archive>
		</configuration>
	</plugin>
   </plugins>
  </build>

</project>

Copy

You can still pass in your custom logback.xml file via logback.configurationFile system property like this

$ java -jar -Dlogback.configurationFile=/full_path/logback.xml final.jar
