Question

我已经尝试过了： Mixing log4j 1.x and log4j 2 with third party libraries dependending on log4j 1.x

当我将jar文件部署到docker映像时，却收到log4j 1追加程序错误，但是在Eclipse中运行main方法时却看不到该错误。

log4j：WARN找不到记录器的附加程序（blah）。 log4j：WARN请正确初始化log4j系统。 log4j：WARN有关更多信息，请参见http://logging.apache.org/log4j/1.2/faq.html#noconfig。

这是我的依赖项

我尝试删除所有可能引用log4j 1的内容（包括log4j-1.2-api）以进行编译和测试（除了删除代码中对slf4j的引用并使用log4j api之外）均无济于事。

启动我的jar文件的命令是：

java -Dlog4j.configurationFile=$LOGGING_CFG -Ddatacollector.config.dir=$CONFIG_DIR -jar blah.jar

我已验证我的参数有效，并确保该配置在IDE中有效。我什至尝试使用Configurator.initialize（name，filePath）以编程方式加载文件。我怀疑log4j 1在我的环境中存在，我想将其清除。

感谢您的帮助。

我通过将Maven程序集插件版本更新为3.1.1解决了该问题。

       <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <!-- Needed to get the correct log4j -->
            <version>3.1.1</version>
            <executions>
                <execution>
                    <id>distrib</id>
                    <phase>package</phase>
                    <goals>
                        <goal>single</goal>

                    <configuration>
