通过IntelliJ运行JavaFX应用程序时，一切都很好。加载了自定义Log4j2附加程序，并且正确解析了所有FXML。但是，当使用Maven将应用程序打包为JAR时，找不到附加程序。为了解决这个问题，日志配置XML中包含一个packages="MyApp.util"属性，它指向自定义附加程序的程序包。添加此属性后，应用程序会以XMLStreamException: ParseError开始引用FXML文件中的任意行而崩溃。

此外，无论是否包含软件包属性，运行Jar时（在Intellij中为null null），log4j2的版本都显示为Apache Log4j Core 2.12.1：
2019-11-05 10:24:38,666 JavaFX Application Thread DEBUG null null initializing configuration XmlConfiguration[location=/home/me/config/logging.xml]

我已经确保Log4j API +核心实现都与Jar文件打包在一起。 Jar中包含一个基于Log4j 1.x的内部公司库，但是我不确定这是否会引起冲突。

Log4j2 XML配置：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="trace" packages="MyApp.util">
    <Appenders>
        <Console name="Console" target="SYSTEM_ERR">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} %-5level %logger{36} - %msg%n"/>
        </Console>
        <FXAppender name="JavaFXLogger">
            <PatternLayout pattern="%d{HH:mm:ss}   %msg%n"/>
            <ThresholdFilter level="warn"/>
        </FXAppender>
    </Appenders>
    <Loggers>
        <Logger name="MyApp.data.Acquisitioner" level="info"/>
        <Root level="debug">
            <AppenderRef ref="Console"/>
            <AppenderRef ref="JavaFXLogger"/>
        </Root>
    </Loggers>
</Configuration>
