私はmaven log4j2から実行すると動作しているアプリケーションを持っています:
mvn exec:Java -Dexec.args=...
しかし、jarをスタンドアロンアプリケーションとして実行すると、エラーが表示されます。
Java -jar
ログ:

このエラーは理解できません。 log4j2構成ファイルが見つからないだけでなく、おそらく構成ファイルにある何らかの形式について文句を言うことを示しています
私の構成は次のとおりです。
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="off">
<Appenders>
<Console name="console" target="SYSTEM_OUT">
<PatternLayout pattern="%d [%t] %-5p - %-26.26c{1} - %m\n" />
</Console>
</Appenders>
<Loggers>
<Root level="info">
<AppenderRef ref="console" />
</Root>
<Logger name="my.package" level="DEBUG" />
</Loggers>
</Configuration>
また、jarファイルのルートディレクトリにあります。
更新
jarはmaven shadeプラグインによって作成されます:
<groupId>org.Apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
必要なすべてのライブラリ(約23 MB)が含まれているため、このjarを実行するときは引数を指定するだけです
わかった、私はこれを見つけた issue この問題について。
つまり、アプリケーションクラスがmaven shadeプラグインを使用してuber jarにパッケージ化されている場合に問題が発生します。 log4j2
バージョン 2.8.1
修正はまだ保留中です。推奨される回避策は、Mavenを更新することですpom.xml
次のようなシェードプラグインの追加の構成設定:

@hudiによる回答に加えて、変換用のプラグイン内に依存関係を追加する必要があります。
