エントリMETA-INF / versions / 9 / org / Apache / logging / log4j / util / StackLocator.classをjettyおよびlog4j 2.9.1でスキャン中にエラーが発生しましたか？

これは、私のMavenプロジェクトにあるディレクトリレイアウトです。

pom.xmlの関連部分は次のとおりです。

</dependencies>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>

そして、ここに私のweb.xmlがあります

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                             http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
</web-app>

最後に、これがlog4j.propertiesの外観です。

# suppress inspection "UnusedProperty" for whole file

# logger level configurations
log4j.rootLogger=ALL, console

# configuration for console outputs
log4j.appender.console=org.Apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.Apache.log4j.PatternLayout
log4j.appender.console.layout.conversionPattern=[%t] %-5p %c - %m%n

そのため、現在はすべて正常に動作し（mvn jetty：startでjettyを起動します）、「/」にアクセスするとコンソールに表示されます。

20:38:09.433 [qtp1503674351-26] ERROR biz.tugay.web.servlet.MainServlet - Serving request!

これはすべて大丈夫です。

<log4j.version>2.9.1</log4j.version>

後jetty：start私は得る：

Log4j 2.9.1でjettyを動作させるにはどうすればよいですか？私の構成に問題はありますか、これはjettyまたはlog4jのバグですか？

log4j 2.9以降は multi-release jars for Java 9。

Jettyバージョンではサポートされていません。 JettyをJava 9互換バージョンにアップグレードするか、log4j 2.8.xを使用します。

Jetty issue＃1797： JEP 238-Multi-Release JARファイルがバイトコードスキャンを中断する を参照してください。

次のエラーが発生しました：com.ibm.ws.metadata.annotations.AnnotationException：クラスの注釈処理が失敗しました：META-INF/versions/9/module-info.class

WAS 9では、複数のアプリケーションのデプロイとアンデプロイを何度も試行すると、上記のエラーが発生します。サーバーが誤動作します。

これに遭遇したとき、サーバー内のすべてのアプリケーションをアンインストールしました。そして、2〜3回再起動しました。サーバーを再起動したら、もう一度デプロイを試みましたが、アプリケーションは期待どおりに機能しました。
