Error scanning entry META-INF/versions/9/org/apache/logging/log4j/util/StackLocator.class with jetty and log4j 2.9.1?
提问by Koray Tugay
This is the directory layout I have in my maven project:
这是我在 Maven 项目中的目录布局：
.
├── pom.xml
└── src
└── main
├── java
│?? └── biz
│?? └── tugay
│?? └── web
│?? └── servlet
│?? └── MainServlet.java
├── resources
│?? └── log4j.properties
└── webapp
└── WEB-INF
└── web.xml
pom.xml relavent parts as follows:
pom.xml 相关部分如下：
</dependencies>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>${log4j.version}</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-jcl</artifactId>
<version>${log4j.version}</version>
<scope>runtime</scope>
</dependency>
</dependencies>
<build>
<finalName>bare-webapp</finalName>
<plugins>
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>9.2.1.v20140609</version>
</plugin>
</plugins>
</build>
<properties>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<log4j.version>2.8.2</log4j.version>
</properties>
And here is my web.xml
这是我的 web.xml
<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>
and finally this is what log4j.properties look like:
最后这就是 log4j.properties 的样子：
# 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
So currently everything runs fine (I start jetty with: mvn jetty:start) and when I visit "/" I see in console:
所以目前一切运行良好（我用：mvn jetty:start 启动码头），当我访问“/”时，我在控制台中看到：
20:38:09.433 [qtp1503674351-26] ERROR biz.tugay.web.servlet.MainServlet - Serving request!
This is all fine..
这一切都好..
<log4j.version>2.9.1</log4j.version>
after jetty:startI get:
码头后：开始我得到：

How can I make jetty work with log4j 2.9.1? Is there a problem in my configuration or is this a bug in jetty or log4j?
如何使码头与 log4j 2.9.1 一起工作？我的配置是否有问题，或者这是 jetty 或 log4j 中的错误？
回答by Andreas
log4j 2.9 and later are multi-release jarsfor Java 9.
log4j 2.9 及更高版本是Java 9 的多版本 jar。
Your Jetty version don't support that. Either upgrade Jetty to a Java 9 compatible version, or use log4j 2.8.x.
您的 Jetty 版本不支持。将 Jetty 升级到 Java 9 兼容版本，或使用 log4j 2.8.x。
See Jetty issue #1797: JEP 238 - Multi-Release JAR files break bytecode scanning.

The following error occurred: com.ibm.ws.metadata.annotations.AnnotationException: Annotation processing failed for class: META-INF/versions/9/module-info.class
发生以下错误：com.ibm.ws.metadata.annotations.AnnotationException: Annotation processing failed for class: META-INF/versions/9/module-info.class
Above error will be encountered in WAS 9, when we try deploying and undeploying multiple applications too many times. The server becomes malfunctioning.
在WAS 9中，当我们尝试多次部署和取消部署多个应用程序时，就会遇到上述错误。服务器出现故障。
When I encountered this, I uninstalled all the applications in the server. And rebooted 2-3 times. Once the server is rebooted, I tried to deploy it again and the application worked as expected.
当我遇到这个时，我卸载了服务器中的所有应用程序。并重启2-3次。服务器重新启动后，我尝试再次部署它，应用程序按预期工作。
