导入org.apache.log4j无法解决

我遵循了我能找到的所有记录的步骤，即:

1)以下两个JAR文件在项目构建路径中: log4j-core-2.6.2.jar和log4j-api 2.6.2.2.jar

2)上面的两个JAR文件位于以下文件夹中: C:\ eclipse \ apache-log4j-2.6.2 bin

3)上面的文件夹在我的System classPath环境中变量C:\ eclipse \ apache-log4j-2.6.6.2 bin

4)该项目包含以下log4j.properties文件root

    # This sets the global logging level and specifies the appenders
log4j.rootLogger=INFO, theConsoleAppender
    # settings for the console appender
    log4j.appender.theConsoleAppender=org.apache.log4j.ConsoleAppender
    log4j.appender.theConsoleAppender.layout=org.apache.log4j.PatternLayout
    log4j.appender.theConsoleAppender.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

5)我已经清洁了该项目

6)导入失败是:导入org.apache.log4j.logger;

间歇性我也收到此错误消息

" type org.apache.log4j.logger无法解决.它是从必需的.class文件中间接引用的:

软件包com.example;

当我进行项目 - > Clean

时，此错误消失了

但是log4j导入的错误持续存在.

任何想法都将不胜感激.

其他推荐答案

检查您的Eclipse版本和Log4J依赖项版本.如果1.2.17不起作用，请使用1.2.16.

检查

Eclipse, Selenium, Windows

The import org.apache.log4j cannot be resolved

I have followed all the documented steps I can find, i.e.:

1) the following two jar files are in the project build-path: log4j-core-2.6.2.jar and log4j-api-2.6.2.jar

2) the above two jar files are located in the following folder: C:\eclipse\apache-log4j-2.6.2-bin

3) The above folder is in my system CLASSPATH environment variable C:\eclipse\apache-log4j-2.6.2-bin

4) The project contains the following log4j.properties file in the project root

    # This sets the global logging level and specifies the appenders
log4j.rootLogger=INFO, theConsoleAppender
    # settings for the console appender
    log4j.appender.theConsoleAppender=org.apache.log4j.ConsoleAppender
    log4j.appender.theConsoleAppender.layout=org.apache.log4j.PatternLayout
    log4j.appender.theConsoleAppender.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

5) I have cleaned the project

6) failing import is: import org.apache.log4j.Logger;

Intermittently I am also getting this error message

"The type org.apache.log4j.Logger cannot be resolved. It is indirectly referenced from required .class files" at the first line:

package com.example;

This error disappears when I do a project -> Clean

but the error on import of log4j persists.

Any thoughts would be greatly appreciated.
