英文:
Can not import log4j from CLASSPATH
问题
我正在使用Linux，并且在一个目录中有以下文件：
- logtest.java
- log4j2.xml
- log4j-api-2.13.1.jar
- log4j-core-2.13.1.jar
在logtest.java文件中，我使用以下行导入了log4j库：
import org.apache.logging.log4j.*;
我的CLASSPATH是/path/to/directory:/path/to/directory/log4j-api-2.13.1.jar:/path/to/directory/log4j-core-2.13.1.jar。
当我执行javac logtest.java时，我得到以下错误：
error: package org.apache.logging.log4j does not exist。
但是，当我执行javac -cp /path/to/directory:/path/to/directory/log4j-api-2.13.1.jar:/path/to/directory/log4j-core-2.13.1.jar logtest.java，它可以工作。
为什么在没有-cp参数和CLASSPATH的情况下无法找到该包？

I am using linux and I have the following files in a directory:
- logtest.java
- log4j2.xml
- log4j-api-2.13.1.jar
- log4j-core-2.13.1.jar
In the logtest.java file, I am importing the log4j library with this line:
import org.apache.logging.log4j.*;
My CLASSPATH is /path/to/directory:/path/to/directory/log4j-api-2.13.1.jar:/path/to/directory/log4j-core-2.13.1.jar .
When I execute javac logtest.java, I get the following error:
error: package org.apache.logging.log4j does not exist.
But when I execute javac -cp /path/to/directory:/path/to/directory/log4j-api-2.13.1.jar:/path/to/directory/log4j-core-2.13.1.jar logtest.java, it works.
Why is it unable to find the package without the -cp argument and from the CLASSPATH?
