为java编译设置slf4j的类路径

Question

我在设置classpathfor slf4jfor 时遇到问题compiling java files.我尝试了两种方式:1.提供classpath的command line

javac -cp /Users/page/.m2/repository/org/slf4j/slf4j-log4j12/1.7.5/slf4j-log4j12-1.7.5.jar src/main/java/com/scg/domain/*.java src/main/java/com/scg/util/*.java

这给出了以下错误:

src/main/java/com/scg/util/ListFactory.java:8: error: package org.slf4j does not exist
import org.slf4j.Logger;
                ^
src/main/java/com/scg/util/ListFactory.java:9: error: package org.slf4j does not exist
import org.slf4j.LoggerFactory;
...../long error message

1. 我试图export将CLASSPATH我的env变量.

export CLASSPATH=/Users/page/.m2/repository/org/slf4j/slf4j-log4j12/1.7.5/slf4j-log4j12-1.7.5.jar

当我尝试时,这也没有帮助并导致同样的错误

javac src/main/java/com/scg/domain/*.java src/main/java/com/scg/util/*.java

我正在尝试将compile所有java文件分成两部分packages.但我需要slf4j在我的课程中. but somehow I am not able to get it work. 感谢

Answer 1

这种依赖是api:

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.5</version>
</dependency>

您需要在类路径中使用slf4j-api.jar进行编译,而不是slf4j-log4j12.jar.

它在maven中工作,因为binding-lib(slf4j-log4j12)依赖于api,因此maven也加载了它,而没有你明确地将它定义为依赖.
