setting classpath for slf4j for java compiling
提问by eagertoLearn
I am having a problem setting up the classpathfor slf4jfor compiling java files.
I tried two ways:
1. provide the classpathin command line
我有一个问题，设立classpath了slf4j为compiling java files。我尝试了两种方法： 1. 提供classpathincommand 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
This gave the following error:
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
- I tried to
exporttheCLASSPATHto myenvvariable.
- 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
export CLASSPATH=/Users/page/.m2/repository/org/slf4j/slf4j-log4j12/1.7.5/slf4j-log4j12-1.7.5.jar
This did not help either and resulted in same error, when I tried
当我尝试时，这也没有帮助并导致相同的错误
javac src/main/java/com/scg/domain/*.java src/main/java/com/scg/util/*.java
I am trying to compileall the java files in two packages. but I need to have slf4jin my classpath. but somehow I am not able to get it work.
Thanks
我正在尝试将compile所有 java 文件分成两个packages. 但我需要slf4j在我的类路径中有. but somehow I am not able to get it work.
谢谢

This dependency is the api:
这个依赖是api：
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.5</version>
</dependency>
You need the slf4j-api.jar in your classpath for compiling, not the slf4j-log4j12.jar.
您需要在类路径中使用 slf4j-api.jar 进行编译，而不是 slf4j-log4j12.jar。
It worked in maven because the binding-lib (slf4j-log4j12) has a dependency on the api and thus maven loads that as well, without you explicitly defining it as a dependency.
它在 maven 中工作，因为 binding-lib (slf4j-log4j12) 依赖于 api，因此 maven 也会加载它，而无需您明确将其定义为依赖项。
