在Unix中编译slf4j

Question

I have a Java program that uses slf4j-api-1.7.10.jar and slf4j-simple-1.7.10.jar . I have tried to compile it in my Unix shell like so:

javac -cp "$CLASSPATH:.:slf4j-api-1.7.10.jar:slf4j-simple-1.7.10.jar" Test.java

Running java Test results in this error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
        at SystemCommandExecutor.<clinit>(SystemCommandExecutor.java:13)
        at Test.main(Test.java:12)
Caused by: java.lang.ClassNotFoundException: org.slf4j.LoggerFactory
        at java.net.URLClassLoader$1.run(URLClassLoader.java:217)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:268)
        ... 2 more

I am able to run the program in Windows with the two jar dependencies, so I don't believe I need any extra jars. Perhaps I am issuing the wrong command to compile in Unix as I am fairly unfamiliar with the syntax.

Answer 1

Why you don't create a pom.xml for compile it with a maven dependency?

In that case you should include the package for the main class:

javac -classpath external.jar com/yourpackage/yourMainClass.java

Also check your syntax for the slf4j inclusion.
