log4j runtime NoClassDefFoundError

I am using log4j in android jar module. I can build the jar file successfully and run it in AndroidStudio successfully.

My gradle config is:

implementation 'log4j:log4j:1.2.17'

But when I try the jar file from command line:

java -jar test.jar

I got below error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/Logger
    at com.yeetor.Main.<clinit>(Main.java:39)
Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Logger
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:335)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 1 more

Why it can run in AndroidStudio but not work from command line?

Refer to this SO, to generate one jar file include dependency. the dependency should be included using "compile" but not "implementation", then you will get a bigger Jar file include all dependency. Usually gradle will not include dependency in Jar file but generate all each dependency as a single jar file.
