I have one app which I want to dockerize. But first, I need to run it via console(cmd or bash). When I run it from Eclipse everything is okay, but when I run it from bash(java -jar project-18.5.0-SNAPSHOT.jar) I get this error

I have that jar in m2 and he has this LogFactory class. Mvn clean install is success. But for some reason I can't run it via console. I don't know is there some way to get that classpath from Eclipse or there is another way to solve this.
Similar questions about this logging exception didn't help me.

I am not particularly well experienced with Java at all and try to get a jar file running on my Ubuntu machine (https://sites.google.com/site/communitydetectionslpa/home).
However once I run the jar file with the command suggested by developers I receive the following error:
java -jar GANXiSw.jar -i test.ipairs

Apparently java is not able to import the org.apache.commons class properly. After some researching I checked if I have libcommons-collections3-java installed, which however is the case.
I read something about adding the library explicitly to my CLASSPATH, which however I also read to be not good practice.
What is the best approach to fix my issue?

I have written a number of selenium tests using Maven and TestNG that are intended to be ran overnight via Jenkins. However, it has been requested that I write some more specific tests that the QA team can run independently from Jenkins, with specific parameters (sku, etc). Currently my automation tests are ran with maven, but how can I run them from the command line using the testing command, so it will run only run a specific file with command line options? I tried this:
java -cp "/Users/kroe761/.m2/repository/org/testng/testng/6.8/testng-6.8.jar" org.testng.TestNG testng2.xml
But I got this error (which I don't understand at all)

If there is a way to do this with mvn test then that would be even better, but I don't want to have modify the Jenkins job too much.
You can provide suiteXmlFiles params case you're running your tests using surefire plugin, like described in here
When running from command line it should look like this:
mvn test -Dsurefire.suiteXmlFiles=suite_location/suite.xml
I am trying to run a simple junit test using OS X and terminal. I have placed the Junit jar file inside my java folder. I was able to compile all of the files using:
javac -cp .:"/Library/java/junit.jar" *.java
It compiles just fine, with no errors. However when I try to run the command:
java TestRunner
It gives the error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/junit/runner/JUnitCore

I cannot seem to find what I am doing incorrectly. Any help solving this would be greatly appreciated.
Like #ToddSewell said, the external libraries should be in your classpath for the execution too. Try this:
java -cp .:"/Library/java/junit.jar" TestRunner
In my program I have several modules placed in different folders and all of them are dependent on a "core" module.
I have already setup a configuration for Intellij to run the program, but every time I try to run I receive a ClassNotFound Excpetion. I'm not sure if this is due to my core module having a similar packages i.e. com.adpetlabs.flappybird
Could the problem be related to the packages or something else? I really need help in resolving this
