I know that people have asked this question before but none of them are using the Dropwizard framework.
Here is what I have tried:
Different versions of Dropwizard using the pom.xml,
Adding commons-lang and commons-text don't seem to fix it, though commons-text makes it throw a different error,
Restarting my computer.
It is a pretty involved pom.xml file which I am not comfortable sharing...
Any ideas why this is happening?
Is it possible, that you compile with a newer version (like Java 8) and run it with an older version (Java 7)? If yes, check the Path. (1)
Another thing could be, that the apache libraries are compiled with a more recent version.
(1) Try comparing the output of java --version and javac --version

I am new to Java and trying around. Now I would like to learn about network - server client communications. Long story short I found jars on github which should make the start easier. So I downloaded the file and added it to my Modulepath. Everything looked OK while writing a simple start to just connect but when I want to run for testing I get the NoClassDefFoundError ...

I do not have any idea what am I doing wrong, the jar should work otherwise it should not be there for download I guess. But the error comes from one of the jar classes called Server:
java.lang.NoClassDefFoundError: com/blogspot/debukkitsblog/net/Server
My platform has ubuntu 18.04.3 and openjdk version "1.8.0_242".
I'm running someone's executable jar file which references javax.vecmath.Vector3d, but the the openjdk vm generates NoClassDefFoundError for that class, as displayed below. The javax class is installed on my system in /usr/share/java/vecmath.jar, I've verified that it contains javax.vecmath.Vector3d, so I provide that jar in the '-cp' option:
% java -cp /usr/share/java/vecmath.jar -jar cameraCalc.jar
But I get this error:
java -cp /usr/share/java/vecmath-1.5.2.jar -jar cameraCalc.jar

Why can't the jvm find that class even though it's in the vecmath.jar provided as a '-cp' option?
Thanks
Tom
My problem was due to running an executable jar file that does not contain all needed classes. From the documentation:
When you use this option, the JAR file is the source of all user
classes, and other user class path settings are ignored.
So "-cp" options will be ignored when running an executable jar file.
got a problem, can't manage it to work for me right.
Completed my java project and i want it to compile and run for a test. I do compile it as "Jar file" (not runnable jar file). I compile it through Eclipse IDE.
I do not setup any more references in compiling settings, making everything stock. Once i compile it as "Server.jar" in my desktop i'm trying to run through console, because it's more like console program. I'm using macOS.
Using command : java -jar Server.jar

What should i do?
It shouws class is not found if i'm right?
This : org/json/simple/parser/ParseException is not recognised.
What i have tried : java -classpath ~/Documents/Java/Server/src/server/json-simple.jar -jar Server.jar
As all of you see, i'm using json-simple.jar library, moreover i do use mysql library, so i guess later it will be the same problem with mysql library.
Any solution? Tired of getting it working now..

NoClassDefFoundError means Java couldn't find the Class it was looking for. That normally means:
You defined wrongly the classpath.
Java is finding and using the wrong version of the jar (probably because of Maven dependency hell).
Solution for 1 is to check the classpath: make sure you are including the jar that defines org.apache.spark.sql.SchemaRDD.
Solution for 2 is to check if you have a Maven dependency that depends (transitively) on an older version of the resource that defines that class.
