I've ben having trouble setting up and testing Geb.
I have a simple Groovy script:
import geb.Browser;
println("Test 11")
Browser.drive {
go "http://www.google.com"
}
and I always get the following error:
Caught: java.lang.NoClassDefFoundError: geb/error/UnableToLoadException
java.lang.NoClassDefFoundError: geb/error/UnableToLoadException
at geb.Browser.<init>(Browser.groovy:61)
at geb.Browser.drive(Browser.groovy:1028)
at geb.Browser$drive.call(Unknown Source)
at Main.run(Main.groovy:8)
I wrote a Class.forName("geb.error.UnableToLoadException") which changed the error to
java.lang.NoClassDefFoundError: geb/error/GebException
at Main.run(Main.groovy:10)
Caused by: java.lang.ClassNotFoundException: geb.error.GebException
... 1 more
It seems to me that Geb is searching for a class GebException, which is not inside the geb-core-2.1.jar I've downloaded! Next to this jar, I also added the selenium-server-standalone-3.9.1.jar. Am I doing something wrong? Did I install some wrong geb-core library? I am using IntelliJ IDEA as the IDE. Thank you for your help
Best regards
If this is a maven project where yourfile is in, I suggest to check your dependency list in pom.xml first.
As I tested in my env, it is executing perfectly

Ah, please try to search the log, it is possible a ExceptionInInitializerError was happened before, so this time the JVM throws NoClassDefFoundError directly because it was failed last time.
Need to get the call stack of the original ExceptionInInitializerError (if it exists) in order to fix this issue.

https://github.com/openjdk/jdk11u/blob/jdk-11+28/src/java.base/share/classes/sun/security/jca/ProviderConfig.java#L308 - the class ProviderConfig$ProviderLoader was defined inside OpenJDK 11 so it is not likely to a Java classpath issue
https://stackoverflow.com/a/5756989/2412606 - See definition of NoClassDefFoundError here. thanks to #oldpeculier and #jared
For this problem not very clear why occur. in order to fix the problem. we can manual use Security.addSecurity method to load jca or analogous component again. like BouncyCastle. now it work fine for me.
I was using Java 11 and the project was build using Java 1.8. Once I switched to Java 1.8 it worked fine
I am trying to run Quarkus demo project from here. But when I run the command ./mvnw compile quarkus:dev, it fails to run with the following errors

Caused by: java.lang.ClassNotFoundException: io.quarkus.dev.DevModeMain
I mention, that I've tried the possible solution presented in this issue https://github.com/quarkusio/quarkus/issues/1707, but none of them worked.

I am doing some maintenance to a JAVA backend written using bundles. When running the code after doing some software upgrade, I get that error at first:
! java.lang.NoSuchMethodError: org.osgi.framework.BundleContext.registerService (Ljava/lang/Class;Lorg/osgi/framework/ServiceFactory;Ljava/util/Dictionary;) Lorg/osgi/framework/ServiceRegistration;
When running it a second time, it gives me the following error:
! java.lang.NoClassDefFoundError: Could not initialize class com.sap.hilo.orchestration.workspace.HiloWorkspaceFactory
Then, it keeps showing the second error for any extra code runs. Any clues how resolve this issue?
Regarding:
java.lang.NoSuchMethodError: org.osgi.framework.BundleContext.registerService
I found an answer to a similar question here: OSGi: servicereference.getBundle().getVersion() - No such method error
In the Import-Package section of the pom.xml file you'll need to change the org.osgi.framework version to at least 1.6 or give it a range [1.6,2.0)
When I try to do a simple "Hello World" java application I get this error:

I am running on Mac OS 10.8.1 and am running Java 1.6. I have checked my run configurations to make sure the main argument can be found. For the sake of simplicity I have also tried to use the default JRE of java 1.6 that is included with mac. The build configuration I have used is also correct and pointed to the right place.
When I followed this tutorial online, and executed the commands over the terminal I get the same error. What am I missing? I don't think it is an Eclipse problem anymore, but something bigger. Any advice would be greatly appreciated.
Here is the code I tried to run:
public class Test{
/* This is my first java program.
* This will print 'Hello World' as the output
*/
public static void main(String[]args){
System.out.println("Hello World");// prints Hello World
}
}
I put the code on my Desktop for simplicity. I went to /usr/tyler/desktop then made the script an executable with "javac Test.java", and when I tried to run it with "java Test.java" I then got the error.
Here are the other tutorials I have followed:
-Java Compilation error on Mac
-HelloWorld with Eclipse on Mac
-Along with many others from SO and elsewhere
EDIT:
Thank you for the help. The terminal issue has been resolved. However, if anyone has any advice on what could be going wrong with Eclipse, that would be appreciated.
You need to run ...
"java Test"
You cannot execute the java code, you need to execute the compiled class file. The java executable will look for a .class file with the name Test.
execute or run
java Test
instead of
java Test.java
I want to deploy a java appa on HEROKU. I am new to maven. I made all set up as per in the deploy a sample app to heroku (java+maven+ tomcat7)documentation.
and i made a bulid,It was successfull. But as soon i typed sh /target/bin/weapps i am getting the following error. Can anybody help me to sort out this issue.
Exception in thread "main" java.lang.NoClassDefFoundError: launch/Main

I had a similar problem, I (well, almost) solved it this way, just remove:
<packaging>war</packaging>
from pom.xml. I know this is not an ideal solution, but somehow the embedded tomcat plugin doesn't work with war packaging!
I don't have enough points to comment, but what article are you following? Can you link it?
Based on the error, I suspect your Main.java is not in src/main/java/launch. If you follow these instructions, I think you should be able to clear up the error:
http://devcenter.heroku.com/articles/create-a-java-web-application-using-embedded-tomcat
If that's the article you're following and you're still having trouble, it may ease the problems you're having if you simply clone the sample repo:
git clone git://github.com/heroku/devcenter-embedded-tomcat.git
Since you said you are new to maven, I think the reason of this error is that you simply put your *.java code under the root folder of the project, while you are rather expected to put it under ./src/main/java/
This should work for you. I experienced the same problem and figured this out.
This is probably dead, but in case it helps people of the future.
I was getting up and running with a java app on Heroku, using an Ubuntu machine for development - and got this same Exception in thread "main" java.lang.NoClassDefFoundError.
Double check that you're using the same java compiler version as your java sdk version.
type java -version & javac -version. Make sure they are the same version.
If not, you can fix this by reconfiguring your environment to use the same for both.
Assuming you have downloaded and installed the java version you want to use, type :
`sudo update-alternatives --config java`
You'll get a nice menu with options
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java 1061 auto mode
1 /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java 1061 manual mode
2 /usr/lib/jvm/jdk1.7.0/bin/java 1
Select the version you wish to use. Done.
Now try to build.
