I'm trying to build this project from github:
https://github.com/tomakehurst/wiremock
The thing is, when I download it and run gradle build, I don't think all the required jar files are being loaded onto the class path. I get this error when I actually try to run the thing:
Exception in thread "main" java.lang.NoClassDefFoundError: joptsimple/OptionParser

What gives? Isn't grade supposed to have downloaded this dependency by itself?
Try to execute gradle clean build jarAll
See this github issue for reference
From what I see in the build code, the task jarAll handles the joptsimple classes (and various others)

The strange thing is that I don't use the missing class DispatchApplication and because I have no error when launching it using idea, so i do not know how to debug it.
I tried to clean idea cache, clean local maven repository, restart my PC
but my colleague can run with a jar, and each of them don't know why this happen and how solve this

This looks to be an issue with dependencies.
You might want to check your IDE settings if you have explicitly enabled any additional jars in the class path.
Also, check out your pom.xml/.gradle file for any difference in dependency versions.
If this class is part of some custom jar, make sure you include it while packaging your jar.
At the moment I'm trying to run my first flink application. I already tested the java file (KMeans.java) in the IDE and it works perfectly but I can't handle to get this java file run as an jar in command line.
The build was successfully created with mvn clean package.
But if I run my jar file in command line flink run -c KMeans name.jar
this error message appears:
The program finished with the following exception:
org.apache.flink.client.program.ProgramInvocationException: The
program's entry point class 'KMeans' was not found in the jar file.

So I looked up my generated target folder and there is a KMeans.class file in the classes folder. So I'm doing this wrong?
You need to specify the full class name, e.g., org.apache.flink.examples.java.clustering.KMeans.
Note that you only need to use the -c flag if the JAR file doesn't specify the class to run in its manifest.
Using Maven I am creating a jar-with-dependencies for a project that uses ClasspathSuite to create a JUnit test suite. When running the jar from the command line I am running into an issue where the project classpath isn't being supplied like it would be in Eclipse.

I need the project classpath so that ClasspathSuite can scan my files to build a junit class suite. I have been searching a number of ways to allow maven to include the classpath in my pom such as <additionalClasspathElements> or <Class-Path> but I cannot get the value to appear in the system property java.class.path. At this point I am unsure if I am just walking down a rabbit hole that isn't going to work.
Is it possible to have a classpath in my jar's manifest that will point to one of the jar's directory? In this case ./com/....
How can I have this classpath referenced so that maven will include it when the jar is executed?
I am getting java.lang.ClassNotFoundException: org.codehaus.jettison.mapped.MappedXMLOutputFactory error while running mule application. I checked jettison-1.1.jar jar is already there in my application folder lib directory but still I am getting this error.
I am getting this error while initialising Spring batch job repository.

You need to add jettison.jar file to your project.

I am trying to create the concordion-extensions-demo (located at http://concordion.org/Download.html) project with Maven.
When I run the command mvn test I receive errors ...

at java.lang.ClassLoader.loadClass(ClassLoader.java:356)
In the POM there are variables for ..
concordion.version, concordion-extensions.version and slf4j.version.
Do I need to update these tags with actual version numbers?
As is probably obvious I am not an experienced software devoloper or have much experience with Maven. Does anyone have an idea as to what the problem could be and how I could resolve this?
Thanks.
Tam.
