I am using the IntelliJ IDEA to create a jar artifact from a LeanFT project.
The jar artifact was generated, but with the following error message:
JNI error has occurred, please check your installation and try again
when trying to execute the jar file directly.
It is working when I use the IDE for execution. No arguments or parameter values are required. I am getting the same error when I generate a jar file from a simple "Hello World".

I looked into the exception you got : Invalid signature file digest for Manifest main attributes.
Are you using signed jar files as dependencies of your project? If so, when you generate a jar containing the dependencies, then try to execute it - the JVM detects your generated jar as a manipulation of the signed jars you are using.
Here is a list of questions where this exception was encountered:
Valid JAR signature for JavaFX projects
“Invalid signature file” when attempting to run a .jar
Invalid signature file digest for Manifest main attributes
Re: [iText-questions] Invalid signature file digest for Manifest main attributes
Follow the links above and find the exact solution which will help you. The solution depends on what exactly you are doing, deployment-wise (specifics of how you are creating your jar artifact).
It's likely something to do with the version of java installed on your PC. check that it is the same as the java version being used to compile your code.

UPDATE:
I have taken a look at the kafka.jar mentioned - which seems to be added to the classpath by the CMD files that run the distributed worker - kafka-run-class.bat in particular and it is less than 1kb so doesn't seem to be a valid JAR - so maybe that first error is a red herring. But that aside if it runs on, the distributed worker just spits out a load of errors about ClassNotFoundException, then goes on to say every config value provided in my distributed properties config file is not recognised, and doesn't try and load any plugins
ORIGINAL question
I am simply trying a very simple test of starting a Kafka Connect distributed worker, no plugins yet - just trying to get the basic worker going.
My distributed config is pretty stock
bootstrap.servers=GBV04303950:9092,GBV04303950:9082
group.id=connect-cluster
key.converter=org.apache.kafka.connect.json.JsonConverter
value.converter=org.apache.kafka.connect.json.JsonConverter
key.converter.schemas.enable=true
value.converter.schemas.enable=true
internal.key.converter=org.apache.kafka.connect.json.JsonConverter
internal.value.converter=org.apache.kafka.connect.json.JsonConverter
internal.key.converter.schemas.enable=false
internal.value.converter.schemas.enable=false

offset.storage.replication.factor=2
config.storage.topic=connect-configs
config.storage.replication.factor=2
status.storage.topic=connect-status
status.storage.replication.factor=2
However I get the following error

The only reason I can think of for this is my local drive is locked down and doesn't let you create folders unless you have Elevated rights. I am running this from a CMD prompt that was started with elevated rights but as I've noticed, this doesn't always translate down to passing those rights on to processes spawned from within the CMD prompt. But I'm not sure how I can provide elevated rights to the java process that's trying to unpack the JAR.
Also, that error is followed by a long stream of ClassNotFoundException, I assume because the above error means JARs cannot be unpacked to load all the required classes

Can anyone suggest if they think my theory about elevated rights is why this isn't working or how I could get around this?
Inside the share/java/kafka folder there is a kafka.jar about 26 bytes.
If you look at it with a text editor, you can see, that it is a link.
Copy the linked jar to kafka.jar.
On windows, you should also set the plugin.path to an absolute path.
You will get a few errors, while starting, that is due to missing aws and other jars.
I got a very strange problem that my program runs in Eclipse but doesn't run well wen exported as a runnable jar. I am getting ClassNotFoundException.

C:\Users\43156557\workspace\CAF3_IDE\MFTRelease>
ClassNotFoundException usually depicts that JVM is not able to load the required class file from the defined classpath (either the path is not correct or the class / jar is not present at the path).
The Error in current scenario might be cause have missed to include the Dependency libraries when creating the jar file. Since on eclipse you have the class-path correctly including those its working perfectly.
Make sure that you check "Package Required Jar into generated JAR" , this will include the jar files automatically from your eclipse build path.
for detailed info this might come handy Include Dependent Jars in Executable Jar

Note: com4j-20110320.jar, it is necessary to change the name to com4j.jar
Additional Info
The tlbimp of the latest version (tlbimp-2.1.jar), requires args4j-2.0.8.jar and com4j-2.1.jar.
In this version, file name change is not required.
From the stack trace, it looks like you are missing dependent jars from the java class path. The program seems to be looking for Koshuke's args4j library - http://args4j.kohsuke.org/.
Unjar tlbimp.jar and check out its manifest. It has a classpath where args4j and com4j must be in the same directory as tlbimp.jar and require specific names. The specifics of the name depend on the build and may or may not include version number. Name your com4j and arg4j as indicated and you're good to go.
I have a class names test.java and another file "log4j.properties" in the same folder but following call

But getClass().getClassLoader().getResource("log4j.properties") works. What can be the reason?
The InvalidJarIndexException is normally caused by a corrupt INDEX.LIST file in the JAR. So check the JAR for any problems. See http://littletechsecrets.wordpress.com/2008/12/01/why-does-invalidjarindexexception-occur/
The different results you describe are probably related to Class.getResource() resolving a path relative to the classes package, and ClassLoader.getResource() resolving a path relative to the root. So getClass().getResource("/log4j.properties") might fix your problem.
I have a very simple line of code in my source:
XMLReader xmlReaderFactory = XMLReaderFactory.createXMLReader();
This works flawlessly from an application, however, from an applet, it attempts to load a ".class" file from the server (no classname, just the extension just as you see) and then fails to give me a parser.

What could be the problem?
It looks as if you are attempting to configure the use of a SAX implementation other than that in the JRE. The configuration is pointing to a Windows text files starting with at least two empty lines. SAX implementations may be configured through the system property org.xml.sax.driver or contained in a file within a jar of the name META-INF/services/org.xml.sax.driver.
You might be getting back a 404 error from the server for that class file. See this bug report for details.
