I get NoClassDefFoundError at jsoup library trying to run my project jar on other computer.
I added jsoup as maven dependency, added in project settings-modules-dependencies, though I get same Exc.
I run project via:
java -classpath lostfilm-1.0.jar project.start.Entrance
Please tell me where am I wrong.

Add the JSoup jar file to your classpath
java -classpath lostfilm-1.0.jar;jsoup.jar project.start.Entrance
Add this to your POM:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.1</version>
<configuration>
<mainClass>project.start.Entrance</mainClass>
</configuration>
</plugin>
</plugins>
</build>
and then run
mvn exec:java
from the root directory of your project. Running your code this way will pull in all your maven dependencies without adding them to command line.

I am making a JavaFX project (for the GUI) on Maven and for the moment I want to convert a StringBuffer object to JSON.
I tried to add the dependency org.json from Maven but there is a problem in pom.xml file
Missing Artifact org.json:json:bundle:20220924
I tried adding an older version of org.json dependency, it had the same issue
I tried a different dependency, everything was ok in the pom.xml file but I could not import it into my project (any dependency).
All dependencies return this error: The type org.json.JSONArray is not accessible
Lastly, I tried to download the json-java.jar from github and add it into a libs folder on the base project directory and added it in the pom file as a dependency but it could not be resolved either.

In the end I downloaded Maven again and extracted it into a folder and changed my environment variables on path. Maven is successfully installed on version 3.8.7
Thank you in advance for any help!
UPDATE
I should mention that I tried it on a new java project (without maven) and it works fine, by importing the .jar file from git-hub repository
I am planning to use Cucumber Test with Junit 5 in Maven. So I followed cucumber to install different maven dependency. I added a runner class to execute my cucumber tests
package pirate;
import org.junit.platform.suite.api.ConfigurationParameter;
import org.junit.platform.suite.api.IncludeEngines;
import org.junit.platform.suite.api.SelectClasspathResource;
import org.junit.platform.suite.api.Suite;
import static io.cucumber.junit.platform.engine.Constants.GLUE_PROPERTY_NAME;
#Suite
#IncludeEngines("cucumber")
#SelectClasspathResource("pirate")
#ConfigurationParameter(key = GLUE_PROPERTY_NAME, value = "pirate")
public class Runner {}
I also created a new folder name pirate under resources folder and move all .feature files into that new folder.
But when I execute mvn clean install, the command fails at testCompile:
It seems like the compiler can't read the package name?
Below is my pom.xml

My project structure is:
but if I comment out cucumber-junit-platform-engine dependency in pom.xml, the error is gone but it won't run the cucumber tests. Did I miss something here?
Not sure if it's related, but one of the error messages is like:
[ERROR] error reading /Users/xx/.m2/repository/org/junit/platform/junit-platform-engine/1.9.1/junit-platform-engine-1.9.1.jar; zip file is empty

ZipException opening "junit-platform-engine-1.9.1.jar": zip END header not found
Maven : error in opening zip file when running maven
following the procedure fixes the "cannot access " problem.
did you tried with a different scope than test for the cucumber-junit-platform-engine dependency?
On building my spring boot app using mvn clean package, the final artifact that is getting built, myapp.jar, is not having the version number included in the jar name.

Note: I created a new spring boot project using spring starter (through sts), and for this new project the jar has artifact version included in the jar name by default. So wondering if this a default feature why is this not the case for my project (by the way, i am maintainer of this project not the creator but i have to add this feature of including version number to jar name.)
You are overwriting the default behaviour of generating project names. This is because you define the finalName tag.
From the docs:
finalName: This is the name of the bundled project when it is finally built (sans the file extension, for example: my-project-1.0.jar). It defaults to ${artifactId}-${version}.
In your case it is defined as <finalName>gitlab-finder</finalName> which does not contain the version of the project. You either add ${version} to it <finalName>gitlab-finder-${version}</finalName> or remove the finalName tag.
I am using Maven to compile and package a Java application from the command line:
mvn clean
mvn compile
mvn package
These commands run without a problem. But when I try to run the generated JAR file
java -jar target/JarFile.jar
I get the following error:
Error: Unable to initialize main class com.company.Main
Caused by: java.lang.NoClassDefFoundError: com/google/api/client/json/JsonFactory
Which is a class from an external dependency. These dependencies are also managed by Maven (i.e., I am not supplying them locally, but listing them in my POM file.) Since I am able to run the application inside the IDE, I assume I am missing a step to make the dependencies available to the JAR file. Here is my POM file:

Could you point me in the right direction so that the dependencies are accessible at runtime?
To run your jar from commandline, you must either explicitly specify the classpath on the command line or build an executable jar:
How can I create an executable JAR with dependencies using Maven?
BTW: mvn package already executes mvn compile, so you need not call mvn compile explicitly.
Use this in your pom.xml and rebuild your project.

I'm having issues with my Maven project. I am trying to use the command "mvn clean install" but I'm having no success. I have updated & cleaned the Maven project in the Eclipse IDE.

Any help would be greatly apreciated!
The problem is the Maven version (BTW which one are you using?)
When I run my Thorntail project using eclipse's embedded maven (version 3.5.3 ) it works.
When I run it using my local maven (version 3.6.0) I get the same error.
Solution: use a compatible version of maven. ( try 3.5.3 or 3.5.4) both work without issues with thorntail.
If you want to configure a different eclipse maven version go to:
Eclipse -> preferences -> Maven -> installations
there you can add a new one.
There's a problem due to third-party dependencies in Thorntail 2.x, that are incompatible with latest Maven release. The new Thorntail version should be the 2.3.0.Final once released.
On GitHub, you can track the status of the issue here
