How to build standalone executable cucumber jar file?

I want to create a executable jar file so anyone can run it from their computer with least install require components.
I found several tutorial but none of them a work.
When I execute jar file I've built they are return error like:
Error: Could not find or load main class fully.qualified.MainClass
Caused by: java.lang.ClassNotFoundException: fully.qualified.MainClass
OR like this:
Error: Could not find or load main class io.cucumber.core.cli.Main
Caused by: java.lang.ClassNotFoundException: io.cucumber.core.cli.Main
My project run from Intellij with no problem.

I've run mvn clean compile assembly:single, it's output a CucumberSelenium-1.0-SNAPSHOT-jar-with-dependencies.jar file, but it wont runs.

I just came across a similar issue and, despite trying the ubiquitous
java -cp . org.example.Main
(while on current directory being where the Main.class is), I kept getting this dreaded
"Error: Could not find or load main class"
I eventually resorted to comparing the actual command with parameters invoked by IntelliJ (on IntelliJ IDEA's debug log) with mine, and discovered that the following solves the issue:
java -cp C:\Users\WebViwer\IdeaProjects\MyProj\target\classes org.example.Main
I am guessing that once the fully qualified class name is specified, the current directory (where the class resides) is no longer valid as a classpath: Only the top level classes directory should be specified (in this org.example, 2 levels up).

You have a a few problems going on.
The maven-assembly-plugin should not be a in the dependencies section. It is not a dependency used by the runtime code of your project.
Your step definitions, feature files and glue code located in src/test are not included in the jar file build by the assembly plugin.
Your test scoped dependencies will also not be included by the assembly plugin either.
You must configure the containerDescriptorHandler of the assembly plugin with metaInf-services or the plugin will not merge files in META-INF/services correctly.
You can verify most of these by opening the generated jar file (it's a .zip file in disguise).
My project run from Intellij with no problem.
When running tests in Intelij you are using the test scope, the jar file only includes runtime scoped code.
For a more comparable test you must create a new run configuration that invokes the main method.
I found several tutorial but none of them a work.
It appears that you are relatively new to Java and Maven. It would be prudent to follow a proper course first rather than tutorials. You are missing fundamental knowledge that is generally not taught in tutorials.
I want to create a executable jar file so anyone can run it from their computer with least install require components.
It's also prudent to consider why you are doing this.
Tests will typically change as quickly as the source code they are testing does. Manually distribution of jar files won't keep up with this.
This means it's generally better to integrate the tests and the test source code into the automated build pipeline of the project they test.
This also means that you don't need to distribute your tests as a jar. Rather you should expect (and possibly train) people to use Maven, GIT and Java.

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile)

I know this is a duplicate question but the answers on other topics didn't help me.
I'm using Eclipse Photon, Java Version :10, I've set jdk/jre versions on 10 in eclipse and pom.xml file. I've changed eclipse.ini file :

The dependencies aren't being read in class files and also I've tried deleting .m2 repository and starting Eclipse and doing the : Maven->Clean, Maven->install, and than Maven->update project. Nothing helped. I'm really stuck here for about 2-3 hours now.
Note: in Windows->Preferences->installed JRE's the jre10 was marked with the tick. I changed it to mark the jdk10. but still error :
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project spring-security-demo-06-user-roles: Compilation failure
Everything was working fine until I added the dependency of : spring-security-taglibs.
Deleting the dependency doesn't do anything aswell.

Check properly settings with version of your project in eclipse and version of your runner for maven.
I have reproduced the same issue with maven-compiler plugin, but using version 3.8.1:
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project testName: Fatal error compiling
My POM was:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>11</source>
<target>11</target>
</configuration>
</plugin>
To clarify:
in project I'm using Java 11 and IntelijIDEA (but logic I think the same for eclipse). So I'm using maven lifecycle phases fine only if my version of project (check properly Project Structure -> Project Settings) corresponds to version of maven runner.
E.g. if version of runner is for java 8, but project settings are for Java 11 then I'm getting this error. If I have the same for both then I don't have any problems.
And I highly recommend to check all settings for maven and the whole project. It helps to avoid the issues in the future. Deleting folder for maven is as alternative solution, but it must be last thing that you need to do.

It started working Automagically . FIX : delete .m2 repository.
I did that yesterday but it didn't help, today somehow, deleting the .m2 repository and updating the project helped !

Confirm, delete your entire local repository pointed to by .m2/settings.xml, usually this is .m2/repository

I updated my Java SDK to 11.9 and reloaded the project. With this I solved my problem.

I had the same issue, it was because the Spring Boot project was using Java 11 but my %JAVA_HOME% variable was pointing to Java 8 home directory. I resolved the issue by changing the path to %JAVA_HOME% variable.

You just need to go to preference(eclipse in this case) and change the right version of JDK like below in pic:

When trying to convert selenium project to maven project .. is showing me byte buddy.jar error

Archive for required library: 'C:/Users/TOPS/.m2/repository/net/bytebuddy/byte-buddy/1.7.5/byte-buddy-1.7.5.jar' in project 'Maven1' cannot be read or is not a valid ZIP file
this is the error which is shown in Problem window in eclipse
Steps I have done to convert seleniumn project
Create a simple selenium webdriver project
convert it to maven project
remove all the selenium jar from the library options
In pom.xml add all the dependencies
Add the JRE and Maven from Add library options
Then it is showing me this error.
My pom.xml file is this
if there is anything missing then plz tell me

About Byte Buddy
Byte Buddy is a Java library for creating Java classes at run time. This artifact is a build of Byte Buddy with a remaining dependency onto ASM. You should never depend on this module without repackaging Byte Buddy and ASM into your own namespace.
As you are seeing an error as Archive for required library: 'C:/Users/TOPS/.m2/repository/net/bytebuddy/byte-buddy/1.7.5/byte-buddy-1.7.5.jar' in project 'Maven1' cannot be read or is not a valid ZIP file I will suggest the following steps :
Remove all the dependencies and do maven clean and maven install
Add the required Selenium dependency only
Either add selenium-server or selenium-java as a dependency as per your exact requirement.
Use only the latest Selenium dependencies from Maven Artifact current one being <version>3.7.1</version>
Use only compatible junit dependencies
I can see you have used the surefire-booter dependency as follows (cross check if you need it):
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-booter</artifactId>
<version>2.20.1</version>
</dependency>
Finally, the maven-surefire-plugin is clearly missing. You need to add the following plugin :
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.17</version>
<configuration>
<suiteXmlFiles>
<suiteXmlFile>${suiteXmlFile}</suiteXmlFile>

</configuration>

When I do a maven dependency resolution, its taking forever to get it through and this is what I get:
And it sticks here forever.
Here are my maven settings:
I followed steps given in this SO answer.
Please let me know where am I doing wrong and how do I get rid of it.
EDIT
If this should help, I am trying to run this code: https://github.com/hmkcode/Android/tree/master/java-post-gcm
I am not sure whether its an issue with the pom.xml itself. Perhaps if someone is able to have it working on his IDE, it may be concluded that its an issue with my specific IDE config.

If this is an issue very specific to intellij, I would suggest do the following steps
You can try running mvn clean install.(Depending on your network speed it will pull every dependency)
Change intellij settings in
Preferences->build,execution,deployment->maven->Maven home directory->{now change this to point to your mvn home rather than bundled mvn}
mvn -v in command line should give you the maven home path.
Now it won't try to download dependencies again.

File | Settings | Build, Execution, Deployment | Build Tools | Maven |
Threads (-T option) | 8 (or however many threads you want to try)
mvn compile -T 8
I had the same issue. Maven was taking an hour in IntelliJ and also running from the command line. Using the -T parameter you can tell Maven to use more threads to download artifacts simultaneously. Takes only about 15 minutes now.
Don't use bundled mvn. Point "Maven home directory" to the path on your file system.
After you're done building. Check "Work offline". This stops mvn from searching remote websites each time you build. Uncheck when you update your POM file so it can search for the changes.
You can also skip tests. This is evertyhing from the command line.
mvn clean install -T 8 -o -DskipTests

Select File, Settings, then set VM options for Maven importing to -Xms1024m -Xmx2048m.
Visit https://www.programmersought.com/article/56414660398/

For me, issue was related to https://repo.maven.apache.org/maven2 and it was not responding.
I added another mirror(maven-central.storage.googleapis.com) in settings.xml

mvn generate-sources fails, why isn't xml beans on classpath?

I'm trying to generate java classes for OGC KML 2.2 as part of the maven generate-sources process using the org.codehaus.mojo xmlbeans-maven-plugin. The java code appears to be generated correctly, but I get tons of errors during compilation complaining that 'package org.apache.xmlbeans'. XMLBeans is clearly a dependency, it exists in my ~/.m2 repository, and I've been peek in the jar to make sure the classes are there. It looks like XMLBeans is successfully generating java files in target/generated-sources, but somehow its absent from the classpath during compilation.
I've tried changing the scope of the org.apache.xmlbeans dependency, but to no avail.
Here's the pom.xml

The project consists of a single src/main/xsd folder containing the two xsds from http://schemas.opengis.net/kml/2.2.0/. The entire folder structure is at https://github.com/iancw/maven-xmlbeans-question.
I can compile the classes by hand if I put the xmlbeans jar from my ~/.m2 repo on the classpath, e.g.
xmlbeans$ javac -classpath ~/.m2/repository/org/apache/xmlbeans/xmlbeans/2.4.0/xmlbeans-2.4.0.jar org/w3/x2005/atom/*.java org/w3/x2005/atom/impl/*.java net/opengis/kml/x22/*.java x0/oasisNamesTcCiqXsdschemaXAL2/*.java x0/oasisNamesTcCiqXsdschemaXAL2/impl/*.java net/opengis/kml/x22/*.java net/opengis/kml/x22/impl/*.java
Note: Some input files use unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
xmlbeans$
I've looked through a number of examples and it seems like I'm doing this right. I haven't seen anyone else complain of this issue. Any maven mavens have suggestions?
(A curious side note is that although i've tried both 2.4.0 and 2.6.0 of the xmlbeans dependency, maven hasn't ever seemed to download the 2.6.0 version into my repository)

From the POM file that you've included in your question you have only defined the xmlbeans dependency in the dependencyManagement section. You also need to define it in your dependencies section of your POM before it will be included in the classpath at build time.
So for example your POM would be:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>xmlbeans-maven-plugin</artifactId>
...
</plugin>
</plugins>
</build>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.apache.xmlbeans</groupId>
<artifactId>xmlbeans</artifactId>
<version>2.6.0</version>
</dependency>
</dependencies>
</dependencyManagement>
<dependencies>
<groupId>org.apache.xmlbeans</groupId>
<artifactId>xmlbeans</artifactId>
</dependencies>

One Additional issue that may look similar,
Check your java install jdk and ext folders for older beans jar.
The plugin puts the project dependencies at the end of the classpath.
