cucumber.runtime.CucumberException: No backends were found

I am trying to run a BDD test with cucumber in a Maven project.
When I try to run BDDdemo.feature , I get the following error
Exception in thread "main" cucumber.runtime.CucumberException: No backends were found. Please make sure you have a backend module on your CLASSPATH.

I have tried the all solutions in stack overflow regarding this issue. But nothing worked for me.
Can anyone help me with this ?

I'm assuming that, according to your pom.xml snippet, you are using TestNG and Junit. Thus, you need to add both cucumber-testng (it's already there) and cucumber-junit (it's missing) as cucumber backends. Please consider adding this other dependency entry to dependencies section on your pom.xml:
<dependency>
<groupId>info.cukes</groupId>
<artifactId>cucumber-junit</artifactId>
<version>1.2.6</version>
</dependency>
PS: all the dependencies you listed seems to be test-scoped, so, consider add <scope>tests</scope> to each one of them to avoid unnecessarily adding those libraries to your final package (in case you are packaging a JAR).

Do you know how I can solve this issue?

Add below code or maven equivalent:
testRuntimeOnly "org.junit.platform:junit-platform-commons:1.7.0"
Explnation:
ClassNamePatternFilterUtils belongs to platfrom-commons which is transitive dependency. This class introduced in the 1.7.0 version. Hence, needs to explicity add the dependency.

For some reason in your project build path org/junit/platform/commons/util/ClassNamePatternFilterUtils.class is missing, but this can be found in junit-platform-commons (1.7.0)
for maven projects add this dependency to pom.xml file :
<dependency>
<groupId>org.junit.platform</groupId>
<artifactId>junit-platform-commons</artifactId>
<version>1.7.0</version>
</dependency>
for gradle projects add this dependency to build.gradle file:
compile group: 'org.junit.platform', name: 'junit-platform-commons', version: '1.7.0'

I fixed the issue using only:
<dependency>
<groupId>org.junit</groupId>
<artifactId>junit-bom</artifactId>
<version>5.7.0-M1</version>
<type>pom</type>
</dependency>

Problems creating JAXBContext in OSGI Bundle

Task: Batch process to transform data and store the result as XML-File on disk.
Problem: Marshalling objects, loading JAXBContextFactory in OSGI bundle.
Deadlock caused by java.lang.NoClassDefFoundError: org/eclipse/persistence/internal/libraries/asm/ClassWriter in FutureTask:311. No stacktrace or cause.
Question: What kind of setting or import do I miss to get the JAXBContext instantiation working?
Explanation:
For data processing I need to store my POJO Class as XML-File on Disk.
The POJO Class is generated from an xsd file with jaxb2-maven-plugin (xjc) filled in the batch process and then saved to disk where it will be further processed.
From an different Stack Overflow question I learned that OSGI uses different classloader and I have to use the right newInstance method to instantiate the JAXBContext. (Answer: https://stackoverflow.com/a/1043807/7461710).
This is my current newInstance call, The PrintDocument class is in the auto generated package com.some.package.generated and the ObjectFactory is in the same package and also generated by the jaxb2-maven-plugin.
The Programm fails during the newInstance call.
JAXBContext jaxbContext = JAXBContext.newInstance(PrintDocument.class.getPackage().getName(),
ObjectFactory.class.getClassLoader());
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
Logfile:
DEBUG XMLUtil:24 -Step 4/4: Save result into file. path: /somewhere/result.xml
DEBUG bind:282 - Searching jaxb.properties
DEBUG bind:300 - Searching the system property
DEBUG bind:565 - Trying to load org.eclipse.persistence.jaxb.JAXBContextFactory
[no further output]
We use bnd to Import packages, I have set the bnd.bnd file in the bundle to
Import-Package: \
org.eclipse.persistence.jaxb,\
*
As JAXB implementation I use moxy.
If I add this jaxb.properties file to the generated pojo package:
javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory
A regular class not found exception is thrown. Even in my unit test. (The unit-test performs the marshalling outside of the OSGI bundle)
javax.xml.bind.JAXBException: Provider org.eclipse.persistence.jaxb.JAXBContextFactory not found
- with linked exception:
[java.lang.ClassNotFoundException: org.eclipse.persistence.jaxb.JAXBContextFactory ]
at javax.xml.bind.ContextFinder.newInstance(ContextFinder.java:134)
at javax.xml.bind.ContextFinder.find(ContextFinder.java:293)
at javax.xml.bind.JAXBContext.newInstance(JAXBContext.java:431)
at javax.xml.bind.JAXBContext.newInstance(JAXBContext.java:394)
[...]
But if I change the newInstance call to JAXBContextFactory.createContext based on this Answer https://stackoverflow.com/a/6820113/7461710, my unit-test works again and the programm gets stuck in the Deadlock caused by java.lang.NoClassDefFoundError: org/eclipse/persistence/internal/libraries/asm/ClassWriter as mentioned above.

The default is com.sun.xml.internal.ws.developer.JAXBContextFactory but you should not set it in your bundle as it is a sun private package.
Instead try to use this in your OSGi framework properties:
org.osgi.framework.bootdelegation=com.sun.*
This will allow the JAXBContext to find an instantiate the default JAXBContextImpl.

Could not initialize com.ibm.mq.MQEnvironment

I've upgraded my maven dependencies for IBM MQ from these(version: 6.0.2.5):
<dependency>
<groupId>com.ibm</groupId>
<artifactId>mq</artifactId>
<version>${ibm-mq-version}</version>
</dependency>
<dependency>
<groupId>com.ibm</groupId>
<artifactId>mqjms</artifactId>
<version>${ibm-mq-version}</version>
</dependency>
<dependency>
<groupId>com.ibm.disthub2</groupId>
<artifactId>dhbcore</artifactId>
<version>DH610-Gold</version>
</dependency>
<dependency>
<groupId>com.ibm</groupId>
<artifactId>mqetclient</artifactId>
<version>${ibm-mq-version}</version>
</dependency>
To that(version: 7.5.0.5):
<dependency>
<groupId>com.ibm</groupId>
<artifactId>mq-jms-all</artifactId>
<version>${ibm-mq-version}</version>
</dependency>
Now, everytime I try to run my project, I get the following error:
nested exception is java.lang.NoClassDefFoundError: Could not initialize class com.ibm.mq.MQEnvironment
The maven-dependency is imported correctly and is also visible in Eclipse in the maven-dependencies-tab. Also i see the com.ibm.mq.jar in the classpath.
I've googled a lot and the only real solution, which worked for some people was, to add the connector.jar. But I'm already using the jar:
<dependency>
<groupId>javax.resource</groupId>
<artifactId>connector</artifactId>
<version>${connector-version}</version>
</dependency>
Am I missing something?

IBM MQ from these(version: 6.0.2.5):
To that(version: 7.5.0.5):
IBM moved the MQException to the 'com.ibm.mq.jmqi.jar' file.
As per the the MQ Knowledge Center, you need the following jar files for MQ JMS programming:
com.ibm.mq.commonservices.jar
com.ibm.mq.headers.jar
com.ibm.mq.pcf.jar
com.ibm.mq.jmqi.jar
connector.jar
jms.jar
dhbcore.jar
rmm.jar
jndi.jar
ldap.jar
fscontext.jar
providerutil.jar
CL3Export.jar
CL3Nonexport.jar

Exactly the same problem and this fixed it
<dependency>
<groupId>javax.resource</groupId>
<artifactId>connector</artifactId>
<version>${connector-version}</version>
</dependency>
These are my dependencies.

For Eclipse (Dynamic Web Project (Servlet)) you need copy files:
com.ibm.mq.commomservices.jar
com.ibm.mq.defaultconfig.jar
com.ibm.mq.headers.jar
com.ibm.mq.jar
com.ibm.mq.jmqi.jar
com.ibm.mq.jms.Nojndi.jar
com.ibm.mq.pcf.jar
com.ibm.mqetclient.jar
com.ibm.mqjms.jar
connector.jar
dhbcode.jar
fscontext.jar
jms.jar
to /WebContext/WEB-INF/lib, then add them into Project (Project -> Properties -> Java Build Path -> Add External JARs).
After all, go through these steps:
close project
close Eclipse
open Eclipse
open project.
Good Luck!

From reading What causes java.lang.IncompatibleClassChangeError? it looks like IncompatibleClassChangeError - Means I probably have conflicting library versions on my classpath. I can't tell from the stack trace which class/library is being duplicated.
My POM looks like so:

If you're still here, thanks for reading.
What am I doing wrong?
Why won't CXF/Spring start, and how do I fix it?
UPDATE:
After running the debugger the offending class appears to be:
org.apache.cxf.ws.policy.AssertionBuilderRegistryImpl
which resides in cxf-rt-ws-policy-2.7.5
As far as I can tell though that's the only place for that jar and It's only included once.
JHades Update
When I initially ran the report Log4J and Log4J-extras were overlapping, so was
JavaMail-1.5 and geronimo-javamail_1.4_spec. I've resolved those uses.
report results:
>>>> Jar overlap report:
Total number of classes with more than one version: 0
Both Jhades and mvn dependency:tree -Ddetail=true inidicate that cxf-rt-ws-policy is 2.7.5 just like every other cxf jar version.

So I it turns out my IDE intellij-dea was messing up my build.
I thought that since I had maven configured, that it would just be running pure maven, under the hood.
In my IDE I had configured an installed Directory for Axis2-1.6.0 to be used before my maven dependencies. Axis-2 was left over from an OLD version of my application and held duplicates of a lot dependencies including something called Neethi, which I've seen listed else where as a potential source of this error with CXF.

It seems the version of class org.apache.cxf.ws.policy.AssertionBuilderRegistryImpl that is being loaded is invalid.
You can check the WAR to see if there are any duplicate classes using this command (from JHades, a tool I've made), see here for the duplicate classes report:
java -jar jhades-standalone-report.jar path/to/war/webapp.war
The report should give something like this:
>>>> Jar overlap report:
poi-3.5-FINAL-20090928.jar overlaps with poi-3.7-20101029.jar - total overlapping classes: 990
xercesImpl-2.7.0.jar overlaps with xercesImpl-2.9.1.jar - total overlapping classes: 867
xalan-2.6.0.jar overlaps with xalan-2.7.1.jar - total overlapping classes: 711
bcel-5.2.jar overlaps with xalan-2.7.1.jar - total overlapping classes: 361
xml-apis-2.9.1.jar overlaps with xml-apis.jar - total overlapping classes: 301
jasperreports-applet-3.7.1.jar overlaps with jasperreports-javaflow-3.7.1.jar - total overlapping classes: 254
jasperreports-3.7.1.jar overlaps with jasperreports-applet-3.7.1.jar - total overlapping classes: 254
...
Total number of classes with more than one version: 6169
Also it's possible to query the classpath for all versions of the class and for the currently used version:
System.out.println("All versions of AssertionBuilderRegistryImpl:" + getClass().getClassLoader().getResources("org/apache/cxf/ws/policy/AssertionBuilderRegistryImpl.class"));
System.out.println("Currently used version of AssertionBuilderRegistryImpl:" + getClass().getClassLoader().getResource("org/apache/cxf/ws/policy/AssertionBuilderRegistryImpl.class"));
There are a couple of possibilities: either multiple versions exist, and only one is correct. In that case exclude the jars with the wrong versions in maven.
If only one version exists, then it's the wrong one, use mvn dependency:tree -Ddetail=true to find why it's included, and update the pom to load the correct version.
