org.osgi.framework.BundleException: Unable to resolve: missing requirement: osgi.wiring.package; (osgi.wiring.package=org.json)

I'm a newbie of Java/ Karaf 4.0.9/ Maven/ Pom/ Camel, I'm unable to solve the issue
Json part in pom.xml file, Here I changed the many Json version, but no use.
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20151123</version>
</dependency>
Here I attached my Pom.xml file, I google it. And get the same issue in GSON but I don't know How can i fix the issue in felix.

How can I fix this?

Your build looks great. So as far as I can see you produce a valid bundle.
Now at runtime you have to provide all bundles your project depends on. The error message tells you that your bundle needs a package org.json. So you need to install a bunde that exports this package.
You can try with this package:
install -s mvn:org.json/json/20180813
You should also consider to create a feature file during the build that allows to install your code including dependencies in one go.

How to fix maven-packaged jar reporting 'Error: Could not find or load main class .\FormulaTelemetryApp-1.0-SNAPSHOT.jar'

I am trying to package my JavaFX application using Maven, running it using exec:java is no problem and running maven - package yields no errors. But when I want to execute the runnable jar it returns the error 'Error: Could not find or load main class .\FormulaTelemetryApp-1.0-SNAPSHOT.jar' where the second part is the jar I want to execute.
Beneath I included my POM, I already went looking for solutions, this is where I stumbled upon the maven-jar-plugin, but including that didn't solve the problem. I also tried cleaning the project and compiling/packaging again but that didn't change anything either.
As you might notice, I am fairly new to Maven (trying to self-learn it) so there might be some strange things in the POM.

As stated in the comments, the problem was two-fold: on one hand a fat jar was needed, maven-shade-plugin was used for that. Besides that a launcher class (non-application extending class) was needed as main class, as is stated in the answer to this question.

Lucene 6 error (cannot instantiate SPI class) in JAR file

I am trying to run my Java Maven project in a JAR file. It runs on IntelliJ IDEA 2017, however, when running it via the JAR file it does not run. The following error is shown:

I have seen similar problems in the other stackoverflow questions for example What causes err ' A SPI class of type lucene.codecs.Codec name 'Lucene42' but this also did not solve my problem.
My pom.xml is below. As you can see I tried also to use Resource Transformers, but it changed nothing.

Any help or guidance will be appreciated.

My solution was to use Maven Shade plugin and as I was using IntelliJ, the problem lied in how I was creating the JAR file.
Instead of creating it using 'artifacts' Build in IntelliJ, I created the JAR file using the 'mvn' tool in the terminal. Make sure your JAVA_HOME is correctly set. I had to install openjdk8 using apt-get again. In the end, the correct JAR file was created in the target directory.
See here for more details on how to create a JAR file using Maven Shade.
(This solution worked for Lucene 6.6.0, Windows 10 bash).

Spark runtime error: spark.metrics.sink.MetricsServlet cannot be instantialized

I got invocation target exception when running project with spark 1.3 lib in maven in IntelliJ.
I got met this error only in IntelliJ IDE. After I deployed the jar and ran via spark-submit, the error went out.
Any one has met with the same problem before? I hope to fix this problem so as to do easy-debugging. otherwise I have to package the jar every time when I want to run the code.
details are as below:

Strangely, I found the error didn't come out any more when I move the spark related dependencies to the front.
<dependencies>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-core_2.10</artifactId>
<version>1.3.0</version>
</dependency>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-mllib_2.10</artifactId>
<version>1.3.0</version>
</dependency>
//....the rest dependencies....
</dependencies>
So the sequence of the dependencies matters! Any one knows why?

I think the issue here is in jackson dependency. I had similar issue and problem was multiple jackson-core and jackson-databind versions. I think it is scala related issue. Anyway add this 2 jackson dependencies to pom with lower versions and it should work. Maybe you will not find right version from first try. This one works for me.

Jackson dependency issue - I had spark3.0.3-hadoop2.7 version, and had 2 versions of jackson annotation and databind jars. Removed those, and this error got solved.

Migrate existing Maven Project into an OSGI Bundle

i am new to the whole OSGi stuff and my task is to create an OSGi Bundle out from an exisitng maven project.
To get started i decided to pick the smallest part and starting with it:
Here is the pom.xml

I did some research and found the Apache Bundle Plugin for maven and changed the pom to this
<packaging>bundle</packaging>
and added
<build>
<plugins>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-SymbolicName>${pom.artifactId}</Bundle-SymbolicName>
</instructions>
</configuration>
</plugin>
</plugins>
</build>
mvn clean install went fine and i got a jar file containing the manifest, but of course the bundle could not be resolved
BundleException: The bundle "cross-main_1.2.12.SNAPSHOT [30]" could not be resolved. Reason: Missing Constraint: Import-Package: com.db4o; version="[8.0.0,9.0.0)
To make a long story short: What are the possibiliteis to migrate a maven application into an OSGi Bundle?
Espacially how to manage the dependencys

Probably all went well in the build. The maven bundle plugin automatically creates import package statements for all packages your bundle accesses. It even looks into blueprinnt and spring configs.
So the error message you get
could not be resolved. Reason: Missing Constraint:
Import-Package: com.db4o; version="[8.0.0,9.0.0)"
simply means that you need to install a bundle in your container that exports these packages. So ideally the db4o jar is already a bundle. Then you can simply install it. If not then you will have to create a bundle for it.
If you use apache karaf then you can make bundles on the fly by using the wrap: protocol from pax url which works for simple cases. If you need more then you can create a maven project to wrap the jar into a bundle. In most cases this is not necessary though.
I just checked the db4o download. It contains a db4o osgi bundle that you can install in your container.

Your maven file seems to be correct. This BundleException your'e getting:
BundleException: The bundle "cross-main_1.2.12.SNAPSHOT [30]" could not be resolved. Reason: Missing Constraint: Import-Package: com.db4o; version="[8.0.0,9.0.0)
Is because you have to import the appropriate packages in the bundle. For e.g. I have the bundle plugin:
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>2.3.7</version>
<extensions>true</extensions>
<configuration>
<archive>
<manifestEntries>
<Build-Change-Set>${changeSet}</Build-Change-Set>
<Build-Change-Set-Date>${changeSetDate}</Build-Change-Set-Date>
<Build-Location>${basedir}</Build-Location>
<Build-Machine>${env.COMPUTERNAME}</Build-Machine>
<Build-Date>${maven.build.timestamp}</Build-Date>
</manifestEntries>
</archive>
<instructions>
<Export-Package>my.bundle.main.package.*,
</Export-Package>
<Import-Package>
org.springframework.context.weaving,
org.springframework.aop,
org.springframework.aop.framework,
org.aopalliance.aop,
org.apache.cxf.bus.spring,
com.mycompany.mypackage.that.i.am.using.classess.from,
*
</Import-Package>
</instructions>
</configuration>
</plugin>
In your bundle plugin configuration add this section:
<instructions>
<Export-Package>your.bundle.main.package.*,
</Export-Package>
<Import-Package>com.db4o,
*
</Import-Package>
</instructions>
You can get more errors like this with the different packages missing. So make sure you add them all to your Import-Package section.
The other thing to notice is: You have to export your bundle's package if your'e using it in other bundles, and in those other bundles you have to import the package of your bundle.
