I have been trying to set up a JavaFX project to prepare for a school project and I wanted to use Maven to make it easier to share it as it removes the need for configuration as long as the pom.xml file is correctly written.
I can compile the project, run it with javafx:run but when I use the maven jar plugin to generate a JAR I get the following error trying to run it :
Error: Could not find or load main class org.openjfx.App
Caused by: java.lang.NoClassDefFoundError: javafx/application/Application
I don't understand why it's not finding the JavaFX classes as I do have the JavaFX Maven plugin as well as the javafx-controls and javafx-fxml dependencies added in the pom.xml
Here's the full file for reference

Does anyone know what I'm missing for the JAR to include the JavaFX classes ? I thought adding the maven plugin was enough.
Thank you
After I'd searched the net and similar StackOverflow questions and tried to apply the proposed sollutions I didn't come up with an idea how to fix this error, which gives me pom.xml:

I've had a look at .m2/repository and I've noticed, that there are files maven can't find. What should I do? What's the matter?
If there are files that maven can't find, you can always try to install the JAR file and going into
Project folder properties --> Java Build Path --> Add external JARs (Click on Modulepath if you cant immediately press Add External JARs)
I am learning Selenium and I would like to try add the maven-compiler-plugin to pom.xml and reimport maven settings. So I found this example to do it http://maven.apache.org/plugins/maven-compiler-plugin/examples/set-compiler-source-and-target.html and tried to add the code to the pom.xml. But the vrsion from the example 3.8.1 is red like on the screenshot. What it means? It is a copy from example.
Here is the whole pom.xml

In my case, I have changed the tags from plugin to dependency like it is in the Maven Repository.
<dependency>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.1</version>
</dependency>
In my case the groupId for the plugin was missing:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>
...
In my case, Spring Boot code works fine without changing anything, however, it gives the same error when I tried to commit in Git.
To solve this, I add the version info as follows and it worked.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>${maven-compiler-plugin.version}</version>
...
I've faced this issue with my old project (which was 100% working on my old ItelliJ IDEA) and newly installed ItelliJ IDEA:
in the pom.xml I had this:
<build>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.2</version>
<configuration>
<source>${java.version}</source>
<target>${java.version}</target>
</configuration>
</plugin>
</plugins>
</build>
And IDEA throwed an error maven-compiler-plugin not found. I've added
<groupId>org.apache.maven.plugins</groupId>
and IDEA found the plugin, and after that I was free to remove org.apache.maven.plugins without breaking IDEA
I got this error with IntelliJ. tried many ways, the below worked for me:
Close your IDE.
Delete "*.iml" and ".idea" -directories(present in the root folder of project)
Run "mvn clean install" from the command-line
Re-import your project into IDEA
In IntelliJ you can right click on 3.8.1 scroll down to Maven and select "Reimport". This solved the issue for me.
In my case, invalidating cache and restarting solved the issue.
Add the Following code in your pom the issue will resolve
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>

Make sure you are reimporting your dependency after adding plugins
I went to
.m2\repository\org\apache\maven\plugins\maven-compiler-plugin
and removed older version. It worked
You need to update your project so that the dependencies are updated from Maven side.
To update:
Change the file structure to project view.
Right click on project name -> Maven -> Reload project
And it will download all the necessary dependencies.
One reason could be due to proxy setup on your system in Maven settings.
You can remove/backup the previous maven settings.xml file and this should work.
mv ~/.m2/settings.xml ~/.m2/settings.xml.bak
I am developing a generic Spark application that listens to a Kafka stream using Spark and Java.
I am using kafka_2.11-0.10.2.2, spark-2.3.2-bin-hadoop2.7 - I also tried several other kafka/spark combinations before posting this question.
The code fails at loading StringDeserializer class:
SparkConf sparkConf = new SparkConf().setAppName("JavaDirectKafkaWordCount");
JavaStreamingContext jssc = new JavaStreamingContext(sparkConf, Durations.seconds(2));
Set<String> topicsSet = new HashSet<>();
topicsSet.add(topics);
Map<String, Object> kafkaParams = new HashMap<>();
kafkaParams.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, brokers);
kafkaParams.put(ConsumerConfig.GROUP_ID_CONFIG, groupId);
kafkaParams.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
kafkaParams.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
The error I get is:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/kafka/common/serialization/StringDeserializer
From Why does Spark application fail with "Exception in thread "main" java.lang.NoClassDefFoundError: ...StringDeserializer"? it seems that this could be a scala version mismatch issue, but my pom.xml doesn't have that issue:

Spark runs the program as by running an instance of a JVM. So if the libraries (JARs) are not in the classpath of that JVM we run into this runtime exception. The solution is to package all the dependent JARs along with main JAR. The following build script will work for that.
Also, as mentioned in https://stackoverflow.com/a/54583941/1224075 the scope of the spark-core and spark-streaming libraries need to be declared as provided. This is because some of the libraries are implicitly provided by the Spark JVM.
The build section of the POM which worked for me -

You need to use the Maven Shade Plugin to package the Kafka clients along with your Spark application, then you can submit the shaded Jar, and the Kafka serializers should be found on the classpath.
Also, make sure you set the provided Spark packages

My goal is to call a third party web service. So I generated the java classes from the wsdl using axis2 wsdl2java and adb data binding.
I'm calling the web service using these generated classes which works fine.
Now I want do do this in a bundle which is deployed on the osgi container apache karaf. I am building the bundle using the maven-bundle-plugin. Here I got the problem that karaf needs all those requirements of axis2 (axiom, mime4j, commons-fileupload,etc etc).
Is there any good solution to get axis2 to work on karaf besides deploying all those dependencies as bundles on karaf (because these are quite a lot)?

And the error I get in the karaf logs
[...]Unable to resolve 994.0: missing requirement [994.0] osgi.wiring.package; (osgi.wiring.package=org.apache.axiom.om)[...]
As I said I can solve this by deploying the axiom bundle but then it needs the next dependency which I could also deploy and so on...But as I said I want this to work without deploying numerous bundles manually.
