Please suggest how to fix this.
You have to add below configuration parameters to your flink-conf.yaml file.
classloader.parent-first-patterns.additional: org.apache.flink.statefun;org.apache.kafka;com.google.protobuf
jobmanager.scheduler: legacy
https://ci.apache.org/projects/flink/flink-statefun-docs-release-2.0/deployment-and-operations/packaging.html#flink-jar --> Official document says:
The following configurations are strictly required for running StateFun application.
classloader.parent-first-patterns.additional: org.apache.flink.statefun;org.apache.kafka;com.google.protobuf
We need to add this jar
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>statefun-flink-distribution</artifactId>
<version>2.1.0</version>
</dependency>
Package a statefun job to submit to an existing Flink cluster deployment style is no longer mentioned in statefun 3.1 documents. Is this deployment style still possible or supported? If so, where should the module.yaml file be packaged?

I have added io.quarkus:quarkus-camel-core to my application, but the direct start does not work within native-image. If I run quarkus in JVM, then it works.
There are projects in Github (https://github.com/apache/camel-quarkus/tree/master/extensions/direct) that somehow indicate that there is an extension planned in future, but it is not officially supported.
How can I make it run with minimal effort, e.g. create own extension project only for direct. If I am adding the existing projects to my Maven pom, I am getting problems with the different Maven coordinates, and at the end the native build tells me that there are duplicates.
What would be a good way to make the "direct" statement from Camel run in quarkus?
By the way, the native build works, i.e. I get an executable, but the injection of the direct statement does not work:
"org.apache.camel.ResolveEndpointFailedException: Failed to resolve
endpoint: direct://init due to: No component found with scheme:
direct"
Sources:
REST endpoint:
#Path("/hello")
public class GreetingResource {
#GET
#Produces(MediaType.TEXT_PLAIN)
public String hello() {
ExchangeBuilder exchangeBuilder = new ExchangeBuilder(context);
Exchange out = template.send("direct:init", exchangeBuilder.build());
return out.getOut().toString();
}
CamelRouteBuilder:
public class CamelSyncRouteBuilder extends RouteBuilder {
static final String HTTP_ROUTE_ID = "http:camel";
static long[] times = new long[1];
#Override
public void configure() throws Exception {
from("direct:init").routeId(HTTP_ROUTE_ID)
.setHeader(MyOrderService.class.getName(), MyOrderService::new)
.setHeader(Filler.class.getName(), Filler::new).process(fill(Filler.class.getName(), "fill"))
.split(body().tokenize("#"), CamelSyncRouteBuilder.this::aggregate)
.process(stateless(MyOrderService.class.getName(), "handleOrder")).end().to("log:foo?level=OFF");
}

the direct component should work out of the box even without a dedicated extension, as example it is used to create the integration test for the jdbc component (https://github.com/apache/camel-quarkus/tree/master/integration-tests/jdbc).
Can you share more information about your project and set-up ?
I was facing the same problem because i didn't learn how exactly Camel works. As it said in logs - you have no Component that provides "direct" URI. So you have to add that Component. There is one in Camel Quarkus extensions:

I made a project that is 6GB size. I'm trying to build a .JAR file but I get this following error:

.jar file builds and runs well if one large folder is excluded or resized to ~3GB. It seems like something is wrong with ZIP64 archiving format and my project's pom.xml file

I'm newbie in OSGi world but I was able to do some Camel and OSGi bundles to do some tasks in a middleware. Everything I made since was a proof of concept, but now I want to refactor some part of my code and I start writing a OSGi bundle who will contain common functionalities shared among other OSGi bundles.
To make it clean, I decide to write comments and use javadoc to get sleek documentation, but I'm stuck with this error:
Error resolving version for plugin
'org.apache.maven.plugins:maven-javadoc-plugin' from the repositories
I was able to run javadoc for another Camel component;
We have a local repository with the dependency maven-javadoc-plugin in;
I add the dependency maven-javadoc-plugin to my project;
I'm running out of ideas why it doesn't work.
Maybe I'm wrong and I using OSGi bundle in a wrong way...

Ok, i finally found my response after digging more deeply in javadoc page (Javadoc documentation) and add these lines into the build section:

My code complies but when I try to run the DataNucleus enhancer, I am unable to get the post compilation step to complete. I presume I am missing a jar file but which one?? I have included the error and the pom.xml

I had the same problem and was able to solve it by comparing https://cloud.google.com/appengine/docs/java/datastore/jdo/overview-dn2 and http://www.datanucleus.org/products/accessplatform_3_2/jdo/maven.html
There might be a simple typo in Google's pom.xml snippet. As you can read on the DataNucleus page the maven plug-in will automatically use the latest available datanucleus core. To prevent this use:
<plugin>
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-maven-plugin</artifactId>
<version>3.2.0-release</version>
<configuration>
<api>JDO</api>
<props>${basedir}/datanucleus.properties</props>
<verbose>true</verbose>
<enhancerName>ASM</enhancerName>
</configuration>
<executions>
<execution>
<phase>process-classes</phase>
<goals>
<goal>enhance</goal>
</goals>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-core</artifactId>
<version>3.1.3</version>
</dependency>
</dependencies>
</plugin>
And the enhancer will work! So the difference is that Google used <artifactId>datanucleus-api-jdo</artifactId>
which wasn't necessary for me and of course it did not override the choice of the datanucleus-core version that should be used. Please also note that the plugin was renamed from maven-datanucleus-plugin to datanucleus-maven-plugin starting with 3.2.0-m2. So I also changed this to use the official 3.2.0-release.
Furthermore Google describes to use copies of the JARs found in appengine-java-sdk-1.9.21/lib/opt/user/datanucleus/v2 which are:
asm-4.0.jar
datanucleus-api-jdo-3.1.3.jar
datanucleus-api-jpa-3.1.3.jar
datanucleus-appengine-2.1.2.jar
datanucleus-core-3.1.3.jar
geronimo-jpa_2.0_spec-1.0.jar
jdo-api-3.0.1.jar jta-1.1.jar
But since I'm not using ant but maven I simply had to add this dependencies to pom.xml to be able to use JDO with DataNucleus with the versions explicitly supported by Google:
<dependency>
<groupId>javax.jdo</groupId>
<artifactId>jdo-api</artifactId>
<version>3.0.1</version>
</dependency>
<dependency>
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-core</artifactId>
<version>3.1.3</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-api-jdo</artifactId>
<version>3.1.3</version>
</dependency>
<dependency>
<groupId>com.google.appengine.orm</groupId>
<artifactId>datanucleus-appengine</artifactId>
<version>2.1.2</version>
</dependency>
BTW: I spotted another bug in the pom.xml as provided by the current appengine-skeleton-archetype. The maven goal "appengine update" failed because the appengine-maven-plugin tried to upload my application with version set to 1.9.21. This is obviously the version of the used GAE SDK and not the version of my app. And it fails because it violates the allowed format for version ids as allowed by GAE. The fix was to correctly set the version in the plugin configuration by adding the line <version>${app.version}</version> like this:
<plugin>
<groupId>com.google.appengine</groupId>
<artifactId>appengine-maven-plugin</artifactId>
<version>${appengine.version}</version>
<configuration>
<enableJarClasses>false</enableJarClasses>
<!-- Comment in the below snippet to bind to all IPs instead of just localhost -->
<!-- address>0.0.0.0</address>
<port>8080</port -->
<!-- Comment in the below snippet to enable local debugging with a remote debugger
like those included with Eclipse or IntelliJ -->
<!-- jvmFlags>
<jvmFlag>-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n</jvmFlag>
</jvmFlags -->
<version>${app.version}</version>
</configuration>
</plugin>
Have fun!
I have my project building properly, being able to generate metaclasses and run the bytecode enhancer. But it's SBT, not Maven.
In case you are interested, please have a look at
http://github.com/frgomes/poc-scala-datanucleus
My project works absolutely fine on the Google Server but I get a VerifyError:
java.lang.VerifyError: (class: org/restlet/ext/servlet/ServerServlet,
method: createServer
signature: (Ljavax/servlet/http/HttpServletRequest;)
Lorg/restlet/engine/http/HttpServerHelper;)
Incompatible object argument for function call
Through extensive Trial and Error, I found out, that I used the wrong Scala Version. I downgraded from 2.7.7 to 2.7.6 and everything works fine. As to why, I have no Idea. Maybe the Lift interop.
The resulting pom.xml (short version):
