My Operating System: MacOs Big Sur 11.4
JDK: openjdk-16.0.1
I want to make a .dmg or .pkg file using command mvn clean jfx:native, however, it doesn't work.
[ERROR] Failed to execute goal com.zenjava:javafx-maven-plugin:8.8.3:jar (jar) on project csgo-cfg-helper-client: Execution jar of goal com.zenjava:javafx-maven-plugin:8.8.3:jar failed: Plugin com.zenjava:javafx-maven-plugin:8.8.3 or one of its dependencies could not be resolved: Could not find artifact javafx-packager:javafx-packager:jar:1.8.0_20 at specified path /Users/hll/Library/Java/JavaVirtualMachines/openjdk-16.0.1/Contents/Home/../lib/ant-javafx.jar -> [Help 1]
Is it Java Version too high? jLink work well and generate module success.
How should i do? This is my first time to bulid a JavaFX project. I find the same question in stackoverflow, but no useful answer.Thanks for your help.
You seem to follow an ancient tutorial. Just start with the official docs and not some crap pulled from the internet. https://openjfx.io/openjfx-docs/ And for packaging you app have a look here: https://docs.oracle.com/en/java/javase/16/jpackage

I am building a mobile gluon javafx application. App runs fine in the jvm but not on mobile.
I found out that i had ClassNotFoundException when loading the FXML and discovered that it would not find java.net.URL(!!) The unfound classes were not present in the projet arm64_ios reflection files, but i somewhat expected that as i did not directly use those classes in the code. Unfortunately, gluon seems not to be able to parse the fxml to add known classes. But i disgress.
Just to validate the problem, i added this class name to my POM reflectionList. As expected, it would find it but block on an other one, then an other one, this was endless.
I check out that when i ran gluonfx:runagent, the missing classes were correctly added to src/main/resources/META-INF/native-image/reflect-config.json.
As per https://docs.gluonhq.com/#_jni_and_reflection , i added a META-INF/substrate/congif/reflectionconfig.json file that was a copy of the META-INF/native-image/reflect-config.json. That did not help.
I do not know why the runagent files are not used, i think i might have fumbled somewhere. I will be very grateful for any hint. Thanks.

Ok, now i found a solution, not sure i understood what happens.
Everything was caused by my resources includes. Not sure why/if i added them, not sure where they came from. It seems that configuring includes removes the default ones and that forbid the inclusion of the json files, and thus i had no other defined reflections than those that were found at compilation.
Removing the includes section of the POM and adding <nativeImageArgs>--allow-incomplete-classpath</nativeImageArgs> within the POM finally cleared all compilation blurps.
This post helped me for this last tip: Why is my JavaFX 17 Application not building with Gluon ? Logged as JNI / Reflection problem
Thanks José for coming by.
My Project structure is
parent
|---ejb-app.jar
|---restapi-app.war
|---ear-app.ear
I am using commons-beanutils to map the JavaEntity Bean to normal POJO class(DTO). The implementation of commons-beanutils is available inside ejb-app.jar.
Example: BeanUtils.copyProperties(destination, source);
My ear-app.ear aaplication packages the two modules such as ejb-app.jar & restapi-app.war. Below I have added pom.xml of ear-app.ear

Problem:
When I deploy my aaplication in RedHat JBoss EAP7 server, I am getting the following error:
Caused by: java.lang.ClassNotFoundException: org.apache.commons.beanutils.BeanUtils from [Module "deployment.ear-app-0.0.1-SNAPSHOT.ear.ejb-app-0.0.1-SNAPSHOT.jar:main" from Service Module Loader]
I am having issues getting maven to do a simple clean install I am getting the following error:
Failed to execute goal org.sonatype.flexmojos:flexmojos-maven-plugin:3.8:compile-swf (default-compile-swf) on project flex: Source file not expecified and no default found! -> [Help 1]
I was following the tutorial on this site: Adobe Developer Connection - Flex and Maven
I have all of my .as files located in: src/main/flex/ but the problem is that I don't have a Main class, these are all basically interfaces so I can't just choose one of them to be the source file.
I have Eclipse installed as well, and it is yelling at me for the plugin part of the POM, saying:
Multiple annotations found at this line:
- Plugin execution not covered by lifecycle configuration: org.sonatype.flexmojos:flexmojos-maven-plugin:
3.8:compile-swf (execution: default-compile-swf, phase: compile)
- Plugin execution not covered by lifecycle configuration: org.sonatype.flexmojos:flexmojos-maven-plugin:
3.8:test-compile (execution: default-test-compile, phase: test-compile)
So I am not sure if this is related or not, but I have tried to copy/paste the code from the link above verbatim but I still get that error and the guy never mentions anything about it, so perhaps it's just a bug in the maven plugin in Eclipse.
Here is my POM.xml file:

I am open to ANY ideas on how to get this to compile these .as files. Thank you!
Edit: Okay I figured it out. I changed the packaging from swf to swc and it works. So very sad.
I converted the package from swf to swc and it worked like a champ. Hopefully this helps someone in the future.
you need the configuration tag so flexmojos knows where to start the build. (default application, or main class)

And my folder structure is the prescribed PROJECT_ROOT/src/main/resources/db/migration/V1__Base_version.sql:
I get the error when, from the PROJECT_ROOT, I execute:
mvn flyway:migrate
Don't forget to call compile first, to make sure the resources are copied over.
In my case I had to explicitely set
flyway.locations=classpath:db/migration
in my application.properties (Spring Boot) for it to work.
in my case this error was caused as package with name db.migration was created
instead of db -> migration
It has to be compiled:
mvn compile flyway:migrate
You may use
<executions>
<execution>
<id>compile</id>
<phase>compile</phase>
<goals>
<goal>migrate</goal>
</goals>
</execution>
<execution>
<id>clean</id>
<phase>clean</phase>
<goals>
<goal>clean</goal>
</goals>
</execution>
</executions>
in
<plugin>..</plugin>
and then just mvn compile is needed for execution of migrate task
In my case IntelliJ Idea created a folder db.migration instead of two separate folders db and migration inside
Execute mvn command from directory where target dir is located.
There is a maven based project, which can be built by maven install, but throw exception when run the out jar:

When running your Jar with java -jar, you're no longer running with the maven resolving of dependencies. You have to make sure that all the jars you depend on are available at the relative loacation specificied in the MANIFEST.mf file in your Jar. Usually, you would use the assembly plugin to create a distributable archive that creates this structure. Or you could use a uberjar/onejar plugin to included everything inside your Jar.
You have 2 options to fix this:
Option 1 - use both plugins below to copy dependencies to a "lib" folder (see outputDirectory) and make your Runnable JAR know where they are (see classpathPrefix)
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>example.MyMainClass</mainClass>
</manifest>
</archive>
</configuration>

<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
Option 2 - Use maven-assembly-plugin to create a single JAR with all dependencies included. (all dependencies are extracted and compressed together in the same JAR)

I've seen the problem, too. Cobertura creates instrumented copies of all compiled classfiles (in target/classes) by bytecode manipulation. My jar file contained the instrumented class files (from target/generated-classes/cobertura), but cobertura.jar was missing. So, ClassNotFoundException was the right reaction.
However, since my POM doesn't contain any hint, which are the intended classes for packaging, Maven has the free choice ... and it uses the instrumented set of files.
My solution was really simple: mvn clean and mvn package. The first call removes all instrumented classes. Then, the second call finds only the uninstrumented classes without any external references to Cobertura.
