How to combine javafx-maven-plugin and maven-assembly-plugin? - maven

Question

I have a JavaFx project which I want to reduce to one jar file.
My pom contains a java-fx plugin:
<plugin>
<groupId>com.zenjava</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>8.1.4</version>
<configuration>
<mainClass>application.Main</mainClass>
<jfxAppOutputDir>${project.build.directory}/jfx/app</jfxAppOutputDir>
</configuration>
<executions>
<execution>
<id>create-jfxjar</id>
<phase>package</phase>
<goals>
<goal>build-jar</goal>
</goals>
</execution>
</executions>
</plugin>
and an assembly plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4.1</version>
<configuration>
<!-- get all project dependencies -->
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<!-- MainClass in mainfest make a executable jar -->
<archive>
<manifest>
<mainClass>application.Main</mainClass>
</manifest>
</archive>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<!-- bind to the packaging phase -->
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
When I call "mvn package" a single jar file is being build but it does not contain the jfx-jar file but contains some sort of "jar wihout jfx support"-version.
How can I tell the Maven Assembly Plugin to use the jar version from the jfx plugin (which is located in jfxAppOutputDir (../jfx/app/))?

Answer 1

Found the problem myself.
the jar file with the "no main manifest attribute"-error was created by maven-jar-plugin. But it is possible to configure it to omit that creation. If you are interested please take a look:"what-is-the-best-way-to-avoid-maven-jar"
the assembly plugin worked correctly. It was my fault. I thought that the assembly plugin creates a jar file with all dependencies including all resource files(all files from the resource folder). My mistake. "jar-with-dependencies" includes all jars belonging to the project, nothing more.
