将Javafx应用程序与Maven捆绑在一起时不必要的依赖关系

Question

I am building a JavaFX application with maven, using the javafx maven plugin. Now when I execute mvn jfx:jar , it copies a lot of unnecessary jars into the resulting lib dir, like:

• ant-1.8.2.jar
• maven-antrun-plugin-1.7.jar
• maven-plugin-api-2.0.11.jar

and many more. So, it's basically everything I use for compiling the application - but it's certainly not needed for running it. I feel like I should add a <scope>compile</scope> somewhere in the POM, but the <plugin> element doesn't take one as child. How can I tell maven not to include the plugins I use for compilation in the lib directory created with mvn jfx:jar ?

Edit: here's the POM if it helps:

I'm the maintainer of the javafx-maven-plugin.

As far as I can see, there is nothing wrong with your pom.xml, maybe this already works when you upgrade the plugin-version to current 8.1.5 ?!

To make sure where some dependency come from, please call mvn dependency:tree , maybe it's your own dependency:

<dependency>
    <groupId>org.flyx.dsa.heldendokument</groupId>
    <artifactId>generator</artifactId>
    <version>0.1-SNAPSHOT</version>
</dependency>

What confuses me: why are you putting "pluginManagement" inside your build instead just "plugins"?
