How to prevent unpack of dependencies in Java FX program

Question

I created a new Maven JavaFX program (I'm new to Java FX) in Netbeans the default POM tries to unpack dependencies to the /target/classes directory.

This is annoying because I have some pretty big dependencies (ie eclipse-link).

I have tried using using copy-dependencies instead and excluding the big dependencies but it's not find the classes.

Why did Netbeans build this POM, does Java FX need unpacked dependencies (for FXML, etc) ?

Answer 1

In your pom.xml, find the code below:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <version>2.6</version>
    <executions>
        <execution>
            <id>unpack-dependencies</id>
            <phase>prepare-package</phase>
            <goals>
                <goal>unpack-dependencies</goal>
            </goals>      
            <configuration>
                <excludeScope>system</excludeScope>
                <excludeGroupIds>junit,org.mockito,org.hamcrest</excludeGroupIds>
                <outputDirectory>${project.build.directory}/classes</outputDirectory>
            </configuration>
        </execution>
        <execution>
            <id>copy-dependencies</id>
            <phase>package</phase>
            <goals>
                <goal>copy-dependencies</goal>
            </goals>      
            <configuration>
                <outputDirectory>${project.build.directory}/classes</outputDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>

Please find the element name <excludeGroupIds>

and just add the groupId name,which you will find under <dependencies>.

groupId names should be comma(,) separated.
