Using Maven's shade plugin from Scala and sbt

Question

Due to some quirks in some dependencies, I'm having trouble with sbt-assembly, and have been told that people working with Java and have had good results with Maven's shade plugin.

How can I use Maven's shade plugin for Scala / sbt?

Elasticsearch shades a lot of artifacts in their Maven build. Have a look at that (search for "shade" for example usage). – Bolding

sbt assembly added support of shading in 0.14 – Syrup

You can add the following to your POM

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>1.6</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <filters>
                            <filter>
                                <artifact>*:*</artifact>
                                <excludes>
                                    <exclude>META-INF/*.SF</exclude>
                                    <exclude>META-INF/*.DSA</exclude>
                                    <exclude>META-INF/*.RSA</exclude>
                                </excludes>
                            </filter>
                        </filters>
                        <transformers>
                            <transformer
                                implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                <mainClass>com.group.id.Launcher1</mainClass>
                            </transformer>
                        </transformers>
                    </configuration>
                </execution>
            </executions>
        </plugin>
