maven zip uber-jar and shell script

You don't want to use the maven-assembly-plugin for creating the uber-jar. But you will want to use it to create that ZIP.

Currently, your maven-shade-plugin is bound to the package phase. You could shift that execution to the prepare-package phase (since it actually prepares your final packaging) add an execution of the maven-assembly-plugin bound to the package phase. Your assembly would create a ZIP based on the shaded JAR (which will exist since the shade plugin will have been executed) and the shell script.

A sample descriptor would be the following:

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3 http://maven.apache.org/xsd/assembly-1.1.3.xsd">    <id>your-id</id>    <formats>        <format>zip</format>    </formats>    <files>        <file>            <source>${project.build.directory}/projB-shaded.jar</source>            <outputDirectory>/</outputDirectory>        </file>        <file>            <source>/path/to/mvn_script.sh</source>            <outputDirectory>/</outputDirectory>        </file>    </files></assembly>

with the following POM configuration:

<plugin>    <artifactId>maven-shade-plugin</artifactId>    <version>2.4.3</version>    <executions>        <execution>            <phase>prepare-package</phase>            <goals>                <goal>shade</goal>            </goals>            <configuration>                <!-- current configuration -->            </configuration>        </execution>    </executions></plugin><plugin>    <artifactId>maven-assembly-plugin</artifactId>    <version>2.6</version>    <executions>        <execution>            <id>assemble</id>            <goals>                <goal>single</goal>            </goals>            <phase>package</phase>            <configuration>                <descriptors>                    <descriptor>/path/to/assembly.xml</descriptor>                </descriptors>            </configuration>        </execution>    </executions></plugin>

The typical location for the assembly descritor is under src/assembly as per the Maven standard directory layout.
