How to create password-protected zip in maven - maven

Question

currently I am using maven-assembly-plugin to create a zip file via "mvn clean package". The whole process works fine, the zip contains everything I need but a new requirement asks to create this zip file password-protected. I googled but not found any useful; is there anyone who needed to perform this task ?
Current plugin is defined in this way:
<build>
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<executions>
<execution>
<id>create-distribution</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<descriptors>
<descriptor>assembly/zip.xml</descriptor>
</descriptors>
</configuration>
</execution>
</executions>
</plugin>
</build>
and zip.xml is defined in this way:
<?xml version="1.0" encoding="UTF-8"?>
<assembly
xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2
http://maven.apache.org/xsd/assembly-1.1.2.xsd"
>
<id>zip</id>
<formats>
<format>zip</format>
</formats>
<fileSets>
<fileSet>
<outputDirectory>directory1/</outputDirectory>
<directory>directory1</directory>
</fileSet>
<fileSet>
<outputDirectory>/</outputDirectory>
<includes>
<include>config.properties</include>
</includes>
</fileSet>
</fileSets>
<files>
<file>
<source>target/data-jar-with-dependencies.jar</source>
<destName>data-jar-with-dependencies.jar</destName>
</file>
</files>
</assembly>

You must use an external program to unzip and zip the archive again. For example 7z:
7z e Unprotected.zip
7z a Protected.zip -pPASSWORD UNPROTECTEDFILENAME
If you want to integrate it in the build lifecycle then you need the maven exec-plugin to execute those two commands after the package phase.
