How to get the content of a directory inside of WAR that is inside of an EAR that is inside of a ZIP? - maven

Question

I have the following :
WAR1 that has /images directory that contains : photo1.png, photo2.png
WAR2 that has /images directory that contains : photo2.png, photo3.png
WAR3 that has /images directory that contains : photo4.png, photo5.png
EAR1 that has WAR1 and WAR2
EAR2 that has WAR3
ZIP file that created by the Maven Assembly plugin that contains EAR1 and EAR2.
Now I need the following :
While creating the ZIP file by the Maven Assembly plugin, I need to create the directory /images inside of the ZIP file that contains the content of /images directory of every WAR file that is in the EAR that is in the ZIP.
Please, if not clear let me know guys, so I would give more details.
Thank you so much.

Answer 1

The first step is to create a separate module like mod-zip which contains the following pom which has dependencies to all the artifacts and the configuration for maven-assembly-plugin.
You have to change the parent to your parent approriately:
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>com.soebes.maven.multiple.artifacts</groupId>
<artifactId>parent</artifactId>
<version>1.0.4-SNAPSHOT</version>
</parent>
<artifactId>mod-zip</artifactId>
<packaging>pom</packaging>
<name>Mod: ZIP</name>
<dependencies>
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>mod-war1</artifactId>
<version>${project.version}</version>
<type>war</type>
</dependency>
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>mod-war2</artifactId>
<version>${project.version}</version>
<type>war</type>
</dependency>
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>mod-war3</artifactId>
<version>${project.version}</version>
<type>war</type>
</dependency>
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>mod-ear1</artifactId>
<version>${project.version}</version>
<type>ear</type>
</dependency>
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>mod-ear2</artifactId>
<version>${project.version}</version>
<type>ear</type>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<executions>
<execution>
<id>test</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<descriptors>
<descriptor>test.xml</descriptor>
</descriptors>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
Second you need an assembly descriptor which describes what you like to have which is a little bit tricky:
<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd">
<id>test</id>
<formats>
<format>zip</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<dependencySets>
<dependencySet>
<unpack>true</unpack>
<useProjectArtifact>false</useProjectArtifact>
<includes>
<include>${project.groupId}:*:war:${project.version}</include>
</includes>
<unpackOptions>
<includes>
<include>images/**</include>
</includes>
</unpackOptions>
</dependencySet>
</dependencySets>
<moduleSets>
<moduleSet>
<useAllReactorProjects>true</useAllReactorProjects>
<includes>
<include>${project.groupId}:*:ear:${project.version}</include>
</includes>
<binaries>
<outputDirectory>result</outputDirectory>
<unpack>false</unpack>
</binaries>
</moduleSet>
</moduleSets>
</assembly>
The tricky things is to go via two steps. First filter the artifacts having only the wars with the dependencySets and the unpackOptions which will filter out the images from them. And second you need to use the EAR modules by using the moduleSets.
