Maven assembly: generate a resource zip file and include it into the main assembly zip file -

how can proceed include generated zip file main zip file maven assembly plugin?

for example, have following folder structure:

./foldera/ ./file1 

and want generate zip file content this:

foldera.zip file1

here simplified config':

pom.xml

<?xml version="1.0" encoding="utf-8"?> <project >     <build>         <plugins>             <plugin>                 <groupid>org.apache.maven.plugins</groupid>                 <artifactid>maven-assembly-plugin</artifactid>                 <configuration>                     <appendassemblyid>false</appendassemblyid>                     <descriptor>${basedir}/assembly-zipfoldera.xml</descriptor>                     <finalname>foldera.zip</finalname>                 </configuration>             </plugin>             <plugin>                 <groupid>org.apache.maven.plugins</groupid>                 <artifactid>maven-assembly-plugin</artifactid>                 <configuration>                     <appendassemblyid>false</appendassemblyid>                     <descriptor>${basedir}/assembly.xml</descriptor>                     <finalname>${module-zipfinalname}</finalname>                 </configuration>             </plugin>         </plugins>     </build> </project>

===> config, maven complains can't find foldera.zip...

don't declare plugin twice; instead, need declare 2 executions of maven-assembly-plugin.

the first execution create first assembly , then, second execution use assembly create final one. both of executions bound package phase, , maven invoke plugin's execution in order of declaration in pom.

<plugin>     <artifactid>maven-assembly-plugin</artifactid>     <version>2.6</version>     <executions>         <execution>             <id>make-foldera</id>             <goals>                 <goal>single</goal>             </goals>             <phase>package</phase>             <configuration>                 <appendassemblyid>false</appendassemblyid>                 <descriptors>                     <descriptor>${basedir}/assembly-zipfoldera.xml</descriptor>                 </descriptors>                 <finalname>foldera</finalname> <!-- name without extension -->                 <attach>false</attach>             </configuration>         </execution>         <execution>             <id>make-assembly</id>             <goals>                 <goal>single</goal>             </goals>             <phase>package</phase>             <configuration>                 <appendassemblyid>false</appendassemblyid>                 <descriptors>                     <descriptor>${basedir}/assembly.xml</descriptor>                 </descriptors>                 <finalname>${module-zipfinalname}</finalname>             </configuration>         </execution>     </executions> </plugin> 

a couple of notes:

• the <finalname> should not contain extension, finalname of foldera produce archive foldera.zip after zip assembly made.

• the first assembly created inside build directory, target default. such, second 1 needs reference there with:

  <file>     <source>${project.build.directory}/foldera.zip</source> </file> 

  in assembly descriptor.

• since first assembly not final one, don't want attached, i.e. additional artifact produced project. can disable setting attach false. make sure last final 1 considered when deploying or releasing.

• descriptor deprecated parameter, should use descriptors instead.

with such configuration, running mvn clean package produce correct archive inside build folder.
