Question

I’m trying to package a web application as a runnable JAR file with Maven. The jar-with-dependencies assembly takes care of including all the dependencies, but I still need to include src/main/webapp.

I managed to add the directory to my JAR with a custom assembly:

<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>webapp</id>
    <formats>
        <format>jar</format>
    </formats>
    <includeBaseDirectory>false</includeBaseDirectory>
    <fileSets>
        <fileSet>
            <directory>src/main/webapp</directory>
            <outputDirectory>/webapp</outputDirectory>
        </fileSet>
    </fileSets> 
</assembly>

And it does work, and it’s even possible to use this assembly together with jar-with-dependencies. However, the final JAR contains the webapp directory and all dependencies, but not the class files of my project. My assembly is apparently removing them.

Can I preserve the class files of my own project in an assembly? Or is there another way to add a directory to a JAR?

My assembly is apparently removing them

I’m guessing it’s the other way around, it’s not adding them.

Your class files are inside target/classes and they need to go inside target/webapp/WEB-INF/classes. I’m guessing you need another rule like this:

<fileSet>
    <directory>target/classes</directory>
    <outputDirectory>/webapp/WEB-INF/classes</outputDirectory>
</fileSet>
