Question

I want to build an application distribution with Maven. I have a module in my project which holds the main source code. I decided to build the application distribution from this module. I’m telling maven in the module’s POM to copy all the configuration files and dependant libs to the target/ directory. My problem is that Maven keeps all the build related temporary dirs (like. classes, generated-sources, maven-archiver) in the target directory. I wan’t to auto delete these at least during the install phase. How can i achive this? If i put the maven-clean-plugin to the end of the build it looks like Maven always deletes the whole target directory, no matter who i’m trying to exclude files what i’m trying to keep.

try this in your pom

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.2-beta-4</version>
    <executions>
        <execution>
            <id>user_distribution</id>
            <phase>package</phase>
            <goals>
                <goal>attached</goal>
            </goals>
            <configuration>
                <descriptors>
                    <descriptor>src/main/assembly/dist.xml</descriptor>
                </descriptors>
            </configuration>
        </execution>
    </executions>
</plugin>

and here is the xml
