Copying file from one project to another in maven

Question

I\'m working on a multi-module project. We\'re using the appCtx.xml from one module in few other modules.

Current issue is that they\'re not always in sync with each ot

You can do this with the maven resources plugin: copy-resources, something like:

<plugin>
    <artifactId>maven-resources-plugin</artifactId>
    <executions>
        <execution>
            <id>copy-appCtx</id>
            <phase>generate-resources</phase>
            <goals>
                <goal>copy-resources</goal>
            </goals>
            <configuration>
                <outputDirectory>${project.build.directory}/src/blahhere</outputDirectory>
                <overwrite>true</overwrite>
                <resources>
                    <resource>
                        <directory>../other_project/src/blah/blah</directory>
                        <includes>
                            <include>appCtx.xml</include>
                        </includes>
                    </resource>
                </resources>
            </configuration>
        </execution>
    </executions>
</plugin>

This copies a file from one project (colocated on the same source tree) as part of the generate-resources phase. You can adapt this to your needs.

This copying from one project to another may cause unstable builds if the projects aren't all built at once, but the above will work for projects which are always built together.
