Maven profiles: maven-antrun-plugin & maven-war-plugin interaction

Question

I have a Spring framework project with the following three files in src/main/webapp/WEB-INF:

project.propterties
project-servlet.xml
project-security.xml

I am trying to use maven profiles as follows to 'inject' the above mentioned files in the case of a prod build:

        <profile>
        <id>prod-build</id>
        <build>
            <plugins>
                <plugin>
                    <artifactId>maven-antrun-plugin</artifactId>
                    <version>1.7</version>
                    <executions>
                        <execution>
                            <phase>prepare-package</phase>
                            <goals>
                                <goal>run</goal>
                            </goals>
                            <configuration>
                                <target>
                                    <delete
                                        file="${project.build.directory}/${project.build.finalName}/WEB-INF/project.properties" />
                                    <copy file="src/main/config/prod/project.properties"
                                        tofile="${project.build.directory}/${project.build.finalName}/WEB-INF/project.properties" />
                                </target>
                            </configuration>
                        </execution>
                    </executions>
                </plugin>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-war-plugin</artifactId>
                    <version>2.3</version>
                </plugin>
            </plugins>
            <resources>
                <resource>
                    <directory>src/main/resources/prod</directory>
                </resource>
            </resources>
        </build>
    </profile>

The problem is by the time maven-antrun-plugin gets a chance to run, the war has already been packaged. The ant <target> does run and makes appropriate changes, but too late.

The command line:

$ mvn -Pprod-build clean install

mvn output:

Any pointers will be greatly appreciated.

Did you note this line

[INFO] Copying webapp resources [J:\work\workspace\FocusMVN\src\main\webapp]

What's going on ?

The maven-war-plugin copy the content of src/main/webapp (which contains your dev project.properties) to the war. And while doing this it replace the one just copied by the ant task.

What you can try is to exclude the project.properties from the fileset copied by the maven-war-plugin (since it was already copied by your ant task.)

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.3</version>     
    <configuration>
       <warSourceExcludes>WEB-INF/project.propterties</warSourceExcludes>
    </configuration>
</plugin>
