Example #1 - Merge using default merger (parallel merger):

<build>
    <plugins>
        <plugin>
            <groupId>com.carmatechnologies.maven</groupId>
            <artifactId>properties-files-maven-plugin</artifactId>
            <executions>
                <execution>
                    <goals>
                        <goal>merge</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>

                    <operation>
                        <targetFile>${basedir}/target/merged.properties</targetFile>
                        <sourceFileSets>
                            <sourceFileSet>
                                <directory>${basedir}/src/main/resources</directory>
                                <includes>
                                    <include>a.properties</include>
                                    <include>b.properties</include>
                                </includes>
                            </sourceFileSet>
                            <sourceFileSet>
                                <directory>${basedir}/src/main/resources/env</directory>

                        </sourceFileSets>
                    </operation>
                </operations>
            </configuration>
        </plugin>
    </plugins>
</build>

Example #2 - Merge using simple merger:

                <operations>
                    <operation>
                        <targetFile>${basedir}/target/merged.properties</targetFile>
                        <sourceFileSets>
                            <sourceFileSet>

                        <filtering>true</filtering>
                        [...]
                    </operation>
                </operations>
            </configuration>
        </plugin>
    </plugins>
</build>

Example #4 - Fail on missing input properties file:

<build>
    <plugins>
        <plugin>
            <groupId>com.carmatechnologies.maven</groupId>
            <artifactId>properties-files-maven-plugin</artifactId>
