Configurable outputDirectory for maven war plugin using Git

Question

I have put up a maven project on git repository which is using maven-war-plugin to create war directly in tomcat directory. But on different systems, tomcat directory path can be different.

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>2.3</version>
            <configuration>
                <outputDirectory><file-path></outputDirectory>
            </configuration>
        </plugin>

I want this outputDirectory parameter to be configurable without needing to change pom.xml on local systems.

Answer 1

I faced the exact same issue and I resolved it by putting the below plugin in my POM file.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.6</version>
    <configuration>
        <resources>
            <resource>
                <directory>${project.basedir}/src/main/resources</directory>                            
            </resource>
        </resources>
    </configuration>
</plugin>

As ali4j mentioned in comment, using env variable is appropriate solution for this scenario. Use a custom env variable in POM and ask the users to set the env in their system. How to refer environment variable in POM.xml?
