I am moving an existing project (legacy) to maven. It has the following structure:
ParentProject
- EARModule
- src
- target
- pom.xml (ear)
- WARModule
- src
- main
- java
- (java packages and classes)
- resources
- dev
- index.jsp
- prod
- index.jsp
- webapp
- views
- index.jsp (original)
- WEB-INF
- target
- pom.xml (war)
- pom.xml (parent)
I intend to have two different profiles: production and development. In production profile, /WARModule/src/main/resources/prod/index.jsp should be assembled into views/ war directory. In development profile, /WARModule/src/main/resources/dev/index.jsp should be copied into views/ war directory.
For that, I am trying to make use of the maven-resources-plugin, which I am configuring in war pom.xml.
<properties>
<prodResourcesDir>${basedir}/src/main/resources/prod</prodResourcesDir>
<devResourcesDir>${basedir}/src/main/resources/dev</devResourcesDir>
<viewsDir>${basedir}/target/WARModule/views</viewsDir>
</properties>
<profiles>
<profile>
<id>development</id>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.6</version>
<executions>
<execution>
<id>copy_development_index.jsp</id>
<phase>prepare-package</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${viewsDir}</outputDirectory>
<resources>
<resource>
<directory>${devResourcesDir}</directory>
<filtering>true</filtering>
<includes>
<include>index.jsp</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
<profile>
<id>production</id>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.6</version>
<executions>
<execution>
<id>copy_production_index.jsp</id>
<phase>prepare-package</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${viewsDir}</outputDirectory>
<resources>
<resource>
<directory>${prodResourcesDir}</directory>
<includes>
<include>index.jsp</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
</profiles>
As you can see above, I am creating two profiles (production and development) and configuring the resources plugin under each of them.
When I run mvn install -P any_of_the_profiles, index.jsp is not copied to the specified destination. Instead, I get the original version. Can anyone help me sort this out?
Below the log trace:

I ended up figuring out that maven-resources-plugin works just fine for resources, not web resources (JSP).
So I switched my approach to the maven-war-plugin filtering feature and specifying the destination path. Thus, the profiles section in my web pom.xml ended up like this:
<profiles>
<profile>
<id>development</id>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.0.0</version>
<configuration>
<webResources>
<resource>
<directory>${devResourcesDir}</directory>
<filtering>true</filtering>
<targetPath>views</targetPath> <!-- target/WebModule/ subdirectory -->
<include>index.jsp</include>
</resource>
</webResources>
</configuration>
</plugin>
</plugins>
</build>
</profile>
<profile>
<id>production</id>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.0.0</version>
<configuration>
<webResources>
<resource>
<directory>${prodResourcesDir}</directory>
<filtering>true</filtering>
<targetPath>views</targetPath> <!-- target/WebModule/ subdirectory -->
<include>index.jsp</include>
</resource>
</webResources>
</configuration>
</plugin>
</plugins>
</build>
</profile>
</profiles>
This tells maven-war-plugin to move index.jsp from the specified resources directory to the target/WebModule/views directory. It is all done by the war plugin just before packaging the war, so there is no need to specify the life cycle phase.
