Maven: How to print the current profile on the console? - maven

Question

I'm trying to print the current profile that is active running a build of a Maven Project.
I'm using the maven-antrun-plugin in order to print messages on the console, in combination with a property that refers to the current profile.
I have tried the following properties:
${project.activeProfiles[0].id}
${project.profiles[0].id}
But in both cases it prints the "string" as it is written, without resolving the variable.
This is my test:
<build>
<plugins>
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>generate-resources</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks>
<echo>current active profile: ${project.activeProfiles[0].id}</echo>
</tasks>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
But this is the result that I obtain:
main:
[echo] current active profile: ${project.activeProfiles[0].id}
Any suggestion will be appreciated.
Thanks.

Answer 1

The maven-help-plugin offers what you need. It has an active-profiles goal.
You can add it to your pom or even call it from the command line (include it in your maven build call). The How can I tell which profiles are in effect during a build? section of the Maven profile introduction page will show you how. In short:
mvn help:active-profiles
As this does not work for you (see comments) here is another solution:
I think the active profiles (there can be more than one!) are not propagated as available variables - but properties are.
So set a custom property in the profile section and use that, like
<profiles>
<profile>
<id>default</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<myProfile>default</myProfile>
</properties>
</profile>
<profile>
<id>debug</id>
<activation>
<property>
<name>debug</name>
</property>
</activation>
<properties>
<myProfile>debug</myProfile>
</properties>
</profile>
</profiles>
<build>
<plugins>
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>generate-resources</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks>
<echo>current active profile: ${myProfile}</echo>
</tasks>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>

Answer 2

you can add the maven-help-plugin in your pom to display always the active profile
<build>
<plugins>
<!-- display active profile in compile phase -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-help-plugin</artifactId>
<version>3.1.0</version>
<executions>
<execution>
<id>show-profiles</id>
<phase>compile</phase>
<goals>
<goal>active-profiles</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
