Unable to bind maven profile to spring boot profile

Question

I've seen all the questions and post regarding this issue so please don't mark this as duplicate or route me to those issues, I have tried implementing those solutions but nothing worked as of now.

I have profile specific application.properties files i.e application-prod.properties, application-dev.properties, application-int.properties etc

pom.xml

<profiles>
    <profile>
        <id>prod</id>
        <properties>
            <activeProfile>prod</activeProfile>
        </properties>
    </profile>
    <profile>
        <id>int</id>
        <properties>
            <activeProfile>int</activeProfile>
        </properties>
    </profile>
    <profile>
        <id>dev</id>
        <properties>
            <activeProfile>dev</activeProfile>
        </properties>
    </profile>
</profiles>

    </plugins>

application.properties

spring.profiles.active=@activeProfile@

I'm doing mvn clean install -Pprod and then running the application. I'm sure the maven profile is executing during the build as I get this during the build

The following profiles are active:

 - prod (source: my-project-snapshot)

This is what I'm getting when running the application:

: The following profiles are active: @activeProfile@

Can anyone please help me here.

UPDATE when I close my IDE(STS) and do the maven build, it is working. Any info regarding this info would be really appreciated.

Answer 1

Have you enabled resource filtering in your pom.xml? Since you are using spring-boot this can be easily enabled, in your pom.xml

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
        </resource>
    </resources>
    …
</build>

UPDATE I have put all your plugins in a sample project's pom.xml also matching your spring-boot version:

<?xml version="1.0" encoding="UTF-8"?>

                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

When I run

mvn clean package spring-boot:run -Pdev -DskipTests

I see in the log files

com.example.demo.DemoApplication         : The following profiles are active: dev

And when I check the generated jar in target dir...target\demo-0.0.1-SNAPSHOT.jar\BOOT-INF\classes\ filtering has succeeded since in application.properties I get the line:

spring.profiles.active=dev

which in the source application.properties is

spring.profiles.active=@activeProfile@

So if you have a pom file similar to the above filtering should work.

Answer 2

Thanks a lot @pleft, I tried everything and because of that I realized this may not be a maven issue but an IDE issue. I'm using STS 3 and I found out that disabling "Refresh using native hooks" under Window > preferences > General > Workspace > Refresh using native hooks would solve the issue of STS IDE ignoring -P<profile> during maven build when STS is open.

There seems to be already a bug ticket for this.
