spring-boot maven maven-3 spring-boot-maven-plugin

running SpringBootTest using a spring profile given by maven

I got the following profile in my maven pom:

    <profiles>
        <profile>
            <id>local</id>
                <build>
                    <plugins>
                        <plugin>
                            <groupId>org.springframework.boot</groupId>
                            <artifactId>spring-boot-maven-plugin</artifactId>
                            <configuration>
                                <profiles>
                                    <profile>local</profile>
                                </profiles>
                            </configuration>
                        </plugin>
                    </plugins>
                </build>
        </profile>
    <profile>

which is fine for starting application, but if i want to build the application as follow mvn clean install -Plocal my @SpringBootTest fails due to:

No active profile set, falling back to default profiles: default

also tried:

        <profile>
            <id>local</id>
                <build>
                    <plugins>
                        <plugin>
                            <groupId>org.apache.maven.plugins</groupId>
                            <artifactId>maven-failsafe-plugin</artifactId>
                            <configuration>
                                <argLine>-Dspring.profiles.active=local</argLine>
                            </configuration>
                        </plugin>
                    </plugins>
                </build>
        </profile>

what am I missing?

ps mvn spring-boot:run -Plocal works no problem there ... also no intrested in mvn clean install -Dspring.profiles.active=local i know this works but just not intrested as profiles contain more than just profiles for us!

Solution

(Your) Spring-boot-maven-plugin (configuration) is not affected by "install" target (it involves only spring-boot:repackage, which is not aware of "active profiles"/this config), that is why your profile (though propagated) not activated in your tests.

If you want it to work for mvn install, you will have to pass:

-Dspring.profiles.active=local

to:

surefire-plugin

in pom(>profile>build>plugins):

<plugin>
  <artifactId>maven-surefire-plugin</artifactId>
  <configuration>
    <argLine>-Dspring.profiles.active=local</argLine>
  </configuration>
</plugin>

or via cmd. See also. Plugin-Doc.

failsafe-plugin ... analogous!;) Plugin-Doc.
maybe more... (any other plugin, which starts spring-boot.)

But of course, please don't "forget" about @ActiveProfiles, which activates(more precisely adds!) profiles to your test( classe)s. (but build independent;)

And (of course;) you can also "package" spring.profiles.active somewhere in your application (properties/any location), in (almost) any "maven build".

e.g. :

pom.xml:

 <profile>
  <id>local</id>
  <properties>
    <myProfiles>local,foo,bar</myProfiles>
  </properties>
 </profile>
 <!-- ... and (outside/in default profile!) -->
 <build>
  <testResources>
    <testResource>
      <directory>src/test/resources</directory>
      <filtering>true</filtering>
    </testResource>
  </testResources>
  <!-- ... -->
</build>

src/test/resources/application.properties:
```
 spring.profiles.active=${myProfiles}
```
would write into target/test-classes/application.properties:
```
 spring.profiles.active=local,foo,bar
```
..., which would be (hopefully) picked up & activated by the "next test".
