In a Spring Boot based project of mine I want to create two different builds from the same project.

The decision on which build is generated should come from a maven profile.

I want to create one build (full) which includes a certain folder src/main/java/com/example/demo/full and a certain dependency, and a second build (default or light) build which does not include them.

Including the dependencies for build full works, but I don't know how to make sure the folder src/main/java/com/example/demo/full is only compiled for the full build.

Here my pom.xml:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.3.RELEASE</version>
    </parent>

    <groupId>com.example</groupId>
    <artifactId>demo</artifactId>
    <version>1.0</version>
    <packaging>jar</packaging>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>

    <build>
        <finalName>demo</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <configuration>
                    <useSystemClassLoader>false</useSystemClassLoader>
                </configuration>
            </plugin>
        </plugins>
    </build>

    <profiles>
        <profile>
            <id>full</id>
            <dependencies>
                <dependency>
                    <groupId>org.apache.poi</groupId>
                    <artifactId>poi-ooxml</artifactId>
                    <version>3.16</version>
                </dependency>
            </dependencies>
        </profile>
    </profiles>

</project>

How can I manage to have the mentioned source-folder only compiled for profile full?

  • I would put the java packages which should be compiled only in on maven profile into a seperate source folder `scr/full-profile/java.....` and include it only in the specific profile. – matthias May 24 '17 at 12:27
  • Sounds good @matthias, but how to achieve this "inclusion" only for a specifc profile? – yglodt May 24 '17 at 12:35

Add a second src folder like scr\foo and then add a profile in maven configure this src folder.

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<build>
    ...
</build>

<profiles>
    <profile>
        <id>extraSource</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.codehaus.mojo</groupId>
                    <artifactId>build-helper-maven-plugin</artifactId>
                    <version>3.0.0</version>
                    <executions>
                        <execution>
                            <id>add-source</id>
                            <phase>generate-sources</phase>
                            <goals>
                                <goal>add-source</goal>
                            </goals>
                            <configuration>
                                <sources>
                                    <source>src/foo/</source>
                                </sources>
                            </configuration>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>

Here the source folder is added using the Build Helper Plugin plugin for maven. As it is embedded in the build section of the specific profile, it is only active while executing maven with this profile (see the activation section)

there are problem with disabling one of your maven-source-plugin if this dependency is a part of parent which you cant not give ID to, ill recomend to use phase none with this code to one of your pom.xml files that will disable this.

I also recommend to use command: mvn -Prelease-profile help:effective-pom to print if you have two of dependencies maven-source-plugin in your code, if yes, disable one of them with this code below:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-source-plugin</artifactId>
    <executions>
      <execution>
        <id>attach-sources</id>
        <phase>none</phase>
      </execution>
    </executions>
  </plugin>
