Maven: compilation module fails - maven

Question

I've these modules into my pom.xml:
<modules>
<module>rep-digital-common</module>
<module>rep-digital-api</module>
</modules>
So, rep-digital-common contains common classes rep-digital-api module needs.
When I compile them using
$ mvn clean compile
...
[INFO] rep-digital-common ................................. SUCCESS [ 7.571 s]
[INFO] rep-digital-api .................................... SUCCESS [ 17.988 s]
However, when I perform:
$ mvn -pl rep-digital-api clean package
it fails:
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 12.345 s

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile (default-compile) on project rep-digital-api: Compilation failure: Compilation failure:

[ERROR] symbol: class ContentStatus
ContentStatus symbol is located on rep-digital-common. I don't quite figure out what's going wrong.
Obviously, rep-digital-common is added as a rep-digital-api dependency:
<dependency>
<groupId>net.gencat.transversal.repositori.digital</groupId>
<artifactId>rep-digital-common</artifactId>
</dependency>
Any ideas?

Executing mvn clean compile or mvn clean package don't add the built artifacts in the local repository.
To add built artifacts in the local repository you have to use mvn clean install.
Note that as actually you build a reactor project, it works because the reactor provides dependencies needed to each current module to build.
On the other hand, as you compile rep-digital-api alone, the reactor will not help you :
mvn -pl rep-digital-api clean package
and so the compilation can only fail as rep-digital-common classes are not resolvable.
