SCR Plugin and dependencies with classifier cause issue depending on the order
of dependency in pom.xml
-------------------------------------------------------------------------------------------------------
Key: FELIX-3070
URL: https://issues.apache.org/jira/browse/FELIX-3070
Project: Felix
Issue Type: Bug
Components: Maven SCR Plugin
Affects Versions: maven-scr-plugin-1.7.2
Reporter: Chetan Mehrotra
Priority: Minor
Here is the scenario. I have two modules
* ModuleA - It generates two artifact. One the main artifact and other a client
artifact which has classifier set to 'client' i.e.
** scr-bug:moduleA:jar:1.0.0-SNAPSHOT
** scr-bug:moduleA:jar:client:1.0.0-SNAPSHOT
* Module B - Has dependency on both artifacts.
Module A has a abstract service class which has Component 's componentAbstract
set to true. This class has a service reference entry i.e. a variable with
@Reference marked. Module B has a ExampleService which extends the
AbstractService and it has been marked aith Component annotation
Now when ModuleB has dependencies defined in order
# scr-bug:moduleA:jar:client:1.0.0-SNAPSHOT
# scr-bug:moduleA:jar:1.0.0-SNAPSHOT
Then SCR Plugin is able to locate the abstract component configuration and adds
dependency on the required service (referred in AbstractService). However if
the order is changed (i.e. classifier entry comes later) then SCR plguin
ignores the config.
I have also attached the debug log.
If you see scr-bug-log.txt (when dependency entry with classifier comes later)
then it has entries which indicates that dependency without classifier has been
ignored

Seeing the code of MavenJavaClassDescriptorManager then it uses
MavenProject.getArtifactMap() in the getDependencies method. It internally uses
org.apache.maven.artifact.ArtifactUtils.artifactMapByVersionlessId [1]. This
method only uses artifactId and groupId to create the map key and does not take
into account the classifier. So the getDependencies logic should use some other
method to obtain the depndencies
