With new version of mojo (TCOMP-2102), the component-registry.properties is filed with artifact's snapshot detailed version (ie including timestamp) meanwhile the repository created uses baseVersion (ie  x.y.z-SNAPSHOT).
Thus, component-server on starter cannot find  artifacts in repository.
 

For instance, artifact  org.talend.components:jdbc-ee:car:component:1.33.0-20220507.091042-30 (1.33.0-SNAPSHOT) is stored in repository as

/opt/talend/connectors/org/talend/components/jdbc-ee/1.33.0-SNAPSHOT/jdbc-ee:1.33.0-SNAPSHOT.jar

but in registry we have :

jdbc-ee:=org.talend.components:jdbc-ee:car:component:1.33.0-20220507.091042-30

So, artifact 1.33.0-SNAPSHOT cannot be found.
