---------------------------------
> Problems in Resolving Artifacts via Imports/Exports between Multiple

> Key: TUSCANY-3012
> URL: https://issues.apache.org/jira/browse/TUSCANY-3012
> Project: Tuscany
> Issue Type: Bug
> Components: Java SCA Core Runtime
> Affects Versions: Java-SCA-2.0
> Reporter: Mike Edwards
> Assignee: Mike Edwards
> Priority: Minor
> Fix For: Java-SCA-2.0
>
>
> The OASIS SCA Assembly tests which deal with Contributions and <import/> and
> <export/> statements in sca-contribution.xml files revealed problems in the
> way that artifact resolution is handled within Tuscany.
> When using more than 2 contributions, with imports and exports taking place
> between 3 or more contributions, exceptions can occur where resolving an
> artifact in contribution A follows an import to an export in contribution B.
> It can be that contribution B has not yet been resolved - and as a result the
> export class in B is not initialized for resolving the incoming resolve
> request from the export in A.
> The current code attempts to deal with this by ordering the resolution of the
> contributions. However, there are no clear criteria for the ordering,
> especially if different kinds of artifacts (eg composites, Java classes) are
> being imported from multiple locations and are resolved to different
> locations. As a result, the code is in practice unable to derive a
> resolution order that will work.
