----------------------------------
This project has moved from Jira to GitHub Issues. This issue was migrated to
[apache/maven-scm#506|https://github.com/apache/maven-scm/issues/506].
> Improved support for SCM providers like ClearCase that do NOT check out
> directly into the check-out-dir but into sub-directories of the check-out-dir

> As discussed on
> http://www.nabble.com/Towards-full-ClearCase-integration-tf3433039.html
> PROBLEM:
> The ClearCase implementation of the checkout command for ClearCase creates a
> ClearCase snapshot view. Such a snaphsot view is very similiar to a CVS or
> Subversion checkout directory, but one major difference is the directory
> structure. To make it clear, consider the following example:
> Consider you have checked out the project MY_VOB/my/project to
> d:\continuum-work\167:
> - When working with CVS or SVN, you would find the POM file at
> d:\continuum-work\167\pom.xml.
> - With ClearCase, the location would be
> d:\continuum-work\167\MY_VOB\my\project\pom.xml. This means that the
> directory structure within the configuration management system, is repeated
> in every view (checkout directory). AFAIK it is not possible to change this
> ClearCase behaviour.
> This leads to the following problems:
> - After adding a project to Continuum, the build cannot be performed because
> the POM file cannot be found. The build definition has to be changed
> manually, so that the POM file location is e.g. "MY_VOB/my/project/pom.xml"
> instead of "pom.xml".
> - The maven-release-manager performs a clean checkout from a tag to the
> target/checkout directory, and then runs the build in that checkout
> directory. Same problem here, it would have to be run in e.g.
> "target/checkout/MY_VOB/my/project" instead of just "target/checkout".
> SOLUTION:
> The solution is to add an attribute to CheckOutScmResult that contains the
> path of the project directory relative to the checkout directory. By default,
> and for most SCM providers, it is just "". But the ClearCaseCheckOutCommand
> sets e.g. "MY_VOB/my/project" instead. (Notice that this is only be possible
> with auto-generated config specs as introduced by SCM-287).
> PATCH:
> The attached maven-scm-patch.txt contains a patch to maven-scm-api,
> maven-scm-provider-clearcase and the BootstrapMojo in maven-scm-plugin. I
> tested it by trying scm:bootstrap for ClearCase (works now) and SVN (still
> works).
> After applying the patch, please deploy a new maven-scm snapshot version to
> the Apache Snapshot repo as well.
> Continuum and the maven-release-manager will have to be changed to pay
> attention to this relative path attribute accordingly; I will try to submit
> patches in the next days, at least for maven-release-manager. Should these
> patches be part of this issue, or should separate issues be created for these
> projects?
