    } catch (PatchException e) {
        assertTrue(e.getMessage().toLowerCase().contains("required patch 'prereq4b' is missing"));
    }
}

Example 2 with PatchException

use of io.fabric8.patch.management.PatchException in project fabric8 by jboss-fuse.

the class GitPatchManagementServiceImpl method listPatches.

@Override
public List<Patch> listPatches(boolean details) throws PatchException {
    List<Patch> patches = new LinkedList<>();
    File[] patchDescriptors = patchesDir.listFiles(new FilenameFilter() {

        @Override

    }
    return patches;
}

Example 3 with PatchException

use of io.fabric8.patch.management.PatchException in project fabric8 by jboss-fuse.

the class GitPatchManagementServiceImpl method trackPatch.

/**
 * <p>This method turns static information about a patch into managed patch - i.e., patch added to git
 * repository.</p>
 *
 * <p>Such patch has its own branch ready to be merged (when patch is installed). Before installation we can verify
 * the patch,
 * examine the content, check the differences, conflicts and perform simulation (merge to temporary branch created
 * from main patch branch)</p>
 *
 * <p>The strategy is as follows:<ul>
 *     <li><em>main patch branch</em> in git repository tracks all changes (from baselines, patch-management
 *     system, patches and user changes)</li>
 *     <li>Initially there are 3 commits: baseline, patch-management bundle installation in etc/startup.properties,
 *     initial user changes</li>
 *     <li>We always <strong>tag the baseline commit</strong></li>
 *     <li>User changes may be applied each time Framework is restarted</li>
 *     <li>When we add a patch, we create <em>named branch</em> from the <strong>latest baseline</strong></li>
 *     <li>When we install a patch, we <strong>merge</strong> the patch branch with the <em>main patch branch</em>
 *     (that may contain additional user changes)</li>
 *     <li>When patch ZIP contains new baseline distribution, after merging patch branch, we tag the merge commit
 *     in <em>main patch branch</em> branch as new baseline</li>
 *     <li>Branches for new patches will then be created from new baseline commit</li>
 * </ul></p>
 * @param patchData
 * @return
