Migrating from Mylar 1.0 to Mylyn 2.0

Follow these instructions to migrate from the Mylyn 1.0 to 2.0 APIs, noting that the project changed names during this period.

Bugzilla

Open each query that you have, select Update Attributes and change the product from Mylar to Mylyn.
Note that mylar-inbox@eclipse.org has been renamed to mylyn-inbox@eclipse.org.
After synchronizing you may see a large number of bugs with incoming changes. This is due to the product name having changed on those bugs. If you have too many incomings to read through, we recommend selecting resolved bugs and using Mark->Read via the context menu.

General

Mylar to Mylyn project name refactoring
- Use Search > File Search, enter in "org.eclipse.mylar" as search string and enter file types "*.java, *.xml, *.xsd, *.properties, *.mf" and click on Replace... at bottom of Search dialog. In resulting Replace dialog enter "org.eclipse.mylyn" as the replace text.
- Select all projects and execute Source > Organize Imports.
- If you get compile errors after Organizing Imports related to HttpClient ensure that the apache commons HttpClient (contained in org.eclipse.mylyn.web.core package) has been imported NOT the jvm's version.

Library dependencies have moved to org.eclipse.mylar

MylarStatusHandler and IStatusHandler
- moved from org.eclipse.mylar.context.core to org.eclipse.mylar.core

MylarStatus (place holder, will improve as we solidify this)
- MylarStatusHandler.displayStatus(dialog title, IStatus status) - call to display error and information dialogs
- When returning CoreException pass in a MylarStatus with appropriate code (see IMylarStatusConstants).
- If IMylarStatusConstants.INTERNAL_ERROR is sent to MylarStatusHandler.displayStatus an error dialog will appear and the error will be logged.
- IMylarStatusConstants.REPOSITORY_COLLISION used for mid-air collision. Pass repository url and appropriate dialog will be displayed.

WebClientUtil
- moved from ..mylar.tasks.core to ..mylar.core.net

Methods that do I/O operations now take an IProgressMonitor parameter (#143011)

Tasks API

Sorting is alphabetical.

AbstractAttributeFactory
- getIsReadOnly() renamed to isReadOnly

AbstractNewRepositoryTaskEditor
- handleNewBugPost() renamed to updatedSubmittedTask()

AbstractQueryHit
- setDescription(..) renamed to setSummary(..)

AbstractRepositoryConnector
- getLastSyncTimestamp(TaskRepository repository, Set<AbstractRepositoryTask> changedTasks): added (may change as part of bug#176934)
- getSupportedVersions() has been removed (#1768159)
- createTaskFromExistingId() is no longer abstract and takes care of task creation
- updateTaskFromTaskData(TaskRepository, AbstractRepositoryTask, RepositoryTaskData) added. Must be implemented to handle updating information on the AbstractRepositoryTask with data from the RepositoryTaskData
- renamed updateTask to updateTaskFromRepository
- createTaskFromExistingKey() renamed to createTaskFromExistingId() and is final
- makeTask() added. Connector specific repository task construction
- setTaskDataManager() added. Manager set upon connector construction in TasksUiPlugin. If being used headless, will need to manually set for offline support.

- getRepositoryType() renamed to getConnectorKind()

AbstractRepositoryConnectorUi
- openRemoteTask(String repositoryUrl, String id): removed, this method no longer needs to be implemented by the connector. Instead classes can rely on the new openRepositoryTask(..) method, and override it if necessary.
- getRepositoryUrl and all ID/URL methods: now final, change via setters
- + findHyperlinks(...) override to detect hyperlinks in editors
- handlesDueDates() added. Override and return true if connector capable of handling due dates.

- addHit removed
- removeHit removed (use methods from parent class AbstractTaskContainer)
- findQueryHit removed
- getHits() removde (is a AbstractTaskContainer so can call getChildren() )
- setCurrentlySynchronizing() rename to setSyncrhonizing()
- setLastRefreshTimestamp() rename setLastSynchronizedTimeStamp()
- getLastRefreshTimeStamp() rename to getLastSynchronizedTimeStamp()
- setStatus() renamed setSynchronizationStatus()
- getStatus() renamed getSynchronizationStatus()

AbstractRepositorySettingsPage validation changes.
- setNeedsValidation(boolean needsValidation) if true validate button will be visible

- constructor now requires taskId (now immutable)
- getIdentifyingLabel() -> getTaskKey()
- getLastRefreshTimeInMinutes(Date) removed
- no more static methods (use RepositoryTaskHandleUtil)
- Replace this idiom:

   String handleIdentifier = AbstractRepositoryTask.getHandle(repository.getUrl(), taskId);
   ITask task = TasksUiPlugin.getTaskListManager().getTaskList().getTask(handle);

- with:

   ITask task = TasksUiPlugin.getTaskListManager().getTaskList().getTask(repository.getUrl(), taskId);

- isDirty() and setDirty() removed
- isDownloaded() removed
- getTaskData(), setTaskData() removed
- isSubmitting(), setSubmitting() added

AbstractRepositoryTaskEditor
- attachContext() Added IProgressMonitor parameter (#143011)
- attributeChanged() Anything that needs to be saved must be in attribute form and passed to this method. Most if this is all done for you but if you override AbstractRepositoryTaskEditor.createCustomAttributeLayout() then you will want to ensure that attributeChanged is called upon editing. Utility method createTextField() handles this call.
- createLabel() Utility method added. It will put an '*' at the front of the label if the attribute has been modified. Eventually this will be applied upon editing but currently only happens after re-freshing or re-opening the editor.
- createTaskFromExistingId() Added IProgressMonitor parameter (#143011)
- handleNewBugPost() Added IProgressMonitor parameter (#143011)

- getAttachmentData() has been replaced by getAttachmentAsStream() which now returns an InputStream for reading the attachment data (#186070).
- uploadAttachment() Added IProgressMonitor parameter (#143011). Attachment properties are now passed as an object of type ITaskAttachment. This interface provides a createInputStream() method to create a stream for reading the data source (#186070).
