Before Mylyn
Tasks scattered throughout web apps, code and pieces
of paper
No integration with IDE workflow

With Mylyn

.

Focused Workweek

With Mylyn
Too many tasks end up in your Task List

Personal planning
• Not everything will get done Monday morning, schedule/defer others
• Mesh with team planning activities

Focused workweek
• See only the tasks you need to work on

Working sets
• Discussed later

.

Scheduling Tasks
Schedule tasks via
• Editor Planning Tab
• Editor toolbar
• Click for Today
• Task List popup menu

Schedule for menu
• Today + 6 days into future
• ‘Someday’ This Week, Next Week, Two Weeks
• Choose Date… for date picker

Scheduled dates ‘float’
• Tasks scheduled for tomorrow that don’t get completed will
accumulate in Today’s bin
• Monday morning, re-evaluate, and re-schedule

.

Due Tasks
Set the due date on a task in the Planning
section of the task editor

• Not ‘floating’, remain fixed
• Appear red in Task List when overdue

• Synced to repository (if supported)

.

Focused Workweek
Focus on Workweek
• Scheduled, overdue, incoming/outgoing, completed
today. Can’t see a task? Use Find: field

.

Focused Workweek
Scheduled Presentation
• Focused / Unfocused
• Drag and drop scheduling

.

Focused Workweek
Progress Bars
• Task progress bars appear in the Task
List view when focused

• Progress bar also available in tooltip

.

Focused Workweek
Try it!
1. Use one of the scheduling mechanisms you’ve learned
about to schedule a number of tasks
2. One for Today, Wednesday, This Week, and Next
Week
3. Press the Focus on Workweek Task List toolbar button
4. Note that only tasks scheduled for the current week,
overdue or completed today are visible

5. Switch to the Scheduled Presentation
6. Drag the task scheduled for Today to Friday

.

Task Repository (Bugzilla, JIRA, Trac…)
Pros:
• Record of work to be completed (bug/enhancement)
• Threaded conversation related to bug
• Hub of collaboration (attachments, patches, etc)
• Some planning facilities (Due, Priority)

Cons:
• Takes developer out of IDE (often to your browser)
• No offline support
• Email inbox full of illegible change notifications
• Work artifacts (code) loosely associated through
patches

.

Mylyn Repository Connectors
Bring your bugs into Eclipse
• Communicate and Collaborate natively within your IDE
• Bugzilla, JIRA, Trac,… all become tasks in the Task List
• Rich editing, searching
• Change notification in the Task List where it should be
• Closes the gap: committed code linked to bug

Is my repository supported?
• http://wiki.eclipse.org/Mylyn/Extensions
• Ecosystem of Mylyn integrators growing

Two steps to repository tasks in the Task List
• Add Task Repository
• Create queries to bring in desired tasks

.

Add a Task Repository
Lets add a Task Repository
1. Task List view menu drop down > Show Task Repositories View
2. Click Add Task Repository button
3. Select Bugzilla Repository Type and press Next
4. Enter Server details
1. Server: http://mylyn.eclipse.org/econ
2. Label: Tutorial Repository
3. User ID: econ@econ.com
4. Password: econ (check Save Password)
5. Validate
6. Finish

Asked to create a Query… Yes please!

.

Define Queries
Queries are ‘active’. They will periodically
refresh, updating existing tasks in your Task
List and bring in new tasks that mach the
query.
Best Practices
• All tasks assigned to you
• All tasks not assigned to you but that you’re interested in
• Colleagues

Try it! - To Create a new Query:
• New Task drop down > New Query
• OR Right click in Task List > New > Query…

.

Define Queries
Each Repository Connector kind will have
differing yet very similar query parameters
• Upon pressing Finish, the
query will appear in your
Task List
• Tasks are retrieved from the
repository - synchronization

.

Synchronize
• Queries are synchronized (updated) on an adjustable schedule
from Window > Preferences > Tasks

• Task summary turns italic during synchronization

• Select and press F5 to manually synchronize tasks queries
• New Incoming Tasks (disable email notifications!)

.

Synchronize

• Open task to see new incoming changes

• Mark tasks as Read/Unread

• Hover to see changes in tootip
• Press Alt+Down to move to next unread task
• Press Alt+Shift+Down to mark as read and move
to next

• Unmatched Folders

.

Search
• Search without polluting your Task List
• Search > Search… (Ctrl+H)

• Group results by Owner (gold person is you)
• Filter completed
• Add to Category

.

Overview
• Integrated into your IDE
• Catch up and follow up offline
• Content cached locally
• Offline editing (@ 30,000ft and submit when back you land)
• Create new bugs offline and/or submit later
• Fast open (no waiting for round trip to server)
• Incoming changes highlighted (no illegible change
email)
• Rich editing features you’ve come to expect
• Spell checking
• Hyperlink to bugs and code
• Wiki formatting (even if repository support)

.

• Just like creating new Local Tasks
• Pick your repository
• Complete necessary fields
• Summary
• Product
• Component
• Description
• Submit (bottom of editor)
• Unsubmitted Folder

Try it!
• Submit a new bug now with a unique summary (your name)
• You will use this bug to complete the remainder of this tutorial
• Upon submitting, the task becomes a Repository Task, lets take a
closer look…
.

I’m using Mylyn…
My Task List has too many tasks!
Solution
• Use Mylyn’s Task Working sets to organize Task
List by role (i.e. Work, Personal )le ‘roles’:
Personal, Work,…

.

Task Working Set Switcher
• Select “Edit” to create new working sets
• Select a working set to only see tasks
and resources of that working set

.

Not just for your Task List!
• Scope Package Explorer to selected
projects
• Select projects and repositories to include
in the working set
• Speeds searches for large workspaces

Map Project to Repository
• Project properties > Task Repository
• Associate repository to make available
in working set dialog

.

Try it!
1. Set up an EclipseCon working set that contains the econ
repository tasks and one or two projects form your
workspace
2. Enable/Disable the working set
3. Note how the contents of both the Task List and
Package Explorer change

.

Information overload
Time wasted scrolling, browsing and searching, filtering
Constant multi-tasking causes context loss
Task context
• Mylyn monitors your interaction
• Creates degree-of-interest model
• Context is obvious and managed
• Tracks time spent on task
Task-focused UI
• View filtering, element decoration
• Automatic folding, content assist ranking
• Editor and perspective management
• One-click task switching
.

DEMONSTRATION

(watch to get the ‘idea’, then we’ll
help guide you through it)
.

Try it!
1. Schedule a task for Today
2. Activate the task using either the Task Editor’s
activate button or clicking in the Task List
3. Open the Task’s editor (if not already open)
and note the time spent on task
4. Update the estimate field if desired

5. Note that Package Explorer is vacant of any source artifacts
6. No need to panic, the code is all uninteresting and thus not visible
7. Unfocus the package Explorer using the focus filter button
8. Click on one or two files then re-apply the filter to see just these
files in the navigator

Continued…

.

9. With the focus filter now on, Alt+Click in some empty space within
the Package Explorer to temporarily expose all resources. Keep
holding down Alt and click on a few files you haven’t clicked yet
then release Alt key.

10. Note that the new items are now visible in the Package Explorer
since they are now part of your Task Context.

11. Press and hold the Alt key again and click
on a Class to dig deeper, exposing fields
and methods

.

12. Mark a method as a landmark, right click and select “Mark as
Landmark” – the method becomes bold

13. Open one of the files now visible

14. Close the file and note that that it is removed from the context
(settable via preferences: Window > Preferences > Tasks > Context)

.

15. Manually remove an element from your task context, right click and
select “Remove from Context” (any open editors will be closed)

16. Lets see how much time you’ve spent on this task so far. Check the
active time on the Task Editor’s Planning section.

.

DEMONSTRATION

context does not already exist.
3. To retrieve the context manually, right click the task in the Task
List and select Context > Retrieve

4. Once the context is retrieved, activate the task (if not already) and
note that the Package Explorer now reveals what elements the
context is concerned with.

.

Try it!
5. Open the task and view the Attachments section. Right click on
the Patch attachment and select apply.
