My friend Bevan has linked to the tools he referenced in his “Towards Maintainability” talk at the Wellington .NET users group recently.

I thought I’d add the equivalents from the perspective of an Eclipse-using Java developer… isn’t specific to a single programming language.
I simply type things into Google Chrome’s Omnibar.
FxCop & Gendarme
Visual Studio Class Diagrams
Perhaps AgileJ though I do not use it.
Snippets in Eclipse
Creating extensions to snippets
Maven 2
junit is integrated into all IDEs
Perhaps Doxia?
TeamCity supports java
Mylyn is probably the closest productivity adding, IDE-changing example.

Eclipse Galileo Improvements to Java Developer Tools

Here are some improvements to JDT Project in Galileo that I personally find useful:

  1. Support for {@inheritDoc} in the javadoc popups.
    • This is encourages its use, which in turn encourages documenting why a method has been overridden, or what’s so special about this particular implementation, without having to repeat the purpose of the method itself.
  2. Warnings when a method overrides a synchronized method, but isn’t synchronized itself.
    • It’s hard enough as it is to ensure you get the intended multi-threaded behaviour. This change can help prevent an error that while not very common, can be very hard to spot.
  3. When auto-reformatting an entire class, I can keep the line breaks that I’ve added.
    • This caters for where the formatting rules are too general, and are not aware that I’d find some things much clearer if split into multiple lines in very specific places.
  4. Constructor completion has been made more useful, by offering more appropriate suggestions.
    • I also often save myself some typing by writing the right hand side of the assignment, then using a quick assist to assign the result to a new variable.
  5. By holding down Ctrl, and hovering on a method, I can chose whether to jump to the declaration, or the implementation.
    • I still find this method of navigation difficult though, preferring to keep my hands on the keyboard, navigating to the method call, pressing Ctrl-T, and choosing which implementing or declaring class I wish to view. (That’s not a new feature.)
    • What I’d like is a companion for F3’s mapping of “Go To Declaration” that with a single key press I can “Go To Implementation”. However I can’t find that command in the key binding preferences page.

Eclipse Ganymede Features

The Eclipse Ganymede release is only a few weeks away. As a long time eclipse user, inquisitive, early adopter, I’ve been trying the milestone and release candidates of the java developer tools components. (Ganymede is a coordinated release of an enormous number of eclipse projects. Several packages are available here.)

The list of new features is no longer as easy to find, since it was linked to from the download page for the milestone releases, and since the releases are now release candidates, there are no new features.

These will no doubt be combined into a single what’s new page for the final release, but until then, the lists for each milestone release are well worth a read: M1 M2 M3 M4 M5 M6 M7

Update: As expected, the release of 3.4 is accompanied by a new New and Noteworthy page. What’s also worth reviewing is the feature comparison page for the various Ganymede packages.

My personal favourite dozen new features:

  1. System Proxy Settings – One less place to change those settings when I plug the laptop in somewhere new.
  2. Default console and file encoding – I develop on Windows for Linux.
  3. Shearing – I love the pun.
  4. The improved error log view, and the Plug-in registry view enhancements – these will help when trying out misbehaving plug-ins.
  5. Line support in overview ruler – much faster navigation.
  6. Runnable JAR export wizard – no more searching for and installing third party plug-ins to do this simple thing.
  7. Different highlighting for read and write occurrences of the selected or searched for element – this is fantastic.
  8. Direct interaction with text hovers – less hand movement is good. Being able to click through to other javadocs is fantastic.
  9. Breadcrumb navigation – this is a quite good compromise between ease of use and screen real estate.
  10. Support for external class folders – I haven’t used this yet, but can think of some past experiences where it would have been useful.
  11. Java compiler on multi-CPU machines – parallelisation is how we go faster these days.
  12. Quick Assist becomes even more helpful.

Eclipse’s quick assist feature saves a huge amount of work. There’s no need to go looking through menus and dialogs to find the right place to activate the thing you want to do right now, you simply hit Ctrl-1 and what you want to do is invariably in the short list that immediately pops up. The “what’s new” pages list these additional assists and fixes:

–    Helps with regular expressions in find/replace
–    Helps correct spelling in CVS commits
–    PDE Quickfix for Java file issues
–    Add @throws or @exception javadoc tag
–    Select a missing method error in the Problems view and Quick Fix
–    Create getter and setters for fields (encapsulate fields)
–    Extract method on expressions
–    Helps with the new SWT Templates
–    Helps with user created templates
–    Code completion helps with casts
–    Complete static members of not yet imported types
–    Ensure source entries found in are properly accounted for in the plug-in manifest
–    Diagnosis (and removal quick fix) of redundant superinterfaces
–    Improved key binding support
–    Convert to StringBuffer
–    Improved cursor jumping
–    New Javadoc tags to annotate (PDE) API with explicit restrictions
–    Quick fix provided for missing or incorrect @since tags
–    The Java problem hover now offers all available quick fixes
–    Use MessageFormat for string concatenation
–    Extract local variable (without replacing all occurrences)
–    only show templates applicable at the current location
–    Remove invalid use of API Javadoc tags
–    Inserting parameter name also shows guessed arguments
–    Shows gory details of improved text search
