RE: [wtp-dev] The Big Picture
|
One of my goal was to better understand the new
organization as specified by the project refactoring proposal, so using existing
features would not work for that since they have yet to be updated to reflect
this. Part of this process (at least as far as it applies to common) is to drive
the creation of new features.
So... If you look at the component listings in my
e-mail, you will notice that WST and JST parts co-mingle (just like they do in
the project refactoring proposal). Now, if under each of the new projects we
define a WST and a JST component and graph dependencies of those components,
then we would not end up with any cycles (the build works, as you point out). Is
that good enough? Is it ok to have cycles at project-level as long as we can
define components such as no cycles would exists? How would you build such a
structure once the codebase is re-organized based on the project refactoring
proposal? We wouldn't be able to have a project-level build since a top-level
driver would need to know how to weave builds of components of different
projects such that cycles are avoided.
The Java EE <-> Common cycle is due to
jst.common.frameworks depending on wst.web. This seems wrong to me. This builds
right now because by the time jst.common builds, all of wst has been compiled,
but I think jst.common should only be able to see
wst.common.

I'm not sure I understand, but if
you are saying that Common depends on Java EE, then I think something is amiss.
The way our build works, it wouldn't
compile if that was the case. Does
your analysis also take into account the WST/JST split? I think the way to approach this would be more along the
lines of our defined features? Or,
am I simply not understanding? thanks,

| [wtp-dev] The Big
Picture |

So in my quest to understand the "Common Project", I've been writing a
little utility that can analyze plugin dependencies and produce a
component-to-component dependencies (given component definitions). Until today,
I've been mostly focused on understanding how the rest of WTP depends on common,
but today I decided to let my utility show me the rest of the picture. Attached
is the result. I knew the dependency lines were not going to be clean, but I was a bit
surprised by the result. There are four simple circles that can be easily
spotted... Java EE <-> Common (yikes!) Java
EE <-> EJB Java EE <-> Server
Tools Java EE <-> Web Services
More complicated
circles are also present, but these are harder to spot. One example is Web
Services -> EJB -> Java EE -> Web Services. It strikes me that we either
have a lot of work ahead of us on refactoring the dependencies or these boxes
aren't quite right. Maybe a bit of both.
Thoughts? Does any of this come as a
surprise? I
used information found in http://www.eclipse.org/webtools/devProcess/wtpProjects/Refactor%20WTP%20Proposal.pdf as the definition of the component boundaries. I then ran my
utility against 3.0 M1 installation which included WTP SDK and WTP automated
tests. Let me know if the component membership as listed is not accurate and
needs to be tweaked. The only two plugins that are not accounted for are
org.eclipse.wst and org.eclipse.jst. Not sure where these would end up.
