Re: [dtp-dev] Developing DTP 1.5 code

[Brian Payton <bpayton@xxxxxxxxxx>]

John,

It's not an enforcement, but one thing
that might help is to encourage developers to use the Plugin Development
"Target Platform" feature.  For example, I use Eclipse 3.3
as my IDE, but I have the Target Platform set to use Eclipse 3.2.  In
Preferences -> Plugin Development -> Target Platform, in the Location
field, browse to the Eclipse version you want to use as the target platform
for compilation.

By the way, unlike Eclipse 3.2, Eclipse
3.3 allows you to define a chain of target locations right in the Target
Platforms preference page, so you can set the base Eclipse, plus a product
build as the target platform; then you can keep only selected plugins in
your workspace if you wish.  That's one reason I use 3.3 as my IDE.
 (Prior to 3.3, to do the same thing you had to create a "target"
object in your workspace, then select it as a pre-defined target in your
Target Platform preference.)

Regards,
Brian

Larry,

Thanks, this is good info: committers should consider implementing Larry's
idea, which will cover us for the VM side of the equation.

John,

One way to enforce the Java version is to use project-level compiler
settings.  The settings are then checked into CVS.  That way
no matter what
JVM the developer is using, the code will be compiled at a 1.4 JVM level.
It is very easy to setup and once you have the settings set for one project
you can simply cut and paste them into the other projects, so you don't
have to use the UI to set it up for each project.  The settings reside
in a
project folder called ".settings".

Unfortunately, I don't have any ideas on enforcing Eclipse 3.2
compatibility.

Committers,

There's been some confusion about how to develop DTP 1.5 code in line with
the target environments we have adopted. Specifically, there have been
a
number of cases during DTP 1.5 where the build broke due to dependencies
on
either a 1.5 VM or Eclipse 3.3 being injected. Over the past couple of
weeks, these types of problems have become more common, and this is
worrying since we need clean builds with increasing frequency as the Europa
end-game proceeds.

In an attempt to explain what should be happening here, I have created
the
following Wiki page:

http://wiki.eclipse.org/index.php/DTP_1.5_Development_Environment

Please let me know if there are any questions or clarifications necessary.
