Building Incubator gen2 demos

[Isaac Truett]

Is there a mechanism currently in SVN for building the gen2 demos in
src-demo? I don't see shell scripts, batch files, etc. or anything in
build.xml. Is it BYOB at this point?

[John LaBanca]

BYOB for now, but let us know if you have trouble configuring it to run in your favorite IDE.  We'll probably have to add a build rule to the build.xml file at some point.

Thanks,

Also, I'm starting to add eclipse launch configs for the demos in
   trunk\eclipse-experimental\incubator-resources-windows
and
   trunk\eclipse-experimental\incubator-resources-linux

Thank you both! I'll see if I can get those launch configs running in
Eclipse. Everything compiles, but there's something amiss in my
runtime classpath.

[Emily Crutcher]

src-demo is a new source root that must be added if you are using your own launch configs.

If you are using the checked in launch configs, one change is that  GWT_HOME is assumed to point to a distribution, i.e. a gwt built with ant dist rather then ant build.

[Isaac Truett]

Yep. I added src-demo. My GWT_HOME points to
gwt-trunk/build/staging/gwt-windows-0.0.0

Trying to start DatePickerDemo I get this in the console:

com.google.gwt.core.ext.UnableToCompleteException: (see previous log entries)

Curiously enough, there is no previous log entry. The
UnableToCompleteException appears twice followed by:

The GWT shell complains about missing:

com/google/gwt/dev/jjs/intrinsic/Intrinsic.gwt.xml
com/google/gwt/emul/EmulationWithUserAgent.gwt.xml
and java.lang.Object (repeatedly)

I'm guessing the XML parsing is at the root of all this, so I'll dig
around there. If this rings any bells, though, I'd love to hear about
it.

[Emily Crutcher]

Nope, unfortunately not.Do the have any gwt-incubator demos up in eclipse or are they all creatively crashing?

[Isaac Truett]

DropDownListBox, SimpleWidget, and DatePicker demos all did the same
thing. Just for kicks, I hit "Restore Default Entries" on the
classpath tab, re-added src and src-demo as classpath entries, and now
they'll start. I don't know what the offending entry was. It must have
been inherited from another project, because that was the first time
that I directly modified the classpath for the launch configs.

Anyway, I'm up and running now. Thanks again!
