GWT 2.0 w/ IntelliJ IDEA 7.0.5

[Steve Sinai]

Up until now I've used Eclipse for writing occasional GWT apps, but
I'm not an Eclipse expert and am much more comfortable using Intellij
for development. I thought I'd see how well IntelliJ 7.0.5 works for
developing some toy GWT 1.7 apps, and except for a few warning
messages, it seems to works fine.

Then I gave GWT 2.0 a try with IntelliJ 7.0.5 to see what happens, and
got the error messages posted below when building a little, default
"Hello World!" program that had worked using GWT 1.7. In trying to
figure out the problem, I came across an old post somewhere that
suggested older versions of IntelliJ wouldn't work with later versions
of GWT, but it wasn't clear which versions numbers they were talking
about, or even if this was true. The errors below look to be XML
Parser-related, but I don't know if there's a way I can point to a
different parser, or if the problem is actually something else.

So my question is...is it possible to develop with GWT 2 using
IntelliJ 7.0.5? I'd rather not spend time on something that ultimately
turns out to be futile, and when I asked the question over on the
IntelliJ forum, I didn't get a response. Thanks.

If you really want decent IntelliJ GWT support, you should probably
upgrade to IDEA 9.0, which added explicit support for GWT 2.0 and GWT
1.7.

Thanks. At the moment, upgrading IntelliJ isn't an option, so it looks
like I get to hop around between two IDEs. Ugh!
