I encountered a couple of unexpected problems when I upgraded my plugin for Eclipse (Helios) to v2.4 -- I finally got everything resolved, but I thought it might be worth sharing my experience.
1) The new plugin includes the ability to develop in GWT for Android native apps, but this introduces a new and unexpected dependency during the install: you have to also install the ADT plugin from http://developer.android.com/sdk/eclipse-adt.html (and then, in order to use the ADT plugin if you so desire, you need to install and link an Android SDK...). However, the ADK Plugin site is not on the standard software sources list for Eclipse, so you need to add it. Well, actually, you can either add the ADK plugin software site (and thus download and install the ADK plugin) or uncheck the Android GWT package when you upgrade the GWT plugin (but then you can't compile to native Android). I tried both ways, and they both work. 2) I had several projects which I had written using the GWT 2.3 plugin, and when I upgraded, they all started showing an error in the .../war/WEB-INF/lib/ directory. Oddly, I could still compile and run everything, but there was always this nagging error flag. It turns out that the appengine JAR files in those directories weren't updated as part of the upgrade. The newer, v1.5.4 JAR files need to replace the older, v1.5.2 JAR files. I had to do this by hand. I discovered the problem by starting a new project and comparing the contents of the directory with that in an older project. I hope this helps other people deal with upgrade issues. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
