GWT 2.7 snapshot and Eclipse Plugin

[Matic Petek]

Hi,

 I would like to test new compile per file option, but we run our project from Eclipse and we don't use Maven. So I have perform the following steps :

1) Download JAR files from https://oss.sonatype.org/content/repositories/google-snapshots/com/google/gwt/

gwt-servlet.jar

gwt-user.jar

gwt-dev.jar

gwt-codeserver.jar

on 1.9.2014 date

2) Create new "Google" -> "Web Toolkit" configuration

3) select this configuration on my Eclipse project.

But when I run hosted mode, I get the error below. Any idea if I'm doing something wrong or Plugin (Kepler SR2, Google Plugin for Eclipse 4.3 3.7.0.v201407290035-rel-r43) is not update-ed with the latest version of GWT. Thank you.

Regards,

   Matic

For now, I can run my app in Eclipse hosted mode with GWT 2.6.1 and run SDM server with GWT 2.7 snaphost. It look nothing has change in GWT-RPC protocol so it is working.

I suspect the sdk isn't what you think it is if its not working. Can you check the classpath and see if it was updated? 

[Matic Petek]

I have superdevmode-launcher-legacy.jar in classpath and it is not compatible with GWT 2.7.

You shouldn't put never that .jar in your classpath.

GPE takes care of adding it to the launcher classpath when you run superdevmode and your gwt is not 2.7.

Manolo is correct, the  superdevmode-launcher-legacy.jar is not needed with GWT 2.7. It can be used with GWT 2.5.x and 2.6.x.

Did you add that to the classpath?

Yes, it was my mistake when I upgrade from 2.6 to 2.7 snapshot. Not it is working. I just want to write it in forum if someone else would have the some problem... Thank you for help.

Ah, thanks for sharing. I just wanted to double check. By the way if you're interested in the GPE preview, I've got that handy if you want to try it out. 

[Matic Petek]

Thank you for that, but right know my main target is to move our projects to GWT 2.7 and migrate our developers to SDM. 

Regards,

Hi Brandon,

The GWTP plugin has GPE as a dependency.  Can you send me a link to the preview please.
