Errors in eclipse on gwt-user after cloning git

[Zied Hamdi OneView]

Hi Gwt friends :)

I wanted to start contributing to GWT, so I followed the instructions until I arrived to the point of using my eclipse.

There I have the following errors (and since I don't want to change code that I don't want to submit I'm kind of stuck in what to do now?). The errors are the following:

So the first set of errors is related to using java.util.Map in EntityProxies (which I thought is forbidden), but it may have changed in recent versions, or maybe this version in trunk. In that case I need to compile with GWT version that is in trunk right? The project compiles successfully with ant, do I have to use the freshly compiled GWT instead of my current 2.6.1 ?

com.google.web.bindery.requestfactory.vm.impl.TypeTokenResolver is a generated interface? I can't find it anywhere.

I also have a doubt with the task in eclipse/README.txt :

Project->Properties->Java Compiler->AnnotationProcessor->Factory Path

- Add Variable

- Select GWT_TOOLS and click Extend

- Select lib/requestfactory and the most recently dated

  requestfactory-apt-YYYY-MM-DD.jar

the only one with a date is requestfactory-apt-2011-08-18.jar (is it the last one???). There are two other versions without a date one seems old too 'apt-2.5.1' and the other doesn't specify its version

Thanks for your help

p.s:

if the error font is too small here they are again without formatting

I Just checked the jars in tools/lib/requestfactory

I looked inside the jar and the files are old: all of the jars contain files from 2011 (do I have to take a newly built file? where do I find it?)

See: https://groups.google.com/d/msg/google-web-toolkit-contributors/Ik4JOg-qIGk/PILkmFRz4gwJ

Some errors can be ignored because they are produced by the Google Eclipse plugin. The RequestFactory errors can be solved by using an updated requestfactory-apt.jar (so you need to build GWT once).

Someone of the GWT team should update the tools repo with that new jar.

(Thanks Jens :-) , I was writing this when I saw you replied)

So after browsing the forum posts I felt on this one that says we have to use the requestFactory-apt from the build/lib path. It's frustrating to have the README.txt misleading to a bad link as mentioned in 

Select project 'gwt-user'

Project->Properties->Java Compiler->AnnotationProcessor

- Check Enable project specific settings

- Check Enable annotation processing

- Optional: check Enable processing in editor (for on-the-fly

  validation of RequestFactory interfaces)

Can someone please change it to ease the process of contributing? (I still don't have the right to contribute: no answer from the electronic terms sign submission)

Also I have an issue in using the compiled GWT version as a GWT compiler: eclipse (sts) refuses to let me choose a GWT version (is this related to the .project file? or to my eclipse)

 After changing the apt, I still have this error, which is maybe justified by a bad commit...

You don't get a reply when using the online form at https://developers.google.com/open-source/cla/individual?csw=1

However I think you should/must sign the CLA through Gerrit at https://gwt-review.googlesource.com/#/settings/agreements . At least I did the online form first and later on as GWT switched to Gerrit + Git must redo it in Gerrit.

The GPE plugin has detected that you have a GWT trunk project in your workspace and uses that as GWT SDK no matter what. 

 

After changing the apt, I still have this error, which is maybe justified by a bad commit...

CSS file com/google/gwt/uibinder/test/client/Menu.css is missing WidgetBasedUi.ui.xml /gwt-user/core/test/com/google/gwt/uibinder/test/client line 110 Google Web Toolkit UiBinder Problem

Thats from the GPE plugin and can be ignored.

Perfect Jens :-),

Thanks a lot for all these valuable answers!!

I can get started now

[Thomas Broyer]

After you compile with Ant, select the requestfactory-apt.jar you just built for use in Eclipse (GWT_ROOT/build/lib/requestfactory-apt.jar)

We should definitely fix the instructions (feel free to provide the patch)
