GWT 2.5.1-rc1 available

[Matthew Dempsky]

Hi everyone,

We're excited to announce the GWT 2.5.1-rc1 release candidate!  There will be an announcement soon on the GWT Blog, and you can download it here.  This release candidate has been uploaded to Maven Central with the version string of "2.5.1-rc1".

GWT 2.5.1 contains over 50 new bug fixes, many of which were contributed by the community.  Thanks to everyone who reported issues and/or submitted patches.

Please test out this release candidate and let us know of any issues, especially any regressions from either 2.4.0 or 2.5.0.  Thanks!

-Matthew, on behalf of the GWT team

While it's good to get rid of long-deprecated things, is it really a good idea to do that in a point release like this? Shouldn't it wait until GWT 2.6? I'm thinking in particular of GWTShell and GWTCompiler.

GWTShell and GWTCompiler have been deprecated since GWT 1.6, first released 3 years ago (1.6.0 is dated Feb 4th)

HostedMode was the replacement for GWTShell in GWT 1.6 and has disappeared long ago, replaced by DevMode (there's still a HostedMode entry point, but it simply says "hey, I'm deprecated, use DevMode instead" and exits: that was in Sept/Oct 2009 !)

GWTShell survived HostedMode only because JUnitShell was still based on it for a while (until April 2010, when it was rewritten to extend DevMode instead, and thus use Jetty instead of Tomcat).

Removing GWTShell was a long-overdue task, we're just removing clutter here. This allows us to remove the Tomcat dependency and stop bundling it into gwt-dev.jar (which almost balances the growth of ICU, so that gwt-dev only grows by  1MB instead of ~3MB)

So if you ask me, yes, it's a good idea doing this even in a point release.

Not ready yet (as well as the announcement on the blog).

Have a look here https://code.google.com/p/google-web-toolkit/issues/list?can=1&q=Milestone%3D2_5_1+status%3AFixedNotReleased

And the commit log should be (more or less): https://gwt.googlesource.com/gwt/+log/306af3a..2.5.1-rc1 

[Juan Pablo Gardella]

Thanks Thomas!

I tried upgrading from 2.5.0 to 2.5.1 but I am getting an error during the gwt compile.  I googled that I needed to remove my gwt-junitCache, which I tried but it doesn't seem to be helping.  I am still using the 2.5.0 gwt maven plugin since the 2.5.1 is not available.  Could that be causing the problem?  Thanks.

Deleting gwt-unitCache solved the issue for me. I have also deleted war/<appname> and war/WEB-INF/deploy but I think thats not needed.

Can you compile through Eclipse using GPE? I don't think the maven plugin itself is causing the problem. Maybe you still have a gwt-unitCache folder lying around somewhere that you haven't found/deleted yet?

I deleted all my target/war directories, but it is still not working.  I don't have an easy way to compile with eclipse.  I will wait until there is a gwt maven plugin and try again.  Thanks.

Added a checkbox to automatically scroll the log.

I've been waiting so long for this!

Sincerely,

Joe

This issue is open since August 2011. Is it a trivial fix, why is not being included in 2.5, 2.5.1?

Sorry, what issue are you referring to?

Sorry, I wasn't aware of that issue when we were triaging bugs for 2.5.1, and there wasn't a patch readily available so it didn't get prioritized.  If you want to make sure it gets fixed in the next release, the best thing to do is upload a patch to either gwt-code-reviews.appspot.com or gwt-review.googlesource.com.

Please read first comment in the issue:

This issue still exists in the final version (2.4.0).  It's a very easy fix.  Simply edit com.google.gwt.activity.shared.Activity and replace line 18 by the following:

import com.google.web.bindery.event.shared.EventBus;

It's not as easy as it sounds: this is a breaking change. Changing the Activity interface that way breaks every subclass.

It'll be done in due time, when totally retiring the com.google.gwt.event.shared.EventBus, but no sooner.

This happens if you have an older version of a gwt-x library in your classpath. 

It actually happened to me because the gwt-bootstrap version I used had a dependency to an old gwt-codeserver-1.5.0.jar version.  This dependency was removed in a latter gwt-bootstrap snapshot. 

Run  mvn dependency:tree -Dverbose on your gwt app and check if there any references to an older gwt version. 

Regarding gwt-maven plugin. Yes it is still version 2.5.0 but you can use newer GWT SDKs (http://mojo.codehaus.org/gwt-maven-plugin/user-guide/using-different-gwt-sdk-version.html)
