Ext GWT 3.0 Release Candidate is now available

This release candidate build is the culmination of a series of beta builds of Ext GWT 3.0. The release candidate includes a host of features, enhancements, and bug fixes. We've made many changes to solidify this release, and many of these changes were driven by discussions with the community in the Ext GWT Forums. Here are a few highlights:

• A new Desktop Example showing off customization of Ext GWT 3.0 components
• Generics updates to better support covariance and contravariance
• Documentation refresh
• API naming consistency updates
• Layout performance improvements
• CellComponent redraw optimizations
• Improved chart resize logic
• And over 140 bug fixes

Read more about all of these changes in the release notes.

Upgrading to the release candidate

Manual upgrade: As before, we have a zip archive available for download.


Maven: In your POM, update your dependency to version 3.0.0-rc.

Community feedback has been invaluable to us throughout the betas, and now we're eager to hear from you as you try out this release candidate build. We welcome your feedback on the Ext GWT Community Forums. The discussion forum is a great place to chat with other prerelease users of Ext GWT 3.0, and the bugs forum is the fastest way to bring a problem to the attention of our engineers.

Thanks for all your interest and involvement throughout the development of Ext GWT 3.0. We can't wait to finish up Ext GWT 3.0 so you can start using it to build the next generation of web applications.

Hello Darell

i changed the version of gxt in pom.xml from 3.0.0-beta3 to 3.0.0-rc, but it didn't work. The dependency looks like

 <dependency>
        <groupId>com.sencha.gxt</groupId>
        <artifactId>gxt</artifactId>
        <version>3.0.0-beta3</version>
    </dependency>

Can you maybe post the complete dependency .

[Colin Alworth]

According to maven's own search page, that should be correct - at http://search.maven.org/#search|ga|1...om.sencha.gxt" it lists all of the artifacts from 3.0.0-rc, and http://search.maven.org/#artifactdet...t|3.0.0-rc|jar shows that this is the correct dependency:

<dependency>
    <groupId>com.sencha.gxt</groupId>
    <artifactId>gxt</artifactId>
    <version>3.0.0-rc</version>
</dependency>

Make sure you are not in offline mode, and consider posting the log that shows that maven tries to download from http://repo1.maven.org/maven2/ and fails - this link correctly pulls down the jar for me http://repo1.maven.org/maven2/com/se...t-3.0.0-rc.jar

I encounter the same problem when building with maven using RC

From my pom.xml

<dependency>
<groupId>com.sencha.gxt</groupId>
<artifactId>gxt</artifactId>
<version>3.0.0-rc</version>
</dependency>

And here is the problem from maven :

Downloading: http://repo1.maven.org/maven2/com/se...t-3.0.0-rc.pom
[INFO] Unable to find resource 'com.sencha.gxt:gxt:pom:3.0.0-rc' in repository central (http://repo1.maven.org/maven2)


Could you fix this please

thanks

Are you sure you aren't having a proxy issue? From every network I have access to, that link retrieves a file correctly. If you click that link, does your browser load/download the pom file as expected?

We don't control maven central, we can only submit artifacts to them to make it easier for other projects to use them.

If you are still having problems, please post a full log, as well as the pom file that you are using so we can attempt to reproduce this.

[hermann.rangamana]

Absolutely sure.
I tried to get those file using my corporate access network or my home internet access, both fails. And when i try to list the content of the directory http://repo.maven.apache.org/maven2/com/sencha/gxt/gxt/, i cannot see any 3.0.0-rc version. The latest visible version is the beta4 (see attached images below)

[Colin Alworth]

I wonder if they are perhaps having syncing problems with some of their servers - when I load that page, I do see a 3.0.0-rc link, and then http://repo.maven.apache.org/maven2/.../gxt/3.0.0-rc/ contains the gxt jar, plus other meta data. Perhaps try http://207.223.241.90/maven2/com/sencha/gxt/gxt/ which resolves to the IP that I see from their DNS entry - do you see 3.0.0-rc there?

Could you also try from more than one network, to be certain that there isn't a possible proxy or dns issue at your primary location? And is there any chance you are using a VPN from your home internet which could give it the same results as your office?

I'm sorry this isn't working for you, but we don't have any control over apache's servers. We are planning on hosting our own repositories for a final release. In the meantime, try this as a possible workaround - do you see 3.0.0-rc at https://oss.sonatype.org/content/rep...encha/gxt/gxt/ ? If so, try adding https://oss.sonatype.org/content/repositories/releases/ as a repository, so that you might be able to load from the servers we sync with before maven central downloads.

[hermann.rangamana]

Thanks for your prompt reply!
Using the ip address, i can see the 3.0.0-rc version (@http://207.223.241.90/maven2/com/sencha/gxt/gxt/ ), so i guess it's a sync problem on some of their servers. I can also see the rc version at https://oss.sonatype.org/content/rep...encha/gxt/gxt/, so i will add this one as repository for now to get the rc version.

again, thanks for your help

Hermann

[Colin Alworth]

I'm glad this has been resolved for you.

Can you give me the IP that you are getting for repo1.maven.org and repo.maven.apache.org so that I can follow up with either Sonatype or Apache to see why this sync isn't working correctly?

[hermann.rangamana]

Hi Colin,

Both names (repo1.maven.org and repo.maven.apache.org) direct me to 89.167.251.252.
