Its not yet officially available, but can be downloaded directly from the codebase:
google-web-toolkit.googlecode.com/svn/trunk/ prebuilt folder in here  is the gwt-dev-plugin.xpi, and it works like a charm :)

Previously i wrote when the plugin was updated to work with Firefox 7 and 8.

More info in the group discussion: “GWT Developer Plugin for Firefox 9”

What timing, as Mozilla is likely to release Firefox 10 this coming Tuesday. For the sake of web developers that use GWT, i hope the plugin updates can come sooner in the future.

UPDATE 2012-02-02: This thread in the google group follows plugin development for Firefox 10.

I ended up creating this little handy script based on webkit2png (download source)

#!/usr/bin/env sh
HOST="http://localhost:8080/myproject/viewer"
/usr/bin/python webkit2png -F -o "01dashboard" $HOST/dashboard
/usr/bin/python webkit2png -F -o "02showdetail" $HOST/detail
/usr/bin/python webkit2png -F -o "03listpage" $HOST/list

$ ls -1
01dashboard.png
02showdetail.png
03listpage.png

<!-- settings.xml -->
<mirrors>
  <mirror>

    <mirrorOf>*</mirrorOf>
    <name>Mirror of the world outside.</name>
    <url>http://nexus_url/nexus/content/groups/public/</url>
  </mirror>
</mirrors>

The reason for this being evil was our project pom files which had the following references

<properties>
  <nexus.url>http://nexus_url/nexus</nexus.url>
  <subversion.url>http://svn_url/svn</subversion.url>
</properties>

  <scm>
    <connection>scm:svn:${subversion.url}/common-gwt-gui/trunk</connection>
</scm>

<repositories>
    <repository>
        <id>nexus-repo-releases</id>
        <name>Nexus Repo</name>
        <url>${nexus.url}/content/groups/public/</url>
        <releases> <enabled>true</enabled> </releases>
        <snapshots> <enabled>false</enabled> </snapshots>
    </repository>
    <repository>
        <id>nexus-repo-snapshots</id>
        <name>Nexus Repo</name>
        <url>${nexus.url}/content/groups/public-snapshots/</url>
        <releases> <enabled>false</enabled> </releases>
        <snapshots> <enabled>true</enabled> </snapshots>
    </repository>
 </repositories>

[repeat the <repositories> section for <pluginRepositories>]

<distributionManagement>
    <repository>
        <id>company.releases</id>
        <url>${nexus.url}/content/repositories/company/</url>
    </repository>
    <snapshotRepository>
        <id>company.snapshots</id>
        <url>${nexus.url}/content/repositories/company-snapshots/</url>
    </snapshotRepository>
</distributionManagement>

Finally we have the maven release-plugin, but this irrelevant for now:

<build>
    <plugins>
        <plugin>
            <artifactId>maven-release-plugin</artifactId>
            <configuration>
                <tagBase>${subversion.url}/project_name/releases</tagBase>
            </configuration>
        </plugin>
    </plugins>
 </build>

Error message: Using the wrong repository for snapshots

Now, the generic mirrorOf * in settings.xml actually overrides the specific repository information we set in the pom.xml. Because of that setting, the pom.xml <repository> is not used. And the result is an error message like this. (error message enhanced in bold)

Notice that the errormessage actually gave the ID of our <mirror> from settings.xml:
<!-- settings.xml -->
 <mirrors>
   <mirror>
     <id>insideFirewallRepo</id>

<repositories>
<repository><id>nexus-repo-releases</id><repository>
<repository><id>nexus-repo-snapshots</id><repository>

<!-- settings.xml -->
<mirrors>
  <mirror>
    <id>insideFirewallRepo</id>
    <mirrorOf>!nexus-repo-releases,!nexus-repo-snapshots,*</mirrorOf>
    <name>Mirror of the world outside.</name>
    <url>http://nexus_url/nexus/content/groups/public/</url>
  </mirror>
</mirrors>

Most users could probably just remove the <mirrors> block from settings.xml, but in this particular project, that is not possible since firewall blocks for access to maven central. So, in order for us to use external dependencies, we must use the <mirror> in settings.xml

Then, you could argue, to use <proxy> instead of <mirrors> in settings.xml. This may be a decent solution as well, but in my case i wanted to avoid that, since the company proxy required user/password. Our jenkins build machines would then have my username/password, and it would lock my account whenever my password expires.

Within those constraints, the <mirror> block with excluded internal repositories seems like a decent fit.

For the issues described in this article, I have been using Maven 3.0.3 and Sonatype Nexus 1.9.2

So i ended up with some short search/replace, which are really handy in IntelliJ.

Replace “assertTrue” and “assertFalse” with “assertThat”

Search template

assertTrue($msg$, $actual$);

Replacement template:

org.junit.Assert.assertThat.assertThat($msg$, $actual$, org.hamcrest.core.Is.is(true));

Remove “assertEquals” with delta values

Search template

assertEquals($msg$, $expected$, $actual$, $delta$);

Replacement template:

org.junit.Assert.assertThat($msg$, $actual$, org.hamcrest.core.Is.is($expected$));

Optional Replace “assertEquals” with “assertThat”

Search template

assertEquals($msg$, $expected$, $actual$);

Replacement template:

org.junit.Assert.assertThat.assertThat($msg$, $actual$, org.hamcrest.core.Is.is($expected$));

Since Firefox 7 was released, i have defered upgrading for one simple reason: At work I am dependent on GWT Developer plugin.

Today I found the ready-to-release plugin which actually works with Firefox 7:

http://google-web-toolkit.googlecode.com/svn/trunk/plugins/xpcom/prebuilt/ in here  is the gwt-dev-plugin.xpi, and it works like a charm :)

(In firefox, it asks you to download. And then you can drag the downloaded .xpi back into the browser to install. Why Firefox will not instantly recognize the .xpi file is kind of strange)

These are typically from situations where I found a useful way, which I wanted to jot down. Also I have answered and asked some questions on StackOverflow. The good thing about it, is that I am always able to find it again this way.

IN this spirit, i created a quick @WTF annotation for Java.

Besides being completely useless (its removed at compile time), its only purpose is to give developers a new way to express themselves in code.

The cartoon states “The only valid measurement of code quality: WTFs/minute”. With the <code>@WTF</code> annotations, I would like to take it a little further. By annotating the code, you can actually encourage colleagues to help you fix it.

The best fix for WTF-code is of course to refactor, so that it becomes readable.

Delete all files in temp folder:

I wanted to set up the pre-commit hook so that commits with empty comment are automatically rejected.

All commit-hook example files that go with Subversion are written in bash (as unix servers tend to be the normal).

Here is a the pre-commit hook rewritten as a windows .bat file.

I decided to import the data into a local database to ensure it could work offline.

Code from

file:

Now I can access municipalities in a grouped selectbox like so in the view code:

<%
 options = option_groups_from_collection_for_select(Region.all, :kommuner, :name, :id, :name)
%>

<%=
 f.select("kommune_id", options, {}, {:class => "short"})
%>

The final result rendered in the user interface:

This code is based on Rails 2.3.5.
