Java Bien!

The day maven ruined my day (again…)

Yesterday, I lost 2 hours because our Maven project at Algodeal wouldn’t build anymore. I couldn’t execute:

mvn eclipse:eclipse

nor run the full build.

With the help of a colleague, we found out that only a two steps build would do the trick:

mvn clean install -DskipTests;mvn eclipse:eclipse

Obviously maven is already not my best friend but yesterday I was just fed up.

There is a crisis going on within the Maven community. Some think that Maven has become something too complicated, too difficult to maintain and evolve. I say it loud (even if few people care): I fully support these detractors. Read more…

Gwt 1.4.59-RC2 was just released. If you use Maven2 to build your project, this latest version can be found on xi8ix repository.

Here is the configuration:

<repositories>
    <repository>
        <id>xi8ix</id>
        <url>http://maven.xi8ix.org/</url>
    </repository>
</repositories>
<dependency>
    <groupId>com.google</groupId>
    <artifactId>gwt-user</artifactId>
    <version>1.4.59-RC2</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>com.google</groupId>
    <artifactId>gwt-servlet</artifactId>
    <version>1.4.59-RC2</version>
</dependency>

I had to tweak a few things in my SpringDispatchService. Maybe it’s time to find a more stable solution…

Trying to use Maven2 to build a GWT project, here is the simplest pom.xml I came up with, starting from Xavier’s

The project can be tested in debug mode with mvn gwt:gwt. It is tested in deployed mode with mvn jetty:run-war

Don’t forget to provide the gwt-user.jar in src/main/webapp/WEB-INF/lib.

Code legend:
Blue parts depend on your project and installation path.
Red part is only needed on a Mac.
Green part makes it easier to use the Jetty plugin.
