It has been a while since my initial posts on using Maven with Spring Android, and the state of the tools has changed somewhat. With the recent release of the SDK for Android 4.0 and revision 14 of the Android Development Tools (ADT), Google made several changes that impacted the third party Maven plugin support for building Android projects. Fortunately, the teams behind the Android Maven Plugin, and the Android Configurator for M2E have been hard at work to support these latest changes in the Android tools. If you have tried to run the Spring Android Samples recently, then you probably noticed the projects would not build. In this post, I will illustrate the configuration changes necessary to utilize the latest Maven plugins and Eclipse support in the Spring Android Showcase project.

Android Maven Plugin

As of version 3.0.0-alpha-11, The Maven Android Plugin now has a new name, and is now called the Android Maven Plugin. The latest version, 3.0.0-alpha-13 fixes the build issue with Android SDK r14.

Update the Plugin

To update your plugin version, make the following changes to the artifactId and version.

<plugin>
    <groupId>com.jayway.maven.plugins.android.generation2</groupId>
    <artifactId>android-maven-plugin</artifactId>
    <version>3.0.0-alpha-13</version>
    <configuration>
        <sdk>
            <platform>${android-platform}</platform>
        </sdk>
        <deleteConflictingFiles>true</deleteConflictingFiles>
        <undeployBeforeDeploy>true</undeployBeforeDeploy>
    </configuration>
    <extensions>true</extensions>
</plugin>

Once modified, you can now run maven from the command line to build your project.

mvn clean install

Potential Build Errors

It is possible that your project will receive a few build errors when you try to build with the new plugin.

java.lang.OutOfMemoryError

When I updated the Spring Android Showcase client, the build failed with the following:

[INFO] UNEXPECTED TOP-LEVEL ERROR:
[INFO] java.lang.OutOfMemoryError: Java heap space

If you watched the video for the Cloud Foundry launch event, you saw that we deployed the Spring Travel application downloaded from Spring Web Flow samples, bound a MySQL service to it, and dragged and dropped the application to the Cloud Foundry server in STS, without making a single line of change in the application itself. How’s that possible since the application is configured to use a local database? That’s when auto-reconfiguration comes into play.

Cloud Foundry strives to keep your initial investment low. Beyond dollars and cents, a real investment comes from the time that a developer…

Wow! Last week's SpringOne 2GX event was sensational. It was an amazing time, and it was - as usual - great to see the Spring community going so strong. I can't wait until the videos from the event start to appear on InfoQ.com.

We've got a lot to cover this week, though, so let's get into it!

Don't tell anyone, but even if you missed SpringOne 2GX, the decks for all the talks should be on SpringOne2GX.com, and the videos for all the talks will be on InfoQ.com soon.

To tide you over in the short term, the deck from SpringSource CTO Adrian Colyer's keynote - "Spring yesterday, today, and tomorrow" - is available online. Thanks Adrian!

 One of the many big announcements that came from the SpringOne2GX event was	 that of <a href= "http://neo4j.org/spring/">Neo4j 2.0</a>.

Dear Spring Community,

I am happy to announce the new milestone release M5 of the Cloud Foundry Integration for the SpringSource Tool Suite (STS).

This milestone release includes support for debugging applications in Cloud Foundry (for local clouds and the upcoming version of Micro Cloud Foundry). You can now start your apps in your local or micro cloud in debug mode and your Eclipse/STS debugger will automatically be connected to your app running inside of Cloud Foundry. You can set breakpoints, inspect variables, evaluate expressions, step through the app - everything you know from he good…

Dear Spring Community,

I am pleased to announce that the Spring Data MongoDB 1.0 Milestone 5 release is now available!

The primary goal of the Spring Data project is to make it easier to build Spring-powered applications that use new data access technologies such as non-relational databases, map-reduce frameworks, and cloud based data services.

The MongoDB module provides integration with the MongoDB document database.

There are a number of bug fixes and minor changes to the way certain features work. See the changelog…

Dear Spring Community,

We are pleased to announce that the first milestone release (2.0.0.M1) of the new Spring Data Neo4j major version 2.0 is now available!

In the last few weeks the engineers have been busy transforming the existing library under a new name to make it fit for its presentation
at Spring One 2GX next week.

A major internal refactoring split the framework into several submodules, each addressing a different concern.

• spring-data-neo4j: Neo4jTemplate for easy, copying object-graph-mapping, and Spring Data Repositories using persistence entity meta information
• spring-data-neo4j-aspects: transparent object-graph-mapping using AspectJ
• spring-data-neo4j-cross-store: AspectJ based cross-store-persistence between JPA and Neo4j
• spring-data-neo4j-rest: transparent access of a remote Neo4j REST-Server

As part of the refactoring, the source repository was also renamed and re-organized. The previously separated examples and the tutorial project are now included directly in the same github project…

What a week! If you're an enterprise Java developer, then you've no doubt heard the news - Spring 3.1 RC1 has just been released! Read on for more details and be sure to sound off on the forums if you have questions or feedback!

And, of course, if you're at SpringOne2GX 2011 next week, you can look forward to hearing a lot more on Spring 3.1 as well as the latest and greatest from all the Spring technologies. We look forward to seeing you all there!

 </P>
