Using Spring BlazeDS Integration nightly builds with Maven

[jeremyg484]

For those of you who are using Maven for your project builds and depending on maven-central-compatible pom's (i.e., not the OSGi-ready dependencies in the SpringSource Enterprise Bundle Repository), I thought it would be worth documenting the process of pulling a nightly snapshot build of Spring BlazeDS Integration into your project in case you don't mind living on the edge a little (i.e., fair warning that things might break) and are in need of the latest fixes in between releases.

All development is now happening in SVN trunk for what will eventually be version 1.5.0. At this point we have no intention of any further 1.0.x releases unless a critical bug arises.

Currently, the only snapshots we are publishing are the core Maven artifacts for 1.5.0. We have not yet incorporated publishing of a full .zip distribution with docs, source, etc. (as we did with 1.0.x) into our nightly build process. We will likely begin publishing a full nightly distro right before we release the first 1.5.0 Milestone.

As a consequence of our migration to Maven as the single build system for the project, as well as the fact that there will eventually be additional artifacts included (beyond just the core jar) in 1.5.0, the main dependency's artifact id has changed to spring-flex-core.

To grab the current nightly snapshots with Maven, you must first have the maven.springframework.org snapshot repository configured either in your settings.xml (preferred) or directly in your project's pom. The correct format of the repository entry is:

<repository>
    <id>spring-snapshot</id>
    <name>Spring Portfolio Snapshot Repository</name>
    <url>http://maven.springframework.org/snapshot</url>
    <releases>
        <enabled>false</enabled>
    </releases>
    <snapshots>
        <enabled>true</enabled>
    </snapshots>
</repository>

Once you have the correct repository settings, you would express a dependency on spring-flex-core as follows:

<dependency>
    <groupId>org.springframework.flex</groupId>
    <artifactId>spring-flex-core</artifactId>
    <version>1.5.0.BUILD-SNAPSHOT</version>
</dependency>

*** One problem you will likely encounter is that 1.5.0 depends on BlazeDS 4, which is not currently published in any known public Maven repository. You will need to install the BlazeDS 4 Maven artifacts into your local repository in order to build successfully against the 1.5.0 nightly snapshots. For example, you can use 'mvn install:install-file' to install to your local repository, or 'mvn deploy:deploy-file' to install to your own hosted repo. You can grab the necessary pom's from our SVN repository here:

https://src.springframework.org/svn/...ds-4.0.0.14931

I am trying to build testdrive with Maven. At first I thought this applied to testdrive but now I think it applies to the lib.

That said, I am getting an error when I try to build testdrive from the nightly build with maven. After I run mvn install I get the following error in the cmd window.



[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Failed to resolve artifact.

Missing:
----------
1) org.springframework.flex:spring-flex:jar:1.0.1.BUILD-SNAPSHOT

Try downloading the file manually from the project website.

Then, install it using the command:
mvn install:install-file -DgroupId=org.springframework.flex -DartifactId=s
pring-flex -Dversion=1.0.1.BUILD-SNAPSHOT -Dpackaging=jar -Dfile=/path/to/file

Alternatively, if you host your own repository you can deploy the file there:

mvn deploy:deploy-file -DgroupId=org.springframework.flex -DartifactId=spr
ing-flex -Dversion=1.0.1.BUILD-SNAPSHOT -Dpackaging=jar -Dfile=/path/to/file -Du
rl=[url] -DrepositoryId=[id]

Path to dependency:
1) org.springframework.flex.samples:testdrive:war:1.0 .1.BUILD-SNAPSHOT
2) org.springframework.flex:spring-flex:jar:1.0.1.BUILD-SNAPSHOT

----------
1 required artifact is missing.

for artifact:
org.springframework.flex.samples:testdrive:war:1.0 .1.BUILD-SNAPSHOT

from the specified remote repositories:
ObjectWEB (http://maven.ow2.org/maven2/),
central (http://repo1.maven.org/maven2),
flex-mojos-repository (http://repository.sonatype.org/content/groups/public)


Any help would be great. Thanks.

I tried to follow your instructions for building the sbi lib with Maven and I get the following error. Any ideas?

OK, so I figured out what I did wrong. My apologies as I am new to both Spring and Maven.

In order to build the SBI jar I had to be in the folder that had "dist" in it. For my example that was "spring-flex-1.0.1.CI-283-with-dependencies\spring-flex-1.0.1.CI-283". Then I was able to run #2 above with version changes.

To build the Testdrive projects, I added the dependency listed above to the testdrive pom.xml and then I went to "projects\spring-flex-samples\spring-flex-testdrive" and it built too.

Thanks for your work on this guys.

Updated the top post with potentially simpler way to grab the nightly snapshots with Maven.

My maven build is missing the BlazeDS-core jar that the nightly build depends on:
com.adobe.blazeds:blazeds-core:jar:4.0.0.10153


Using this dependency:

		<dependency>
			<groupId>org.springframework.flex</groupId>
			<artifactId>spring-flex</artifactId>
			<version>1.5.0.BUILD-SNAPSHOT</version>
		</dependency>

The blazeds builds posted below do not contain the jar:
http://opensource.adobe.com/wiki/dis...+blazeds+trunk

Where can I get it?

Thank you
