So feel free to… copy and paste!

I’m using Eclipse 3.5 with the IvyDE plugin. With those installed I created a new Java Project and then set about creating my ivy.xml. My projects pretty much all have the same basic dependencies

  • Spring (3.0.3.RELEASE since that’s the latest)
  • Hibernate (3.5.3.Final)
  • Hibernate-search (Makes indexing my model nice and easy)
  • Jodatime (Awesome for date manipulation)
  • Jodatime-hibernate
  • H2 database (I always start of with a mock in-memory at start of dev and then use some JPA magic to dump out a schema to DB2 or Sybase, or whatever else DB is in use)
  • SLF4J (My logging api of choice)
  • Jackson (For any restful services I might write)

Here’s my ivy.xml

I’m going to get my spring dependencies from Springsource’s ivy/maven repository, but everything else will come from a mix of JBoss and Maven2 repo’s. Here’s the ivy-settings.xml 

< ?xml version="1.0" encoding="ISO-8859-1"?>
<ivysettings>

	<caches artifactPattern="[organisation]/[module]/[revision]/[artifact].[ext]" />
	<settings defaultResolver="ibiblio.jboss.java-net.springsource" checkUpToDate="true" />

	<resolvers>

			</url>
		</chain>

	</resolvers>
</ivysettings>

After plugging the above into Eclipse and setting up my IvyDE classpath container to use the new ivy-settings.xml file there was one more thing to do which was to tell IvyDE what type the source jars were. Go to “Window” -> “Preferences”, find “Ivy” -> “Classpath” in the tree and on that page under the option for “Source types” enter “source,src,srcs”. Save and you should get source code attachment to the jars too. Note that you can tell your Eclipse project to use the ivy-settings within it by going right clicking on your Ivy classpath container and under “Ivy Settings Path” enter project:///ivy-settings.xml

So after following all the steps I decided to keep my existing tomcat6 script under /etc/init.d/tomcat6 because I’d customised it for launching Subsonic Music Server. However after restarting my machine after upgrading I noticed subsonic was not running. So I dug a bit deeper and found that I was missing the jsvc package. Running:

sudo apt-get install jsvc

got me sorted and Subsonic is back alive!

In the office we have our repository to store all the libraries we have in our environment and so the setting up of resolvers etc is all taken care off. Out in the real world you need to do this yourself, but the beauty of Ivy is its simple. First up I’m using Eclipse 3.4 with the IvyDE plugin. With those installed I created a new Java Project and then set about creating my ivy.xml. For this project there are a few requirements I wanted.

  1. I want to use Spring for config
  2. I want to have a play with Compass – the lucene abstraction

Out of the box Ivy will use the “ibiblio” resolver which makes use of the Ibiblio’s Maven repository. This is not really the greatest starting point as its not so easy to find stuff in. Spring however have their own repository with a lot of open source libraries and is much easier to search http://www.springsource.com/repository/app/. So my ivy.xml file looks like:

< ?xml version="1.0" encoding="ISO-8859-1"?>
<ivy -module version="2.0">

	<info organisation="matt" module="compassTest" status="integration" />

	<dependencies>
		<dependency org="org.springframework" name="org.springframework.context.support"
			rev="2.5.6.A" />
		<dependency org="org.compass-project" name="compass" rev="2.2.0-M2" />
	</dependencies>

</ivy>

Very simply I want to use Springs context support classes and I want to have play with Compass. In order to get this all to work I needed to create my own ivy-settings.xml with some new resolvers. First I need to add Springs repository resolvers (Doc’d here), then I need to add Compass’s Maven repo and finally Compass depends on a version of Lucene not in Springs repository so I need to add in ibiblio’s Maven2 repository. My final ivy-settings.xml file looks like:

< ?xml version="1.0" encoding="ISO-8859-1"?>
<ivysettings>
	<settings defaultResolver="spring.compass.ibiblio" checkUpToDate="true" />
	<resolvers>
		<chain name="spring.compass.ibiblio">
			<url name="com.springsource.repository.bundles.release">
				<ivy pattern="http://repository.springsource.com/ivy/bundles/release/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" />
				<artifact pattern="http://repository.springsource.com/ivy/bundles/release/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" />
			</url>
			<url name="com.springsource.repository.bundles.external">
				<ivy pattern="http://repository.springsource.com/ivy/bundles/external/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" />
				<artifact pattern="http://repository.springsource.com/ivy/bundles/external/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" />
			</url>
			<ibiblio name="compass" m2compatible="true" root="http://repo.compass-project.org" />
			<ibiblio name="ibiblio" m2compatible="true" />
		</chain>

	</resolvers>
</ivysettings>

After plugging the above into Eclipse and setting up my IvyDE classpath container to use the new ivy-settings.xml file all was good. Simples!
