A new version of Clojuresque is released! Changes to v1.1.0:

• warnOnReflection now configurable
• aotCompile now configurable and off by default, see discussion on the google group
• easy integration of Clojars and Hudson repositories
• easy deployment to Clojars

Caveats

Please be sure to read and understand these issues:

• Sitting between the chairs of Clojure's namespace based and the other languages file based compilation, you have to include or exclude namespaces based on filenames for now.

• Automatic recognition of namespaces only works if the ns form is the first in the file. Comments may precede the form. The symbol is allowed to be fully qualified: clojure.core/ns.

• In order for the scp deployment of Clojars to work, you have to replace the jsch jar in ${GRADLE_HOME}/lib with jsch-0.1.29.jar. Otherwise the transfer might hang. See this ant bug for more information.

Clojars Deployment

Additional to configuration of the Upload tasks with configureClojarsDeploy you also have to specify the location of the keyfile and the passphrase you use to access Clojars. This can be done independent of the projects in a file called ${HOME}/.gradle/gradle.properties.

clojarsKeyfile = /Users/mb/.ssh/id_dsa
clojarsPassphrase = My super secret passphrase

Be sure to correctly secure this file! Or your key might be compromised!

Example

Here a non-trivial with AOT compilation, reflection warning and Clojars deployment:

buildscript {
    repositories {
        mavenRepo name: 'clojars', urls: 'http://clojars.org/repo'
    }
    dependencies {
        classpath 'clojuresque:clojuresque:1.2.0'
    }
}

group = 'example.group'
version = '1.0.0'

usePlugin(cojuresque.ClojurePlugin)

warnOnReflection = true
aotCompile = true

clojureSnapshotsRepo(repositories)
clojarsRepo(repositories)
gradleHomeRepo(repositories)

dependencies {
    compile 'org.clojure:clojure:1.1.0-master-SNAPSHOT'
}

configureClojarsDeploy(uploadArchives)

A small walkthrough:

• The buildscript part defines a dependency and automatically fetches clojuresque from Clojars.
• The group and version properties define the respective attributes of your project. They are required for the POM generation. Note that gradle derives the project name from the name of this directory!
• usePlugin basically loads the clojure plugin.
• warnOnReflection turns on the reflection warnings of the clojure compiler
• aotCompile specifies whether to produce a source jar or an AOT compiled jar. The default is produce a source jar, because they also tend to be smaller. This issue was discussed on the Google group.
• clojureSnapshotsRepo tells gradle where to find the clojure and contrib snapshots, ie. where it can find the Hudson server.
• clojarsRepo adds the Clojars Repository in a similar way.
• gradleHomeRepo is used to add ${GRADLE_HOME}/lib as a local repository. This is useful to minimise the download of the scp ant task dependencies. Note that GRADLE_HOME must be set for this to work! Note, that this must come before a possible mavenCentral()!
• In the dependencies section we add a dependency on the current master SNAPSHOT.
• Last but not least: configureClojarsDeploy configures the given Upload task to deploy to the Clojars Repository

This can be even more simplified by registering clojuresque with your local Gradle installation. Put the clojuresque jar in ${GRADLE_HOME}/lib and add the following line to ${GRADLE_HOME}/plugin.properties:

clojure=clojuresque.ClojurePlugin

From now on you can skip the whole buildscript stuff and just use usePlugin('clojure') to load the plugin.
