Publish

This page describes how to publish your project. Publishing consists of uploading a descriptor, such as an Ivy file or Maven POM, and artifacts, such as a jar or war, to a repository so that other projects can specify your project as a dependency.

The publish-local action is used to publish your project to a local Ivy repository. By default, this local repository is in ${user.home}/.ivy2/local. You can then use this project from other projects on the same machine.

The publish action is used to publish your project to a remote repository. To use publishing, you need to specify the repository to publish to and the credentials to use. To specify the repository, assign a repository to val publishTo and define the publishing style. For example, to upload to Nexus:

  override def managedStyle = ManagedStyle.Maven
  val publishTo = "Scala Tools Nexus" at "http://nexus.scala-tools.org/content/repositories/releases/"

There are two ways to specify credentials for such a repository. The first is to specify them inline:

  Credentials.add("Sonatype Nexus Repository Manager", "nexus.scala-tools.org", "admin", "admin123")

The second and better way is to load them from a file, for example:

  Credentials(Path.userHome / ".ivy2" / ".credentials", log)

The credentials file is a properties file with keys realm, host, user, and password. For example:

realm=Sonatype Nexus Repository Manager
host=nexus.scala-tools.org
user=admin
password=admin123

Once this is set up, you can run publish. Even better, enable cross-building and do +publish. See Resolvers for other supported repositories.

By default, the artifact to publish is a war for DefaultWebProject and a jar for DefaultProject. You can declare other types of artifacts to publish by defining Artifact instances. See the Artifacts page for details.

To publish sources and javadocs, add artifact declarations and make the publish-local and publish actions depend on package-src and package-docs:

  override def packageDocsJar = defaultJarPath("-javadoc.jar")
  override def packageSrcJar= defaultJarPath("-sources.jar")
  val sourceArtifact = Artifact.sources(artifactID)
  val docsArtifact = Artifact.javadoc(artifactID)
  override def packageToPublishActions = super.packageToPublishActions ++ Seq(packageDocs, packageSrc)

When managedStyle is ManagedStyle.Maven, a POM is generated by the make-pom action. Override the 'pomExtra' method to provide XML (scala.xml.NodeSeq) to insert directly into the generated pom. For example:

override def pomExtra =
<licenses>
  <license>
    <name>Apache 2</name>
    <url>http://www.apache.org/licenses/LICENSE-2.0.txt</url>
    <distribution>repo</distribution>
  </license>
</licenses>

As of sbt 0.7.0, make-pom adds to the POM any Maven-style repositories you have declared. You can filter these by overriding pomRepositoryFilter, which by default excludes local repositories. For example, to only include local repositories:

override def pomIncludeRepository(repo: MavenRepository) =
  repo.root.startsWith("file:")

There is also a pomPostProcess method that can be used to manipulate the final XML before it is written. It's signature is:

def pomPostProcess(pom: Node): Node
