Scala IDE for Eclipse

This is the new home of the Scala IDE for Eclipse. Previously, source code was hosted on Assembla.

Tickets are still hosted on Assembla, the documentation is available from the website:

• https://www.assembla.com/spaces/scala-ide/tickets
• http://www.scala-ide.org/docs/

Build

The Scala IDE for Eclipse can be built on the command line using Maven, as is done, for example, during the Jenkins-driven nightly builds on jenkins.scala-ide.org. Using a Unix-like OS, the process is as follows ...

• Requirements,

  • The Git command line tools (this will be available as a standard package for Linux distributions)
  • A recent JDK (the current Oracle JDK is recommended)
  • Maven 3

• (Inital setup) Retrieve the source from its git repository, and make sure to checkout the master branch

   # Clone and checkout master branch
   $ git clone git://github.com/scala-ide/scala-ide.git
   $ cd scala-ide

• (Subsequent updates) Update the source from the repository,

   $ cd scala-ide
   $ git pull

• Build

The first time, run ./build-all.sh (or ./build-all.sh install -P scala-2.10.x for 2.10) from the root to generate an initial build and install the top pom locally.

Assuming your build is successful you should find an Eclipse update site has been built in org.scala-ide.sdt.update-site/target/site and a zipped version of the same at org.scala-ide.sdt.update-site/target/site_assembly.zip. You can install directly into Eclipse from this update site by adding it as a local update site via the Eclipse "Install New Software ..." action. Alternatively, if you make the unpacked site available via a web server, then the http URL of its root directory is acceptable as an ordinary Eclipse update site URL.

After that, normal maven calls can be used from any part of the project. Use the scala-2.10.x profile (-P scala-2.10.x) to compile the 2.10 version.

Working with local version of the Scala Presentation Compiler

• Make your local changes in the scala compiler

• Build the scala compiler, package into maven format and deploy locally,

  # You are in the main scala directory
  $ ant distpack-opt
  $ (cd dists/maven/latest; ant -Dlocal.snapshot.repository=${LOCAL_REPO} -Dlocal.release.repository=${LOCAL_REPO} deploy.snapshot.local)
  # If you use the standard .m2 location for maven, then the last command reduces to
  $ (cd dists/maven/latest; ant deploy.snapshot.local)

• Go to directory where you cloned your scala-ide and run the necessary scripts that use your local trunk version

  $ (cd org.scala-ide.build-toolchain; ./build-toolchain-local-trunk.sh)
  $ (cd org.scala-ide.build; ./build-ide-local-trunk.sh)

If the build was successful you will end up with a right update-site - it contains the local changes you made in the scala compiler. It is possible to start the Eclipse instance with that plugin within your original workspace. You just have to have the following projects open org.scala-ide.{sdt.core, scala.compiler, scala.library}. Build sdt.core project within Eclipse and run the configuration using the weaving launcher.
