Details

The Scala IDE for Eclipse is centered around seamless integration with the Eclipse Java tools, providing many of the features Eclipse users have come to expect including,

  • Support for mixed Scala/Java projects and any combination of Scala/Java project dependencies. Type driven operations are transparent across Scala and Java files and projects, allowing straightforward references from Scala to Java and vice versa.
  • A Scala editor with syntax highlighting, inferred type and scaladoc hovers, hyperlinking to definitions, code completion, error and warning markers, indentation, brace matching.
  • Project and source navigation including Scala support in the Package explorer view with embedded outline, outline view, quick outline, open type, open type hierarchy.
  • Incremental compilation, application launching with integrated debugger, hyperlinking from stacktraces to Scala source, interactive console.
  • Support for Eclipse plugin and OSGi development including hyperlinking to Scala source from plugin.xml and manifest files.

The Getting Started Guide is the starting point for the installation guide and other information regarding the use of the Scala IDE for Eclipse.

General discussion, support and troubleshooting questions are welcome on the user mailing list. Your question might already have been answered, so please refer to the user documentation and search the list archives for answers before posting.

The Scala IDE is open source, released under a BSD-like license, written in Scala (with a modest amount of AspectJ-based monkey-patching of the JDT) and community involvement in its development is strongly encouraged. See the developer documentation for information on how to contribute, subscribe to the developer mailing list and follow @ScalaIDE on Twitter.

I am trying to install the Scala IDE plugin to my STS but since yesterday I get this error:

Unable to read repository at https://marketplace.eclipse.org/content/scala-ide.
Unable to read repository at https://marketplace.eclipse.org/content/scala-ide.
https://marketplace.eclipse.org/content/scala-ide is not a valid repository location.

 

It seems that there is a problem with the repository. Please, can you help me? Thanks in advanced!
