Answer 1

You need to add sbteclipse plugin to your plugin definition file (for this, most likely the global one,- in your setup C:\Users\Shweta.sbt\0.13\plugins\plugins.sbt), after that you will be able to use eclipse command.

Make sure to call reload in sbt shell if the file was updated without leaving the shell.

Check out sbteclipse GitHub for more details.

Answer 2

With "current" undocumented as far as I know version 1.2.0 (as of Aug 6th 2018) it would be:

C:\Users\Shweta.sbt\1.0\plugins\plugins.sbt

I tested this on my Windows 10 and eclipse command was successful.

Answer 3

You need the sbteclipse plugin definition in order to execute the eclipse command.

You can add the plugin definition either:

• in the global plugins file at ~/.sbt/<SBT_VERSION>/plugins/plugins.sbt
• or in your local project plugins file at <PROJECT_DIR>/project/plugins.sbt

The plugin has to be added by adding the definition as:

`addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "<PLUGIN_VERSION>")`

For example:

`addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "5.2.4")`

After adding the plugin definition you can run the eclipse command as:

[play-scala-app] $ eclipse
