How to use sbt-eclipse to create Eclipse project files of a project?

Question

I followed the official documentation to set up the plugin in my sbt project: - Added `addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.5.0")` to `~/.sbt/plugins/plugins.sbt` file - `cd`ed to a project and ran `sbt` - In sbt shell, typed `eclipse` That's where I faced the following error: ``` > eclipse [error] Not a valid command: eclipse (similar: help, alias) [error] Not a valid project ID: eclipse (similar: sbteclipse) [error] Expected ':' (if selecting a configuration) [error] Not a valid key: eclipse (similar: deliver, licenses, clean) [error] eclipse [error] ^ ``` What am I missing? Thanks in advance for any help you can give me. ``` $ /opt/sbt-0.13.5/bin/sbt [warn] The global sbt directory is now versioned and is located at /Users/first.last/.sbt/0.13.

I'm using sbt 0.13.5.

```
$ sbt --version
sbt launcher version 0.13.5
```

In an empty directory executed `sbt about` to check the build/sbt setup.

```
$ sbt about
[info] Loading global plugins from /Users/jacek/.sbt/0.13/plugins
[info] Updating {file:/Users/jacek/.sbt/0.13/plugins/}global-plugins...
[info] Resolving org.fusesource.jansi#jansi;1.4 ...
[info] Done updating.
[info] Set current project to sbteclipse (in build file:/Users/jacek/sandbox/sbteclipse/)
[info] This is sbt 0.13.5
[info] The current project is {file:/Users/jacek/sandbox/sbteclipse/}sbteclipse 0.1-SNAPSHOT
[info] The current project is built against Scala 2.10.4
[info] Available Plugins: sbt.plugins.IvyPlugin, sbt.plugins.JvmPlugin, sbt.plugins.CorePlugin, sbt.plugins.JUnitXmlReportPlugin, net.virtualvoid.sbt.graph.Plugin, com.timushev.sbt.updates.UpdatesPlugin
[info] sbt, sbt plugins, and build definitions are using Scala 2.10.4
```

No files are in the directory (disregard `target` since it's automatically created by sbt upon startup and can be removed at any time).

```
$ tree
.
`-- target

1 directory, 0 files
```

I then ran the sbt shell with `sbt` to ensure no `eclipse` command existed.

```
$ sbt
[info] Loading global plugins from /Users/jacek/.sbt/0.13/plugins
[info] Set current project to sbteclipse (in build file:/Users/jacek/sandbox/sbteclipse/)
> eclipse
[error] Not a valid command: eclipse (similar: help, alias)
[error] Not a valid project ID: eclipse (similar: sbteclipse)
[error] Expected ':' (if selecting a configuration)
[error] Not a valid key: eclipse (similar: deliver, licenses, clean)
[error] eclipse
[error]        ^
```

I could reproduce your issue. Moving on to setting up the plugin - I did not close the sbt shell.

Following the documentation closely I opened `~/.sbt/0.13/plugins/plugins.sbt` to have it as follows:

```
$ cat ~/.sbt/0.13/plugins/plugins.sbt
addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.5.0")
```

With the plugin in the file, I fired `reload` in the sbt shell to load the changes.

```
> reload

```

As you can see the plugin was properly loaded and generated the files. Follow the steps and you should have the plugin installed with no issues.
