I use Eclipse Indigo for java development but I want to experiment with scala. Since I have to download a nightly build to run on Eclipse : http://scala-ide.org/download/nightly.html is this safe ?
Is there a chance the plugin can corrupt my eclipse installation since the plugin is not a full blown release as yet ?
I run the latest Scala milestone with no problems right now, which is probably safer than the nightly, and has better highlighting features. If you do run into trouble you can always revert to a previous installation state in Eclipse, so I would consider it safe
The plugins architecture is designed so that Eclipse is protected from instability, unless they maliciously delete files on your installation, I doubt they would break Eclipse permanently. To be extra careful you can make a backup of your eclipse directory.
