Eclipse Scala IDE 2.0.0 (RC3) for Scala 2.9 and 2.8 is out

I attempted to install RC3 and installation failed.

On a fresh machine I downloaded Eclipse 3.7.1 (Indigo) I used the “Java Developer’s” edition. This is a fresh install of Eclipse.

With no other changes or plugins, I then went to the ScalaIDE site and clicked on the button that says “Copy update site URL to clipboard.” I attempted to install ScalaIDE for Eclipse and received the following error:

“Software currently installed: Shared profile 1.0.0.1316138547364 (SharedProfile_epp.package.java 1.0.0.1316138547364)

  Missing requirement: Shared profile 1.0.0.1316138547364 (SharedProfile_epp.package.java 1.0.0.1316138547364) requires 'org.maven.ide.eclipse [1.0.100.20110804-1717]' but it could not be found”

Does this mean the Scala plugin can’t be installed on a stock download of Eclipse? Is that the intent? Is that documented somewhere? I do see on the ScalaIDE page that Eclipse Classic is required. I assumed the Java Developer edition was a superset of the classic distribution. Perhaps not.

A new Release Candidate (RC3) for the coming 2.0.0 final release of the Eclipse IDE for Scala is ready for download! This release candidate includes an important update that makes the Scala IDE compatible with the latest released Spring IDE plugin, and one additional fix for correctly handling incremental compilation of mixed Java/Scala projects. We will wait at least one week before issuing a final release, in order to allow developers and testers to send us their feedback.

A colleague recently had the same error when trying to install
plug-ins (not the Scala IDE, in his case it was EGit and PyDev). Are
you on Windows 7 too? For him, the solution was to run Eclipse as
Administrator:

Yes, that helped. I actually just reinstalled Eclipse to a location where I have full R/W access and it seems to work fine.

Is it me or does this make Eclipse look rather broken? Windows has been a multi-user system for a while now and Eclipse is supposedly a professional quality tool. Why can't it handle the multi-user environment? At the least it would be nice if produced a more intelligible error message.

I realize this problem isn't due to the Scala plug-in but it might be nice to have something about it on the Scala IDE home page. Otherwise I could easily see someone who wants to experiment with Scala and who encounters this error just writing off Scala as "not yet ready for prime time" without any further investigation.

Hi Peter,

I installed Eclipse + Scala IDE a few months ago on Windows 7 and I had no
issues at all.

Nevertheless, I agree it can be useful to have a note on the Scala IDE FAQ.

Cheers,
Mirco

Yes. I originally opened an administrative command prompt and extracted the Eclipse distribution to “C:\Program Files.” Since I was putting the application in a “public” place it seemed logical to me that I should do it as administrator. To fix my issue I deleted my previous installation and extracted the Eclipse distribution, as myself, to a different folder where I have full R/W access.

In contrast IntelliJ works more, well, intelligently. It installs to “C:\ Program Files (x86)” with limited access to ordinary users. However, all the plugins (that I’ve tried anyway) just modify files in my profile and thus install fine. IntelliJ does sometimes offer to upgrade itself and when I tried that as an ordinary user it failed. However it did produce a useful error message about having insufficient permission.

NetBeans is the most intelligent of all. It also installs to “C:\Program Files” with limited access to ordinary users. All the plugins I’ve tried with it install fine into my profile. When it tried to upgrade itself, even that worked fine. I was a bit surprised by that but apparently it just installs all the new jars into my profile as well. Thus when I launch NetBeans it starts loading from the original installation but then in some way merges in the upgraded material seamlessly. I find that a bit scary but it appears to work.

I don’t like Eclipse much. I realize this isn’t the place to go on about that, but I’ll just say that this is yet another example of why I think Eclipse is the most inferior of the “big three” IDEs.

As far as I can see, Eclipse is always provided as a zip download. At least that seems to be the situation here

                http://www.eclipse.org/downloads/

Presumably the others provide a native installer. When a program is provided as a zip download, it probably doesn't assume that you're putting it in a restricted location.
