Version dependency problem in eclipse-mylyn
Last modified: 2009-08-18 05:28:46 EDT
Description of problem:
Attempting to install the beta version of the Scala plugin from scala-lang.org,
which depends on Mylyn, triggers the following error:
Mylyn Bridge: PDE, CVS and Ant (2.3.2.v20080402-2100) requires plug-in
"org.eclipse.mylyn.tasks.core (2.3.0)", or compatible
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. yum install eclipse-mylyn\*
2. install Scala plugin: http://www.scala-lang.org/downloads/scala-plugin-beta/
Error message described
The summaries for -ide, -java and -pde could perhaps be made more descriptive.

AFAICT all of the Mylyn plugins have this in META-INF/MANIFEST.MF:
meaning they should accept 2.3.2. Is there perhaps a deeper error here? The
update manager in Eclipse <= 3.3.x doesn't properly expose plugins that are in
/usr/lib (these are arch-specific plugins called "fragments"). This upstream
bug has not been fixed and sometimes 3rd party plugins like this Scala plugin
depend upon something that is arch-specific.
Have you thought about packaging this for Fedora? It's not hard and I wouldn't
mind helping you out.
(Sorry for the late reply, was watching the status which is still NEW)
I've thought of packaging -- will Fedora 10 have Eclipse 3.4? In that case I
might just package the next version of the plugin, which requires that.
The Scala plugin bundles its own copy of Scala; is that the norm for
Eclipse-related packages or would I have to patch it to use a standalone
Yes, Fedora 10 will have Eclipse 3.4.
The Fedora guidelines specify that there should only be one copy of things on
the system so you'd have to patch it to use the system Scala.
Can this bug be considered resolved?
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.
