Nicolas Lalevée resolved IVYDE-272.
-----------------------------------
Resolution: Fixed
Fix Version/s: trunk
Assignee: Nicolas Lalevée
Now the retrieve will fail is the resolved pattern is the root of the project.
> IvyDE deletes entire project!
> -----------------------------

> Key: IVYDE-272
> URL: https://issues.apache.org/jira/browse/IVYDE-272
> Project: IvyDE
> Issue Type: Bug
> Components: workspace resolver
> Affects Versions: 2.1.0
> Environment: Eclipse Version:
> 3.6.1.r361_v20100909-9gF78GrkFqw7GrsZnvz0JWNTeb6fue6896L Build id:
> M20100909-0800
> IvyDE Version 2.1.0.201008101807
> Running on MacBook Pro running Mac OS X Leopard 10.6.5
> Reporter: Kevin G
> Assignee: Nicolas Lalevée
> Priority: Critical
> Fix For: trunk
>
>
> With the "Delete old retrieve artifacts" option active, the IvyDE extension
> deleted my entire project directory! The only thing in my workspace project
> folder is a list of jars (resolved from my ivy file, which was deleted)!!!
> After looking into this further, I think this most likely happened because my
> retrieve pattern did not contain /lib. It was just:
> [artifact]-[revision].[ext] (I may have had an ivy property on the front as
> in ${project.lib}/[artifact]-[revision].[ext])
> Still, this should never happen!
> Luckily, I had everything checked into version control but this could have
> been a disaster.
> -----------------------------------------------------
> Steps I took:
> I installed IvyDE about 15 minutes ago, via Eclipse Marketplace. After
> eclipse restart I right clicked on the project and chose Build Path > Add
> Libraries > IvyDE Managed Dependencies.
> On the main tab, I chose my ivy file from the workspace.
> On the settings tab, I enabled project specific settings and chose my
> settings file and properties file from the workspace.
> On the retrieve tab, I enabled project specific settings, chose "do retrieve
> after resolve" and set my retrieve pattern to the exact value of my
> ivy.retrieve.pattern variable which was [artifact]-[revsion].[ext] (I may
> have had a property on the front like ${project.lib} which is in my ivy
> properties file)
> On the advanced tab, I enabled project specific settings and set "order of
> the classpath entries" to lexical
> I clicked FINISHED and it deleted my entire project!!!!!
> Leaving only the jars in it's place.
> ###
> The person fixing this should verify that this does not happen when the
> retrieve pattern contains an unknown variable such as:
> ${some.variable}/[artifact]-[revision].[ext]
> ###
> Also, if the artifact variable is going to result in the entire project being
> deleted, at least a warning should be displayed. Perhaps red text at the
> bottom that displays:
> Warning: all files in the directory
> /full/path/to/directory/derived/from/retrieve/pattern will be deleted.
> (where the full path to the retrieve location is derived based on the
> retrieve pattern)
> Lastly, I would recommend changing the default pattern for types from * to
> *.jar
> That one change, alone, would have prevented this from happening.
