Buckminster builds don't include linked resources [message #632132]

I'm working on a large scale RCP project at the minute for one of my customers. They want me to improve the build process from using lots of custom Ant and Ivy scripts to something more intelligible. I've decided that Buckminster is the right tool for this job, and have created an appropriate R-Map to map out the project's resources, some C-Queries, etc. These all seem to work pretty well.

The customer uses the ClearCase version control system, however. It's extremely slow to build from because the "bin/" folder in your project lives on a network drive with your other project resources. To work around this, they have set up an Eclipse linked resource that maps "eclipse_build_loc" to, say "D:\Temp\build" for build output. Then inside each plug-in you include the following in the ".project" file.

	<linkedResources>
		<link>
			<name>bin</name>
			<type>2</type>
			<locationURI>eclipse_build_loc/myprojectname</locationURI>
		</link>
	</linkedResources>

This maps the output "bin/" directory to live on your local disk instead of on the network.

Unfortunately when you do a Buckminster build of these plug-ins they don't include the compiled classes. I thought I was so close after mapping out all the dozens of search locations out! Crying or Very Sad

Any suggestions on how to work around this? I've tried debugging the Buckminster process, but the codebase is too large for me to quickly find out what's going wrong. I'm not above patching my version of Buckminster, if necessary, until you guys can come up with a fix for this.

Sadly we can't just take out the linked resources stuff. Are things like a CSPEX to manually force the inclusion of the output directory sane?

A test plug-in that demonstrates this failure is downloadable from here.

I've added a bug for this but that may be premature. I'm having the same problem.

I've posted a patch that goes some way to solving this problem on the bug report.

if you use clearcase, and build over an dynamic view (over the network) i suggest you instead create an snapshot view (local to the machine) and build from that instead.

If only the ClearCase support team "supported" snapshot views. Crying or Very Sad

Thanks for the idea, though!

bah..who needs support Smile

*cough*"cleartool mkview -snapshot -tag $snapshot \\$localmachine\views\$snapshotviewname.vws"*cough on windows*

If they don't support snapshot views, they just made clearcase into an scm system you can't build large products with as you experienced.

cleartool mkview
cleartool: Error: View directory pathname must be specified.
cleartool: Error: View tag must be specified.
Usage: mkview -tag dynamic-view-tag [-tcomment tag-comment] [-tmode text-mode]
              [-region network-region | -stream stream-selector]
              [-shareable_dos | -nshareable_dos] [-cachesize size]
              { -stgloc {view-stgloc-name | -auto}
              | [-host hostname -hpath host-stg-pname -gpath global-stg-pname]
                dynamic-view-storage-pname
              }
       mkview -snapshot [-tag snapshot-view-tag]
              [-tcomment tag-comment] [-tmode text-mode]
              [-cachesize size] [-ptime] [-stream stream-selector]
              [ -stgloc view-stgloc-name
              | -colocated_server [-host hostname -hpath host-snapshot-view-pname -gpath global-snapshot-view-pname]
              | -vws view-storage-pname [-host hostname -hpath host-stg-pname -gpath global-stg-pname]
              ] snapshot-view-pname

I don't have permission to create views myself. The ClearCase team keep complete control over everything. If they didn't do that people could get their job done without ringing them all the time. Then maybe they'd be redundant - and they'd never want that!

And even if clearcase could be worked around, you would still have to change all the .project files to remove the linked resource output. It doesn't fix the problem that Buckminster is not resolving linked resources properly.

I can trivially remove all the entries from all the .project files with a script. But yes, as Alan says, this is something broken that is very simple to patch in basic support for.
