I’ve started a project and ca new omponent recently using Dev Studio 10.82.6231.10191024. Project internals were generated with a _create_project_root.cmd script.
Now the Build Home folder says an index is 11 days old, but some of original component’s entities have changed but I can’t refer to those dynamically. Clear and Refresh does not update components, but gives NRE :

If I manually remove cache from %AppData%\DeveloperStudio\10.82\var\cache\build_home_cache\<project_path>\ (just what Clear and Refresh does), it respawns on IDE start without a change. Even if I physically move component directories out from \source to which Build Home refers to, somehow that old cache gets back with the same [index 11 days old]. Cache is cached somewhere I can’t find...

 

Is there a way to get around that and rebuild that index?

I got back to the problem and found that a build_home_index.zip cached in %AppData% gets updated from BuildHome path. If I remove index from BuildHome, I get the actual content, but projection won’t find dynamic entities.

So the question is - how can I force BuildHome reindexing externally?
Refreshing from context menu throws null-pointer exception as above.

I tried to report an issue from Developer Studio, but got a message:
JIRA isue was not created because: gbglcrd10

So I’ll just post report here:
 

Steps to Reproduce

First of all, _create_project_root.cmd is called to create a new project folder. IFS Customization project is created for existing folder with Build Home folder provided. Build Home folder gets indexed and build_home_index.zip is created. Now I can browse components in that folder.

Later on, when I update contents of BuildHome, say, one of components gets customized and additional entities are added and I need to reference those in my projection; BuildHome displays same old index [index is ... days old].

Actual Behavior

I press Refresh Cache or Clear and Refresh Cache on BuildHome nothing happens and I get an error in Notifications tab which is a NullPointerException.

Expected Behavior

I would expect to build_home_index.zip recreated and display the actual contents, just like when I remove  build_home_index.zip from BuildHome.

Troubleshooting/Testing Steps Attempted

If I remove  build_home_index.zip from BuildHome, I see the actual content with all new entities in listed components, but projection wouldn't generate as there's no index found and entities are missing. When I tried to replace  build_home_index.zip from BuildHome with the one from %AppData%\DeveloperStudio\10.82\var\cache\build_home_cache\, the BuildHome displays the old outdated content and [index is 11 days old] changed to [index is 14 days old].

Workaround

So far, no workaround is found and no way to continue developing my component further.

You need to manually run create_project_root.cmd again after you have added/changed files to your build home. That is not done by Developer Studio.

Internally at IFS we have setup something called AutoBuilder which is a series of scripts that builds and installs our development environment on demand or scheduled. The last step in AutoBuilder runs the create_project_root.cmd script to make the build_home_index.zip up to date with the new BuildHome content.

Thank you very much, @Tomas Ruderfelt ! Your suggestion worked. Despite the Studio is showing [index not found] in red, I can now generate projection code and all the necessary dependencies are picked up.
I’ll then create a script to call that index rebuild from create_project_root.cmd.

Hi,

I am new with IFS DEV Studio. I am trying to build my project but I can’t because I continue to receive the message “The application server is empty, there is nothing to deploy!”.  Does anyone can help me? I am using IFS 9.

 

Thanks
