[jira] [Commented] (NETBEANS-5755) give user better control of the
compiler caches
[ https://issues.apache.org/jira/browse/NETBEANS-5755?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17390109#comment-17390109 ]
Matthias Bläsing commented on NETBEANS-5755:
--------------------------------------------
I think you are not talking about a compiler cache, but about the indexing infrastructure of netbeans. If I remember correctly there is an API to force reindexing a complete tree (see org.netbeans.modules.parsing.api.indexing.IndexingManager), maybe you can come up with a simple plugin to add an option to refresh a broken index.

> Key: NETBEANS-5755
> URL: https://issues.apache.org/jira/browse/NETBEANS-5755
> Project: NetBeans
> Issue Type: Improvement
> Components: ide - Code
> Affects Versions: 12.4
> Environment: all, but in this case ubuntu 20.04, net 12.3 and 12.4 , java 11, OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.10+9, mixed mode)
> Reporter: Pieter van den Hombergh
> Priority: Major
>
> Caching is a hard problem. This rears it's ugly head in the way the IDE tries
> to speed up things by caching 'previous' compilation. It gets it wrong when invalidating or clearing the cache.
> The current approach is to keep the cache in a well known place (e.g .~/cache/netbeans/12.4/... under *NIX systems), for all project ever built with that IDE and version.
> The cache is a binary format, presumably for performance reasons.
> I would promote another approach:
> * Make the cache part of the project directory, e.g. below nbproject or something similar.
> The advantages would be that the user does not have to invalidate the whole cache (doing rm -fr of said well-known-place, but can instead just do rm -fr nbproject/cache/*. This could also be attached to a button label 'real clean'.
