Re: [PROPOSAL]Provide an option to generate stubs in in-momery file system for better compiling performance

If we keep stubs in memory, IDE's incremental compiler can reuse them if no changes happen. I think builds of large groovy projects like Grails, Gradle and Groovy itself, etc will get more benefits from the new feature. Cheers, Daniel.Sun - Apache Groovy committer Blog: http://blog.sunl

Agreed. I find we can get rid of the 3rd-part lib and just rely on `javax.tools` APIs, e.g. ``` compilationUnits.add(new MemJavaFileObject(new URI("string:///labs/Hello.java"), srcStr)); ``` I'm doing some experiment. Cheers, Daniel.Sun - Apache Groovy committer Blog: http://blog.sunlan

This would be indeed very useful. The current join compilation tend to be time consuming. p On Fri, Jan 18, 2019 at 9:44 AM Daniel Sun wrote: > Hi all, > > [Background] >Groovy's joint compiler will generate a lot of stubs for groovy > source files, many of the stubs are useless and wri

It's an interesting idea. I like that it's hidden behind a flag, because sometimes you want to keep the stubs. That must be the case for IDEs that implement "some kind" of incremental compilation. Le ven. 18 janv. 2019 à 09:44, Daniel Sun a écrit : > Hi all, > > [Background] >Groovy's jo

2019-01-18 Thread Daniel Sun
Hi all, [Background] Groovy's joint compiler will generate a lot of stubs for groovy source files, many of the stubs are useless and written to disk and clean later. When project contains a lot of groovy source files, the performance of compiling is not good. [Proposal] I propose to
