Re: Speed of Maven build

this would be an interesting use case for a native image, but the modular nature of maven is at the same time also the worst case scenario for native images :) best regards, -michael On 06.09.20 06:43, Jaroslav Tulach wrote: Thanks Jesse, Tim. I've modified https://issues.apache.org/jira/brow

Re: Speed of Maven build

For larger multi-module projects, I'd tend to suspect that a substantial chunk of the time is I/O-bound, parsing XML - build one project with a substantial dependency tree. How many POM files both in the project and under ~/.m2 need to parsed? It would be interesting to instrument Maven and get s

Re: Speed of Maven build

I think that your conclusions are reasonable. I've built your test project, that confirms the startup delay hypothesis. However performances must be evaluated on specific test cases : building a 10 *.java program is different from building CXF (maven) or derby (ant). Maybe that also the goals ar

Re: Speed of Maven build

Sorry to be late, but     there is a project test case for Maven "slowlyness" ? I mean : a project for which there's a time gap between - nb/command line mvn invocations - or between ant / mavn builds (I know : how many projects have TWO build files ? ...) for routinely rebuilds of big projec

Would multi threading/multi core parameters help speed things up? https://stackoverflow.com/questions/32368976/ways-to-make-maven-build-faster/44646756#44646756 Or other speedups like limiting some activities or profile the builds? https://medium.com/@alex_collins/10x-faster-maven-builds-at-intu

Re: Speed of Maven build

Also the M2Eclipse integration does basically embed maven and make the Maven build incremental. The Takari plugin does that on the commandline with the eclipse compiler And the VS code integration from Red Hat might also do something along those lines. Others can chime in with more details. M

Re: Speed of Maven build

Are you planning to create a baseline project or selecting a range of projects to be used as a baseline, so that perceived improvements can be monitored? So that anyone wanting to help out or give feedback can submit their own build performance. i.e. 1. Equipment OS, Ram, CPU, physical, virtual, d

In case this helps, Jason Dillon has a "Maven Shell" that does what you seek for CLI - launches a Maven instance and runs interactive commands with it, saving the startup time. https://github.com/jdillon/mvnsh On Tue, Aug 25, 2020 at 12:27 AM Jaroslav Tulach wrote: > > And it's Apache Maven, ov
