Re: [tycho-user] build speed?
|
Speaking of patches. I think it would be extremely useful if somebody
contributed Tycho performance regression test(s) and helped with
required hardware to run them on. We had pretty bad performance
regression right before 0.14 [1], which luckily got noticed (thank you,
Steffen!), but we can't rely on luck to catch all such regressions.
If anyone wants to volunteer, I think Maven performance regression tests
[2] can be used as a reasonable starting point.

The whole target platform/dependency resolution is not really an easy
subject, so probably not a good starting point in case you wanted to
contribute a patch.

You could try the offline mode that is now supported by 0.14.0

Hi,
I'm looking for ways to speed up my build.
I have a Tycho project with around 10 subprojects each of which has 5-10
bundles in them. I specify all my project dependencies in the root pom.
The rest of the poms just specify they are "eclipse-plugin"s. Likewise
for build plugins.
Running "mvn -o package" takes around 2 1/2 minutes. About 1 1/2 of
those are spent on Tycho's dependency, class path, and target platform
resolution. It seems like dependency resolution is slow, but then I
don't know the complexity of what is being done.
I've created a "release" profile that handles creating products & zips
for all our target platforms. This helped quite a bit for normal builds.
What are some good ways to speed up the build?
Thanks,
Matt

"Legacy code" often differs from its suggested alternative by actually
working and scaling.
