Re: [tycho-user] build speed?

The build performance issue is traced here:


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

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?

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