Tycho doesn't use SmartBuilder

Shouldn't Tycho use the Takari builder when the thread count is larger than 1? I never get the smart builder:

I've been debugging this, and I don't get into TychoGraphBuilder.java at all, where that builder would be configured via session properties. What needs to be done to use TychoGraphBuilder? Be aware I don't use the polyglott stuff, if that's relevant.

You need to enable tycho-build extension as described here as a first step, but you are using project mode according to the log output.

This is not mandatory, but things like smartbuilder can only be enabled in extensions mode.

Aaah, that makes sense now. 2 years ago I removed the extensions.xml because I thought that having the <extension>true</extension> flag would be sufficient, and then removing the otherwise useless file seamed cleaner.

Thanks @laeubi for the clarification.

There are two kinds of extensions:

• project extensions: that can extend things once projects are loaded, e.g. new packaging types, participate once session is finalized)
• core extension: that can extends almost everything including how projects are read/and or scheduled

of course if you only want to use smart-builder, you can also opt-in to enable it as a standalone extension, but in the light of Maven 4 Tycho will probably move towards requiring tycho-build anyways.
