Re: [january-dev] Newbie using January

[Jonah Graham <jonah@xxxxxxxxxxxxxxxx>]

Hi Scott,

Unless I am misunderstanding, adding the following to your target file
will mean you can consume from the p2 directly without needing
features. The p2 meta info has all the dependency info needed.

<location includeMode="planner" includeAllPlatforms="false"
includeSource="true" includeConfigurePhase="false"
type="InstallableUnit">
<unit id="org.eclipse.january" version="0.0.0"/>
<repository id="january-1_0"
location="http://download.eclipse.org/january/releases/1.0.0/repository/"/>
</location>

Or if you are using TPD files, you can do this:

location "http://download.eclipse.org/january/releases/1.0.0/repository/";
january-1_0 {
org.eclipse.january lazy
}

The above snippets are from the example here
https://github.com/eclipse/january/tree/JANUARY_1_0_0/org.eclipse.january.examples

As for Source-Reference header, that is just a bug in our build AFAIK,
issue raised: https://github.com/eclipse/january/issues/55

Thanks,
Jonah
