[p2-dev] generator and download.md5 for packed files

[Henrich Kraemer <henrich.kraemer@xxxxxxxxxx>]

From a directory containing features and plugins, I am using Jar Processor to pack the plugins.

Then I would like to make a P2 repository out of this. I only need an artifact repository here. My code invokes org.eclipse.equinox.internal.p2.metadata.generator.EclipseGeneratorApplication with the following arguments:
-publishArtifactRepository
-compress
-inplace
-reusePack200Files
-artifactRepository
file:/C:/p2test/input_artifacts/
-metadataRepository
file:/C:/p2test/input_artifacts/
-source
C:\p2test\input_artifacts

The output of artifacts.jar (see excerpt below) looks good except that I am surprised that the packed files do not have a download.md5 property. I would really want to have this property to enable integrity check the associated downloads. Should this be considered a bug? Is there a work-around?

Another aspect - probably benign - but surprising to me was that I had to specify a -metadataRepository argument for the task to generate <artifact elements> inside artifacts.jar. Is this expected?

Thanks,

Henrich
