[gentoo-soc] Weekly Report: Big Data Infrastructure and Maven Overlay in Week 3

[Zhang Zongyu]

Hello,

This week, I fixed some bugs of java-ebuilder and implemented some new
features.[1]
Now java-ebuilder is able to compare the maven version of a given
maven artifact and the requirement properly.
And it can read the variable "MAVEN_PROVIDE" and thus support the
category "java-virtual".

I have also mapped Gentoo packages to Maven artifacts with a
JSON-formatted lookup table so that java-ebuilder can make use of
Gentoo packages now.
After that, I updated the spark-overlay with the new java-ebuilder,
and it generates more packages than before since some out-of-date
Gentoo packages are now recognized.[2]

Next week, I will try to implement all features listed in my
repository [3], and try to emerge all the packages listed in the
overlay.

Regards,
Zhang Zongyu
