README

Usage:

cd <dir with p2 repos under it>
find . -name content.jar | python gencomposite.py

It will generate the necessary xml files for a composite repo and you
can now use the directory as an updatesite.

gencomposite.py

from lxml import etree

import fileinput

repos = []

for line in fileinput.input():
   repos.append(line)
   
repository = etree.Element("repository", name="Auto-generated repo", type="org.eclipse.equinox.internal.p2.metadata.repository.CompositeMetadataRepository", version="1.0.0")

properties = etree.SubElement(repository,"properties")
    
children = etree.SubElement(repository, "children")
for rep in repos:
    etree.SubElement(children,"child", location=rep.replace("content.jar\n",''))

children.attrib["size"]=str(len(repos))

s = etree.tostring(repository, pretty_print=True)

print "Writing compositeContent.xml"
file = open("compositeContent.xml", "w")
file.write(s)
file.close()


repository.attrib["type"] = "org.eclipse.equinox.internal.p2.artifact.repository.CompositeArtifactRepository"

s = etree.tostring(repository, pretty_print=True)

print "Writing compositeArtifacts.xml"
file = open("compositeArtifacts.xml", "w")
file.write(s)
file.close()
