This means that you can now build a product / feature made of multiple versions of the same bundle (given that they are not marked singleton).
How do you do that:
- In the feature.xml, identify the plugin and replace the 0.0.0 by the first three segments of the desired version followed by the string "qualifier". Example:
<plugin id="org.junit" version="3.8.1.qualifier" ... />
<plugin id="org.junit" version="4.1.0.qualifier" ... />
- In the map file, identify the plugin and add the first three segments of the version before the '=' sign (don't forget the comma)
plugin@junit,3.8.1=v20070301.....
plugin@junit,4.1.0=v20070301.....
Of course, if you don't use multiple versions you don't have to do anything new.
