Hi, My question is not about the version of feature, there is only one feature of version 1.0 (name='myfeature' version='1.0') defined in both two different features xml which I provided in the mail.
My question is: if a feature (same name and same version) exists in multi features repo xml, and all these features urls have been installed into karaf (using features:addurl), then, when I run: >features:install myfeature/1.0 Which one will be installed? The one from features_a xml? or the one from features_b xml? >From the result of my test, no matter the order of features:addurl commands >executed, the last one from the features:listurl will be installed into karaf. > Is it right? How to allow user to select his preferred myfeatu.re/1.0 to >install? Thanks.

The version of the feature that you offer when installing via Maven protocol (say, via command-line features:install) is what Karaf _searches_ for in available repositories, with ordering behavior undefined (howsoever the feature-version in Maven was defined). If you don't give a version in your install operation, it'll search for the latest non-snapshot in available repositories, with ordering behavior undefined. And just to be complete, if you use a feature version in a feature declared as a _dependency_ in feature XML, it has the second meaning. Is that right? Two different meanings, the first of which (defining the feature version) _only_ applies to the attribute in XML? --- A.
