Hello guys,
I would need your help with karaf-maven-plugin, please.
I cannot find out the minimal version of Maven which is required to use
karaf-maven-plugin:features-generate-descriptor goal (in version 4.0.7).
In the Karaf docs, the only mention of Maven version is in the "4.1.4.
Building from Sources" section
(http://karaf.apache.org/manual/latest/#_building_from_sources), which
states:
Apache Maven 3.0.4 or greater
We've migrated to Karaf 4.0.7 and that version of the karaf-maven-plugin
and our build with Maven 3.0.5 (on our CI server, as locally no one is
using Maven 3.0 :-)) fails with a ClassCastException (I am appending the
stacktrace at the end of this message).
Seems the changes for https://issues.apache.org/jira/browse/KARAF-884 (
https://github.com/apache/karaf/commit/2d96f914382423762f86c3432587510247beb955
) have broken the compatibility with Maven 3.0.x as it introduced into
GenerateDescriptorMojo.java the usage of the
org.eclipse.aether.artifact.DefaultArtifact class which is not compatible
with Maven 3.0.
Would you let me know, if this was on purpose and now the minimal Maven
version required to use the plugin is 3.1.x or this is a kind of
side-effect/regression?
Thank you in advance!
Kind regards
Sergiy
