Inheritance Error in Object List Configuration for Custom Plugin
----------------------------------------------------------------
Key: MNG-4819
URL: http://jira.codehaus.org/browse/MNG-4819
Project: Maven 2 & 3
Issue Type: Bug
Components: Inheritance and Interpolation
Affects Versions: 2.2.1
Environment: Windows XP SP3, running under Cygwin bash shell
Reporter: Jonathan Pearson
Attachments: bugdemo.tgz
When a parent defines an object list in a plugin configuration, and then a
child of that parent also defines an object list for the same plugin leaving
some values undefined (so as to use defaults), the object list is loaded into
the plugin in an unpredictable manner, sometimes using parent-defined
properties instead of defaults, and sometimes not.
The attached plugin/parent/child projects produce this incorrect output:
$ mvn inherit_bug_demo:bugdemo
...
[INFO] Configuration: [InheritanceBugDemoMojo: objects='[[DemoObject:
prop1='Child Object 1 Property 1', prop2='Property 2'], [DemoObject:
prop1='Parent Object 1 Property 1', prop2='Child Object 2 Property 2']]']
The expected output would either be:
[INFO] Configuration: [InheritanceBugDemoMojo: objects='[[DemoObject:
prop1='Child Object 1 Property 1', prop2='Parent Object 1 Property 2'],
[DemoObject: prop1='Parent Object 1 Property 1', prop2='Child Object 2 Property
2'], [DemoObject: prop1='Parent Object 3 Property 1', prop2='Parent Object 3
Property 2]]']
Or:
[INFO] Configuration: [InheritanceBugDemoMojo: objects='[[DemoObject:
prop1='Child Object 1 Property 1', prop2='Property 2'], [DemoObject:
prop1='Property 1', prop2='Child Object 2 Property 2']]']
See attached build log, demonstration plugin, and parent/child project for
details.
Usage:
$ cd inherit_bug_demo
$ mvn deploy
$ cd ../child
$ mvn inherit_bug_demo:bugdemo
