Command line arguments don't overwrite settings.xml properties when invoking a
plugin
-------------------------------------------------------------------------------------
Key: MNG-3884
URL: http://jira.codehaus.org/browse/MNG-3884
Project: Maven 2
Issue Type: Bug
Components: Command Line
Affects Versions: 2.1.0-M1
Environment: All environments
Reporter: laurent gousenbourger
To explain the issue, let's start with the following example:
1°) Run a plugin goal with an argument specified in the command line with the
"-D" option only
mvn eclipse:eclipse -Declipse.projectNameTemplate=CommandLineProjectName
We can see if we open the generated .project file that the name of the project
is as we expect: "CommandLineProjectName"
This is normal, the goal input parameter is set with the command line property.
2°) Run a plugin goal with an argument specified in the "settings.xml" file only
mvn eclipse:eclipse
with settings.xml containing the following enabled profile:
<profiles>
<profile>
<id>testProfile</id>
<properties>
<eclipse.projectNameTemplate>SettingsProjectName</eclipse.projectNameTemplate>
</properties>
</profile>
</profiles>
<activeProfiles>
<activeProfile>testProfile</activeProfile>
</activeProfiles>
We can see if we open the generated .project file that the name of the project
is as we expect: "SettingsProjectName".
This is normal, the input parameter of the goal is set with the "settings.xml"
file property.
3°) Run a plugin goal with an argument specified in the command line with the
"-D" option and with another value in the "settngs.xml" file
If we use both scenarios, the property value set in the "settings.xml" file
will overwrite the value set via the command line with the "-D" option.
Maven should not react in that way but in the opposite: the command line value
should overwite the "settings.xml" file value.
It is already the case if we reuse the value somewhere in the pom.xml file. It
should be the same when invoking a plugin goal.
