[jira] Updated: (MPLUGIN-47) maven-plugin-tools-ant: faulty
variable interpolation
[ http://jira.codehaus.org/browse/MPLUGIN-47?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Benjamin Bentmann updated MPLUGIN-47:
-------------------------------------
Component/s: Ant Plugins
> maven-plugin-tools-ant: faulty variable interpolation
> -----------------------------------------------------
>
> Key: MPLUGIN-47
> URL: http://jira.codehaus.org/browse/MPLUGIN-47
> Project: Maven 2.x Plugin Tools
> Issue Type: Bug
> Components: Ant Plugins
> Environment: WinXP SP2
> Maven 2 SNAPSHOT
> Reporter: Michael Böckling
> Priority: Minor
>
> Using ANT as Mojo language, there is a bug in the variable interpolation.
> Example parameter:
> <!-- performexec -->
> <parameter>
> <description>Execute a binary</description>
> <name>performexec</name>
> <expression>${performexec}</expression>
> <required>false</required>
> <readonly>false</readonly>
> <type>java.lang.String</type>
> </parameter>
> Example Mojo call:
> <project>
> <target name="someproject">
> <taskdef name="someTask/>"
> <someTask performexec="${performexec}"/>
> ...
> Preconditions:
> - ${performexec} has no default value
> - ${performexec} is not marked as required
> - ${performexec} is not set in POM that executes the Ant Mojo plugin
> Observed behaviour:
> - The string "${performexec} " is literaly passed to the corresponding task.
> Expected result:
> - ${performexec} should be null.
> If the parameter has a <defaultValue></defaultValue> tag, above error occurs too. I'd expect that to set the parameter to the empty string (instead of null when leaving out <defaultValue></defaultValue>).
