Hi~
My maven project has root pom.xml which consists of four sub modules such as
below directory structure.

• MavenDepTest
• pom.xml
• Module1
• src
• pom.xml
• Module2
• src
• pom.xml
• Module3
• src
• pom.xml
• Module4
• src
• pom.xml

The root pom.xml is defined with no <module> element. So, I execute a
command "mvn --reactor clean package" directly, then it's completed with no
error.
But, Hudson can't execute this environment.
I don't know why occuring below message.
My Maven version is 2.2.1 and Hudson is 1.330.
