Project generation problem using Spring Roo

I just downloaded SpringSource Tool Suite, and tried to generate a demo application using roo, but i'm getting error below

Code:

Created /home/dev/springsource/workspace/demo/pom.xml
Undo create /home/dev/springsource/workspace/demo/pom.xml
Invalid dependency scope: PROVİDED
[Timer-0] NullPointerException at org.springframework.roo.classpath.itd.AbstractItdMetadataProvider.notify(AbstractItdMetada开发者_JAVA技巧taProvider.java:84)

What is the problem? is this Maven issue?

Using: Ubuntu 8.10, SpringSource Tool Suite Version: 2.3.3.M1, Roo 1.1.0.M1, Apache Maven

Thanks

Try adding this to JVM arguments in roo.sh: -Duser.language=en

HTH

an addition; if you are using STS, you also have to add "-Duser.language=en" to sts.ini
