Trouble with -Xlint:all and maven

Question

I\'m trying to get maven to output lint level warnings. I\'ve created a small test program that should generate a warning about using a static method from a non-static context,

This "works for me" with your sources.

  4.0.0

  com.buck
  mavenproject3
  1.0-SNAPSHOT
  jar

  mavenproject3
  http://maven.apache.org

  
    UTF-8
  

  
    
      junit
      junit
      3.8.1
      test
    
  

  
    
      
        org.apache.maven.plugins
        maven-compiler-plugin
        3.0
        
          1.6
          1.6
          -Xlint:all
          true
          true
        
      
    
  

I imagine that the reason your commented out attempt with

is failing because of the XML namespace "Xlint" that the "all" tag would fall into, which means that the entire tag "Xlint:all" probably wasn't even seen by the maven configuration parser (being in a different namespace and all).

By the way, the relevant lines of output

Compiling 1 source file to C:\Users\edwbuck\Documents\NetBeansProjects\mavenproject3\target\classes
bootstrap class path not set in conjunction with -source 1.6
com/buck/mavenproject3/App.java:[12,35] static method should be qualified by type name, java.lang.String, instead of by an expression

and my environment

Apache Maven 3.0.4 (r1232337; 2012-01-17 02:44:56-0600)
Maven home: C:\Program Files\NetBeans 7.2.1\java\maven

Perhaps you stepped on a platform specific bug?
