Cannot control log4j when running all maven tests

Question

In src/test/resources/log4j.propertiesI configured log4j to not write anything.

When I run one test, i.e. mvn clean test -Dtest=MyTestClass, these log4j properties are taken into account. However, when I run all the tests, i.e. mvn clean test, this conf log is ignored. How can it be?!!

I think I'm going crazy, but hope a logical explanation :-)

Any help is appreciated.

One of the 52 test classes in src/test/javahad the following lines in the method @Before:

   import org.apache.log4j.BasicConfigurator;

   @Before
   public void setUp() {
     BasicConfigurator.resetConfiguration();
     BasicConfigurator.configure();
   }
