source-path mismatch problem

I'm trying to integrate unit testing with our build process and failing with the following error message.

BUILD FAILED

C:\Projects\project\client\FUTest\build.xml:88: Compilation failed: Warning: Source path entry, 'C:\Projects\project\client\FUTest\src\tests', is a subdirectory of source path entry, 'C:\Projects\project\client\FUTest\src'.

C:\Projects\project\client\FUTest\src\tests\SampleCase.as: Error: A file found in a source-path must have the same package structure '', as the definition's package, 'tests'.

C:\Projects\project\client\FUTest\src\tests\SampleSuite.as: Error: A file found in a source-path must have the same package structure '', as the definition's package, 'tests'.

I realize that my project structure does not match the sampleCIProject but I'm trying to fit this into an existing project that also does not match.

Here's the structure

FUTest/src/main/FlexUnitApplication.as

package main
{     public class FlexUnitApplication extends Sprite     {          public function FlexUnitApplication()          {               onCreationComplete();          }                   private function onCreationComplete():void          {               var testRunner:FlexUnitTestRunnerUIAS=new FlexUnitTestRunnerUIAS();               testRunner.portNumber=8765;               this.addChild(testRunner);               testRunner.runWithFlexUnit4Runner(currentRunTestSuite(), "FUTest");          }                   public function currentRunTestSuite():Array          {               var testsToRun:Array = new Array();               testsToRun.push(Request.methods(SampleCase,["simpleAdd"]));                             return testsToRun;          }     }
}

FUTest/src/main/FlexUnitCompilerAppliaction.as

package main
{     import flash.display.Sprite;     import tests.SampleCase;     import tests.SampleSuite;     public class FlexUnitCompilerApplication extends Sprite     {          private var tests_SampleCase_obj:SampleCase;          private var tests_SampleSuite_obj:SampleSuite;     }
}

FUTest/src/test/SampleSuite.as

package tests
{     [Suite]     [RunWith("org.flexunit.runners.Suite")]     public class SampleSuite     {          public var t1:SampleCase;     }
}

FUTest/src/test/SampleCase.as

package tests
{     import flexunit.framework.Assert;     public class SampleCase     {          [Test(description="My First Actionscript Unit Test")]          public function simpleAdd():void          {               var x:int = 5 + 3;               Assert.assertEquals( 8, x );          }     }
}

The initial complile seems works fine and produes bin/FUTest.swf.  So why does the flexunit compile fail?

Any help most appreciated.

Thanks,
