MSBuild appears to only use old output files for custom build tools

I have an ANTLR grammar file as part of a C# project file and followed the steps outlined in the User Manual.
<Project ...>
<PropertyGroup>
<Antlr3ToolPath>$(ProjectDir)tools\antlr-3.1.3\lib</Antlr3ToolPath>
<AntlrCleanupPath>$(ProjectDir)AntlrCleanup\$(OutputPath)</AntlrCleanupPath>
</PropertyGroup>
<ItemGroup>
<Antlr3 Include="Grammar\Foo.g">
<OutputFiles>FooLexer.cs;FooParser.cs</OutputFiles>
</Antlr3>
<Antlr3 Include="Grammar\Bar.g">
<OutputFiles>BarLexer.cs;BarParser.cs</OutputFiles>
</Antlr3>
</ItemGroup>
<Target Name="GenerateAntlrCode"
Inputs="@(Antlr3)"
Outputs="%(Antlr3.OutputFiles)">
<Exec Command="java -cp %22$(Antlr3ToolPath)\antlr-3.1.3.jar%22 org.antlr.Tool -message-format vs2005 @(Antlr3Input)" Outputs="%(Antlr3Input.OutputFiles)" />
<Exec Command="%22$(AntlrCleanupPath)\AntlrCleanup.exe%22 @(Antlr3Input) %(Antlr3Input.OutputFiles)" />
</Target>
<ItemGroup>
<!-- ...other files here... -->
<Compile Include="Grammar\FooLexer.cs">
<AutoGen>True</AutoGen>
<DesignTime>True</DesignTime>
<DependentUpon>Foo.g</DependentUpon>
</Compile>
<Compile Include="Grammar\FooParser.cs">
<AutoGen>True</AutoGen>
<DesignTime>True</DesignTime>
<DependentUpon>Foo.g</DependentUpon>
</Compile>
<!-- ... -->
</ItemGroup>
</Project>
For whatever reason, the Compile steps only use old versions of the code, no amount of tweaking appears to help.
