Can't compile Antlr4 in VS2010 or 12

[r...@aarnts.com]

I have some problems creating an app using Antlr 4. I have done the following:
• Create a C# console app
• Create the reference dir and added the Antlr4.0 runtime files to that dir.
• Unloaded the project and added the text as proposed by Sam
<PropertyGroup>
<!-- Folder containing Antlr4BuildTasks.dll -->
<Antlr4BuildTaskPath>$(ProjectDir)..\Reference\Antlr4</Antlr4BuildTaskPath>
<!-- Path to the ANTLR Tool itself. -->
<Antlr4ToolPath>$(ProjectDir)..\Reference\Antlr4\antlr4-csharp-4.0.1-SNAPSHOT-complete.jar</Antlr4ToolPath>
</PropertyGroup>
<Import Project="$(ProjectDir)..\Reference\Antlr4\Antlr4.targets" />
• Reloaded the project again
• Added a Antrl 4 Combined Grammar
• Compiled the app
The result is the following error:
Error 1 Unknown build error: Object reference not set to an instance of an object. ConsoleApplication1

The output window gives the following info:
C:\test3\ConsoleApplication1\Reference\Antlr4\Antlr4.targets(129,5): error AC1000: Unknown build error: Object reference not set to an instance of an object.

Can anybody please help me?

Hi Rob,

If you have a 64-bit operating system, can you make sure you have both the 32-bit and 64-bit editions of the JDK 1.7 installed? The next release of the C# target properly detects any version you have installed, but the current alpha release isn't as robust.

Thank you,
