如何在Visual 2017解决方案中包含proxygen的“目标”文件夹?

我已经使用jni4net proxygen从Java到.NET成功生成了代理。我现在正在尝试在Visual Studio 2017中创建.NET解决方案,并在.NET控制台程序中使用Java代理。我已从proxygeneration导入.dll,并且似乎可以正常运行,因为Visual Studio正在自动填充Java类(TempClientMain),并且未显示任何错误。

namespace ConsoleApp1
class Program 
{
     static void Main() 
     {
         var setup = new BridgeSetup(string[] args);
         setup.Verbose = true;
         setup.AddAllJarsClassPath("./");

         Bridge.CreateJVM(setup);
         Bridge.RegisterAssembly(typeof(TempClientMain).Assembly);

         TempClientMain test = new TempClientMain();
         test.run();
     }
}

但是当我构建并运行它时,我得到以下cmd输出:

它加载正常,但似乎找不到目标文件夹。我写了我的目标程序包路径的地方,显示了与proxygens目标文件夹相同的程序包路径(没有大写字母)。我应该把它放在哪里,以便.NET程序可以找到它?我尝试将文件夹粘贴到项目根目录和完成的构建文件夹中。当完全不包含错误时,也会出现错误。我对Visual Studio不太熟悉,所以除了粘贴它以包含它之外,还有另一种方法吗?

我只是从Java项目的build输出文件夹中丢失了一个jar文件。令人困惑的是,程序包路径根本没有引用该jar文件,但是可以添加它。
