title: Creating msi or exe installer using setupbuilder plugin in gradle for .net project
body: <p>I have a .net project which I build using the MSBuild plugin for gradle. In the final task I want to create a .msi or .exe installer including the dll's from build step. The current gradle build script looks as follows:</p>
  
  <pre><code>    buildscript {
      repositories {
          mavenCentral()
          jcenter()
          maven {
              url "https://plugins.gradle.org/m2/"
          }
      }
  
      dependencies {
          classpath "com.ullink.gradle:gradle-msbuild-plugin:2.16"
          classpath "gradle.plugin.de.inetsoftware:SetupBuilder:1.8.0"
      }
  }
  
  apply plugin: 'msbuild'
  apply plugin: "de.inetsoftware.setupbuilder"
  
  msbuild {
  // Project solution file
      solutionFile = 'Test.sln'
  
      targets = ['Clean', 'Rebuild']
  }
  
  setupBuilder {
      vendor = 'MyOrg'
      application = "Test"
      appIdentifier = "Test"
      version = '1.0'
      licenseFile = 'license.txt'
      // icons in different sizes for different usage. you can also use a single *.ico or *.icns file
      icons = 'test.icns'
      // all files for all platforms
      from( 'testbuild' ) {
          include 'bin/Debug/*.dll'
      }
      bundleJre = 1.8
  }
  
  msi {
      // files only for the Windows platform
  
  }
  </code></pre>
  
  <p>When I run gradle msi, the error is - </p>
  
  <pre><code>Execution failed for task ':msi'.
  &gt; org.gradle.api.internal.file.copy.CopyActionExecuter.&lt;init&gt;(Lorg/gradle/internal/reflect/Instantiator;Lorg/gradle/internal/nativeintegration/filesystem/FileSystem;)V
  </code></pre>
  
  <p>I am using gradle 4.2.1 , wixtools, setupbuilder 1.8. Is there any dependency that I'm missing or something in the code block?</p>
