Cause: tried to access method org.gradle.api.tasks.Exec.exec()V from class XXXXXXX works in milestone-3, fails in 5 & 6

My gradle script calls visual studio to build. Visual studio after compilig calls back into the gradle script to complete part of the build (done this way so people can just use VS normally and get that second gradle step automatically)

but I get this error in later milestones…

We’ll need more information to help. Particularly the configuration of your exec task and the relevant part of the stack trace.

Let’s start with this… these tasks run in milestone 3, but not 5 or 6. milestone-4 also fails, but for a different reason (to do with the Visual Studio project calling back in to the same Gradle script that kicked it off… That one is apparently already a known issue.)

This chunk of Gradle is imported by a project-specific script that sets up the build in other ways and may explicitly define project.vsSolutionFile (but that isn’t necessary)

// ------------ Visual Studio ------------
  project.devenv = null;
project.vsSolutionFile=null;
  if( VS90COMNTOOLS )
    devenv = "$VS90COMNTOOLS/../ide/devenv.com"
      task visualStudioCleanDebug(type:VisualStudioExec) {
    mode = "Debug"
 clean = true;
}
task visualStudioCleanRelease(type:VisualStudioExec) {
    mode = "Release"
 clean = true;
}
task visualStudioClean( dependsOn: [visualStudioCleanDebug, visualStudioCleanRelease] )
  task visualStudioDebug(type:VisualStudioExec, dependsOn: 'buildGeneratedSource') {
    mode = "Debug"
}
task visualStudioRelease(type:VisualStudioExec, dependsOn: 'buildGeneratedSource') {
    mode = "Release"
}
  class VisualStudioExec extends Exec {
    public String vsSolutionFile
    public String mode = "Release";
    public boolean clean = false;
                public VisualStudioExec() {
        executable = project.devenv;
    }
    private updateArgs() {
  if( !vsSolutionFile && project.vsSolutionFile)
   vsSolutionFile = project.vsSolutionFile;
  if( !vsSolutionFile ) {
   list = []
   project.projectDir.eachFileMatch(~/.+\.sln/){ list<< it.name }
   if( list.size == 1 )
    vsSolutionFile = list[0]
   else if( list.size > 1 )
             throw new IllegalArgumentException( "Multiple 'sln' files found, set project.vsSolutionFile in your build.gradle: "+list)
  }
        if( !vsSolutionFile )
            throw new IllegalArgumentException( "Set project.vsSolutionFile in your build.gradle")
        if( clean )
            setArgs( [vsSolutionFile, "/Clean", mode ]);
        else
            setArgs( [vsSolutionFile, "/Build", mode ]);
    }
    void exec() {
        println( "************ In exec *************")
        updateArgs();
        super.exec();
    }
}

Do you have a stacktrace for the error? You can run Gradle with -s to get the stack trace.

What went wrong: Execution failed for task ‘:antJar’. Cause: tried to access method org.gradle.api.tasks.Exec.exec()V from class AntExec
Try: Run with --info or --debug option to get more log output.
Exception is: org.gradle.api.tasks.TaskExecutionException: Execution failed for task ‘:antJar’.
