It throws following exception : System.AggregateException: One or more errors occurred. ---> Mendix.Modeler.Deployment.DeploymentException: Cannot start the packager. --- End of inner exception stack trace --- at System.Threading.Tasks.Task.ThrowIfExceptional(Boolean includeTaskCanceledExceptions) at System.Threading.Tasks.Task.Wait(Int32 millisecondsTimeout, CancellationToken cancellationToken) at Mendix.Modeler.WebUI.Deployment.Native.NativeDeploymentWorker.StartBundler(IProgressInfo info) in C:\jenkins-ci\workspace\AppStudio3.0-Build@3\modeler\Mendix.Modeler.WebUI\Deployment\Native\NativeDeploymentWorker.cs:line 123 at Mendix.Modeler.Deployment.DeploymentProcessBuilder.<>c__DisplayClass12_0.<AddBuildStepsForPhase>b__0(IProgressInfo info) in C:\jenkins-ci\workspace\AppStudio3.0-Build@3\modeler\Mendix.Modeler.Core\Deployment\DeploymentProcessBuilder.cs:line 123 at Mendix.Modeler.Deployment.FileIOExceptionHandlingProcess.CatchDiskException(Action action) in C:\jenkins-ci\workspace\AppStudio3.0-Build@3\modeler\Mendix.Modeler.Core\Deployment\FileIOExceptionHandlingProcess.cs:line 28 at Mendix.Modeler.Deployment.FileIOExceptionHandlingProcess.<>c__DisplayClass1_0.<AddStep>b__0(IProgressInfo info) in C:\jenkins-ci\workspace\AppStudio3.0-Build@3\modeler\Mendix.Modeler.Core\Deployment\FileIOExceptionHandlingProcess.cs:line 19 at Mendix.Modeler.UIFramework.Progress.ProcessRunner.RunStep(Step step) in C:\jenkins-ci\workspace\AppStudio3.0-Build@3\modeler\Mendix.Modeler.UIFramework\Progress\ProcessRunner.cs:line 80 at Mendix.Modeler.UIFramework.Progress.ProcessRunner.OnDoWork(Object sender, DoWorkEventArgs e) in C:\jenkins-ci\workspace\AppStudio3.0-Build@3\modeler\Mendix.Modeler.UIFramework\Progress\ProcessRunner.cs:line 60 at System.ComponentModel.BackgroundWorker.OnDoWork(DoWorkEventArgs e) at System.ComponentModel.BackgroundWorker.WorkerThreadStart(Object argument) ---> (Inner Exception #0) Mendix.Modeler.Deployment.DeploymentException: Cannot start the packager.<--- When I run the same application with Mx Model reflection package – 5.6.2 .
