The Build Report view opens when you build a process, and shows the progress and details of the build process, including errors and warnings. Click a line in the Build Report view to select the corresponding step in the process editor. You can also copy selected lines or all the text from the Build Report view, and clear the contents from the view.
If you set the Build and Upload Preferences to display stack traces, they are included in the Build Report view as well, up to the maximum number of lines specified.
If you close the Build Report view and want to reopen it, go to Window > Show View > Other > Build Report.
