To prevent potential security risks, MPS lets you decide how to open a project if you're not sure about its source. MPS warns you about tasks or configurations that will be executed during the opening process and lets you configure sources that you can trust.
Open a project from unknown sources
When you open any project, MPS immediately lets you decide how to handle a project that contains unfamiliar source code.
You can select one of the following actions:
Trust Project: in this case, MPS opens and loads a project. That means project is initialized, project's plugins are resolved, dependencies are added, and all MPS features are available.
Don't Open: in this case MPS cancels the action.
You can configure what sources MPS should consider safe and load such projects automatically during the opening process.
You can add your home directory to the trusted locations to disable MPS's warnings about untrusted projects.
Configure trusted locations
In the Settings/Preferences dialog (Ctrl+Alt+S), go to .
On the Trusted Locations settings page, configure the local directories where the projects you consider trusted reside. Click OK to save the changes.
The next time you open a project from one of those locations, MPS will automatically load the project.
