Hi,

You can revert all changes to the last committed state or follow this documentation:

Version Control

 

 

Hope it helps.

Hi jayasree,

                

🔹 Step 1: Close Mendix Studio Pro completely

Make sure Mendix is fully closed (no background process in Task Manager).

🔹 Step 2: Go to your project directory

Navigate to your local project folder (something like):

C:\Users\<username>\Documents\Mendix\<your_app_name>\

🔹 Step 3: Delete temporary folders

Delete the following folders if they exist:

deployment theme-cache userlib-cache

These will be regenerated automatically.

🔹 Step 4: Restore the .mpr file

Check whether your project’s .mpr file exists inside the folder.If it’s missing or corrupted:

Go to your Team Server project folder (<projectname>.mpr might exist there).

Or open Mendix Team Server → Version Control → Revert to last committed version.

🔹 Step 5: Revert using version control (Git)

If you’re using Team Server (Git):

Open Mendix Studio Pro.

Choose Version Control → Download from Version Control Server.

Select your app and re-clone it to a new folder (e.g. MyApp_fixed).

This ensures all missing .mprcontent files are re-downloaded.

🔹 Step 6: Check .mpr and .mprcontent file paths

The path in the error suggests the .mpr file expects its corresponding .mprcontent files under:

<ProjectFolder>\mprcontents\<GUID>.mprcontent

If these files are missing, they must be fetched again via revert or clone.

🔹 Step 7: Optional — Repair Mendix installation

If the issue persists across multiple projects:

Open Add or Remove Programs → Mendix 10.24.4 → Repair.

Then re-open your project.

Hello, 

 

Try to Close Studio Pro, delete the deployment, project, and javasource folders, then reopen the app to rebuild them. If it still fails, revert to the last committed version or do a clean checkout from SVN/Git to restore missing files.

Hi Jayasree,

Looks like your mpr file got corrupted.

Here's what you can do,

 

Open the git-bash into the directory of the project explorer,

Now type this command:

 

git reflog

This will give you the list of all the committed versions of your local git file,

the list will look something like this

Head{0}, Head{1}, along with the commte messge

 

Now, select the version which you want to revert to,

 

and use the command:

git reset --hard ( commit version)

so suppose, you want to revert to Head{0}

So the command will be:

git reset --hard Head{0}

This will revert your mpr file to last committed version, and you will be able to open your application.

 

Let me know, if you face any issues,

Hope it helps!
