Where is M2_REPO ?
M2_REPO is present in classpath under Eclipse or Spring Tool Suite .
Window->Preferences->Java->Build Path -> Classpath
As we can see above M2_REPO is non modifiable , so How can we solve this error to change M2_REPO .
How to Solve the M2_REPO is non Modifiable
To modify the M2_REPO value, you need to change it at Eclipse’s Maven configuration page. Select Windows -> Preferences -> Maven -> User Settings.
