Web project doesn't apply the changes

I'm developing a web project in Eclipse. But every time I apply a change an error appears so the changes aren't applied. If I delete the "target" folder and go to project -> Clean, the changes are applied, but as soon I perform any changes again I receive the same error.

The error is on pom.xml as follows:

C:\Users\Tiago\Desktop\B2BWeb\target\classes\main\resources\web\html\partials\manageProducts.html (The requested operation cannot be performed on a file with a user-mapped section open) (org.apache.maven.plugins:maven-resources-plugin:2.6:resources:default-resources:process-resources)
