Can Acceleo be configured to overwrite exsisting files? I've tried the UML to Java example of Acceleo 3. It does not rewrite existing Java files.

What does it do then ? It generate a new copy of the java file ? send an error ?

Acceleo usually rewrite the file, it will just no remove a old generated file if you have changed the file name in your template.

There is also a [protected /] option to prevent rewriting piece of code.

Hi,

If you generate a file and then relaunch your generation, the old file will be overwritten. If the old file is not generated anymore, we won't delete it.
If you have a piece of code in a protected area, this code will be protected from the overwriting. The same apply for a piece of code with a JMerge tag (like @generated NOT) in the documentation if you are generating Java.
If you have deleted from your generator the protected, the code inside of the protected area of a previously generated file that would be overwritten will be saved in a ".lost" file.

You can see part of this behavior in the video n°8 starting at 7min28s here.
