Hi,

You’re right, the module file isn’t correct. This line should be in there:

```auto
<jar scope="G">simpletagprovider.jar</jar>
```

Also, for what it’s worth, there’s a bug in the example. On line 130, instead of:

```auto
for (int i = currentTagCount; i > newCount; i++) {
```

it should be:

```auto
for (int i = currentTagCount; i > newCount; i--) {
```

Maybe we do these things to keep people sharp 😈😐
