comment with {@code} causes build_runner to crash

[dickermoshe]

There seems to be a bug in build_runner that any comment which contains this throws an error:

/// {@}
class A{}

/// {@hello}
class A{}

/// {@hello hi}
class A{}

Any comment with this will cause build_runner to give up:

[SEVERE] embed on lib/src/tz/android/bindings.dart:

This builder requires Dart inputs without syntax errors.
However, package:dateutil/src/tz/android/bindings.dart (or an existing part) contains the following errors.

Try fixing the errors and re-running the build.

[INFO] Running build completed, took 2.0s
[INFO] Caching finalized dependency graph completed, took 34ms

This is particularly troubling because jnigen put's many comments like this in the code because that's what java code has.

The error which is emitted is
/dateutil/lib/src/tz/android/bindings.dart(6..10): Doc directive 'hello' is unknown.
