LintError Unknown ID for Parallel Build

If I run a lint task as part of a parallel build, I get a LintError for each issue ID that Timber defines saying:

> Unknown issue id "The Timber Issue ID"

I disable all the Timber lint checks because I built my logging framework off Timber, and the checks are moot for my use case.

I have around 12 modules, but all the errors are in my app module. If I disable gradle parallel builds there is no error.

My `lintOptions`:

```
lintOptions {
lintConfig rootProject.file('lint.xml')
disable 'ParcelCreator', 'TimberExceptionLogging', 'LogNotTimber', 'StringFormatInTimber', 'ThrowableNotAtBeginning', 'BinaryOperationInTimber', 'TimberArgCount', 'TimberArgTypes', 'TimberTagLength'
}
```

My `lint.xml`:

```

```

One of the lint errors:

```

```

Start with the lint configuration in app/build.gradle at line 162 and the referenced rootProject lint.xml. Reproduce the lint task with Gradle parallel builds enabled and compare it with a non-parallel build, focusing on the Timber issue IDs listed in the configuration. Done means the parallel build no longer reports those IDs as unknown.
