I get the following log message when trying to analyze a Maven multi-module project with tslint greater than 5.2.0:
[WARNING] TsLint reported issues against a file that isn't in the analysis set - will be ignored: <maven-module-name>/<module-relative-path-to-ts-file>
Seems like the working directory should be set to the current module in the Command instance created in TsLintExecutorImpl.getBaseCommand. This will definitely fix my problem.
