A data analyzer for the Maven Central repository.
To build the JAR: mvn package
To run the JAR: java -jar <jar_name> (requires Java 17 or above)
When running the analyzer for the first time, a default configuration is created (config.yml).
To run a specific extractor, add the class to the extractors list.
The application expects extractor classses to implement nl.tudelft.mavensecrets.extractors.Extractor and have a public no-args constructor.
The thread pool size for the runner.
The application expects a PostgreSQL database.
Username and password can be omitted if the database does not require authentication.
The list of index files to read.
Index files are located in ./index-files/, and if absent will be downloaded from here.
The location of the local repository.
If omitted, $HOME/.m2/repository/ is used (the default local Maven repository location).
The seed variable is the number used as seed for the data selection to ensure reproducibility.
The sample-percentage variable is the sample size used.
To add a custom extractor, create an implementation for the Extractor class and add it to the configuration.
To add a custom data selection strategy, create an implementation for the PackageSelector class and change the selector used in App.java (currently unconfigurable).
Different repositories can be configured in the DefaultResolver, and additional configuration entries can be added in the config package.
