Class Environment

java.lang.Object
clazzfish.monitor.util.Environment
public class Environment extends Object
This class provides some utilities for the access to the environment (e.g. the system properties).

If you need different environments (e.g. for testing) this class is no longer final to be able to derive from it. This class was copied from PatternTesting.

    • getLocalMavenRepositoryDir

      public static File getLocalMavenRepositoryDir() throws IOException

      IOException - Signals that an I/O exception has occurred.
