        this instance

      • setAggressive

        Whether to use aggressive mode or not. If set to true JGit behaves more similar to native git's "git gc --aggressive". If set to true compressed objects found in old packs are not reused but every object is compressed again. Configuration variables pack.window and pack.depth are set to 250 for this GC.
        Parameters:
        aggressive - whether to turn on or off aggressive mode
        Returns:
        this instance
