    • invoke

      public final int invoke(InvokerRequest invokerRequest)
      Description copied from interface: Invoker
      Invokes the Maven application using the provided InvokerRequest. This method is responsible for executing the Maven command or build process based on the information contained in the request.
      Specified by:
      invoke in interface Invoker
      Parameters:
      invokerRequest - the request containing all necessary information for the invocation
      Returns:
      an integer representing the exit code of the invocation (0 typically indicates success)

    • doInvoke

      protected int doInvoke(C context) throws Exception
      Throws:
      Exception

    • handleException

      protected InvokerException.ExitException handleException(C context, Exception e)

    • printErrors

      protected void printErrors(C context, boolean showStackTrace, List<Logger.Entry> entries, Logger logger)

    • createContext

      protected abstract C createContext(InvokerRequest invokerRequest)

    • validate

      protected void validate(C context) throws Exception
      Throws:
      Exception

    • pushCoreProperties

      protected void pushCoreProperties(C context) throws Exception
      Throws:
      Exception

    • pushUserProperties

      protected void pushUserProperties(C context) throws Exception
      Note: this method is called twice from doInvoke(LookupContext) and modifies context. First invocation when LookupContext.pushedUserProperties is null will push user properties IF key does not already exist among Java System Properties, and collects all they key it pushes. Second invocation happens AFTER PropertyContributor SPI invocation, and "refreshes" already pushed user properties by re-writing them as SPI may have modified them.
      Throws:
      Exception

    • settings

      protected Runnable settings(C context, boolean emitSettingsWarnings, SettingsBuilder settingsBuilder) throws Exception
      This method is invoked twice during "normal" LookupInvoker level startup: once when (if present) extensions are loaded up during Plexus DI creation, and once afterward as "normal" boot procedure.

      If there are Maven3 passwords presents in settings, this results in doubled warnings emitted. So Plexus DI creation call keeps "emitSettingsWarnings" false. If there are fatal issues, it will anyway "die" at that spot before warnings would be emitted.

      The method returns a "cleaner" runnable, as during extension loading the context needs to be "cleaned", restored to previous state (as it was before extension loading).

      Throws:
      Exception
