                                          throws PackageCreatorException

      Default method to generate a pear package. With the given information first the installation descriptor is created and then the pear package is built.
      Parameters:
        `componentID` - Specify a componentID for this component
        `mainComponentDesc` - Specify the main component descriptor path that is used to start the component. The path must be specified relative to the `mainComponentDir` parameter.
        `classpath` - Specify the classpath for this component. Use macros like `$main_root` to specify the classpath entries.
        `datapath` - Specify the datapath for this component. Use macros like `$main_root` to specify the datapath entities.
        `mainComponentDir` - Specify the main component root directory that contains all the resources for the component. The mainComponentDir is packaged to the pear file.
        `targetDir` - Specify the target directory where the generated pear file is written to.
        `envVars` - Specify additional environment variables for the pear component. May also use macros like `$main_root` to specify the key values if necessary.
      Throws:
        `PackageCreatorException` - if an error occurs while create the pear package

    - #### createInstallDescriptor

          public static String createInstallDescriptor(String componentID,
                                                       String mainComponentDesc,
                                                       String classpath,
                                                       String datapath,
                                                       String mainComponentDir,
                                                       Properties envVars)
                                                throws PackageCreatorException

      Creates the installation descriptor with the given information and save it in the metadata folder of the `mainComponentDir`.
      Parameters:
        `componentID` - Specify a componentID for this component
        `mainComponentDesc` - Specify the main component descriptor path that is used to start the component. The path must be specified relative to the `mainComponentDir` parameter.
        `classpath` - Specify the classpath for this component. Use macros like `$main_root` to specify the classpath entries.
        `datapath` - Specify the datapath for this component. Use macros like `$main_root` to specify the datapath entities.
        `mainComponentDir` - Specify the main component root directory that contains all the resources for the component. The mainComponentDir is packaged to the pear file.
        `envVars` - Specify additional environment variables for the pear component. May also use macros like `$main_root` to specify the key values if necessary.
      Returns:
        Path to the created installation descriptor.
      Throws:
        `PackageCreatorException` - if an error occurs while creating the installation descriptor

    - #### createPearPackage

          public static String createPearPackage(String componentID,
                                                 String mainComponentDir,
                                                 String targetDir)
                                          throws PackageCreatorException

      create pear package based on the given information. This method can be called if a installation descriptor is already available or generated. The method will not generate the installation descriptor if it is not present.
      Parameters:
        `componentID` - Specify a componentID for this component
        `mainComponentDir` - Specify the main component root directory that contains all the resources for the component. The mainComponentDir is packaged to the pear file.
        `targetDir` - Specify the target directory where the generated pear file is written to.
      Returns:
        Retuns path absolute path to the created pear package.
      Throws:
        `PackageCreatorException` - if the pear package can not be created successfully.
