| /** |
| * The framework to run. This is used if the bootLocation (-boot) is not specified. |
| * The value can be specified on the command line as -framework. |
| * Startup class for Eclipse. Creates a class loader using |
| * supplied URL of platform installation, loads and calls |
| * the Eclipse Boot Loader. The startup arguments are as follows: |
| * <dl> |
| * <dd> |
| * -application <id>: the identifier of the application to run |
| * </dd> |
| * <dd> |
| * -arch <architecture>: sets the processor architecture value |
| * </dd> |
| * <dd> |
| * -boot <location>: the location, expressed as a URL, of the platform's boot.jar. |
| * <i>Deprecated: replaced by -configuration</i> |
| * </dd> |
| * <dd> |
| * -classloaderproperties [properties file]: activates platform class loader enhancements using |
| * the class loader properties file at the given location, if specified. The (optional) file argument |
| * can be either a file path or an absolute URL. |
| * </dd> |
| * <dd> |
| * -configuration <location>: the location, expressed as a URL, for the Eclipse platform |
| * configuration file. The configuration file determines the location of the Eclipse platform, the set |
| * of available plug-ins, and the primary feature. |
| * </dd> |
| * <dd> |
| * -consolelog : enables log to the console. Handy when combined with -debug |
| * </dd> |
| * <dd> |
| * -data <location>: sets the workspace location and the default location for projects |
| * </dd> |
| * <dd> |
| * -debug [options file]: turns on debug mode for the platform and optionally specifies a location |
| * for the .options file. This file indicates what debug points are available for a |
| * plug-in and whether or not they are enabled. If a location is not specified, the platform searches |
| * for the .options file under the install directory. |
| * </dd> |
| * <dd> |
| * -dev [entries]: turns on dev mode and optionally specifies comma-separated class path entries |
| * which are added to the class path of each plug-in |
| * </dd> |
| * <dd> |
| * -feature <id>: the identifier of the primary feature. The primary feature gives the launched |
| * instance of Eclipse its product personality, and determines the product customization |
| * information. |
| * </dd> |
| * <dd> |
| * -keyring <location>: the location of the authorization database on disk. This argument |
| * has to be used together with the -password argument. |
| * </dd> |
| * <dd> |
| * -nl <locale>: sets the name of the locale on which Eclipse platform will run |
| * </dd> |
| * <dd> |
| * -nolazyregistrycacheloading : deactivates platform plug-in registry cache loading optimization. |
| * By default, extensions' configuration elements will be loaded from the registry cache (when |
| * available) only on demand, reducing memory footprint. This option will force the registry cache |
| * to be fully loaded at startup. |
| * </dd> |
| * <dd> |
| * -nopackageprefixes: deactivates classloader package prefixes optimization |
| * </dd> |
| * <dd> |
| * -noregistrycache: bypasses the reading and writing of an internal plug-in registry cache file |
| * </dd> |
| * <dd> |
| * -os <operating system>: sets the operating system value |
| * </dd> |
| * <dd> |
| * -password <passwd>: the password for the authorization database |
| * </dd> |
| * <dd> |
| * -plugins <location>: the arg is a URL pointing to a file which specs the plugin |
| * path for the platform. The file is in property file format where the keys are user-defined |
| * names and the values are comma separated lists of either explicit paths to plugin.xml |
| * files or directories containing plugins (e.g., .../eclipse/plugins). |
| * <i>Deprecated: replaced by -configuration</i> |
| * </dd> |
| * <dd> |
| * -plugincustomization <properties file>: the location of a properties file containing default |
| * settings for plug-in preferences. These default settings override default settings specified in the |
| * primary feature. Relative paths are interpreted relative to the directory that eclipse was started |
| * from. |
| * </dd> |
| * <dd> |
| * -ws <window system>: sets the window system value |
| * </dd> |
| * </dl> |
