If new or updated plugins are available, you can select, download, and install them using the Plugins manager. A plugin generally consists of a group of dependent modules. Some IDE plugins are grouped together and referred to as a Feature. Each Feature generally corresponds to a technology and can contain a number of plugins that support that technology. When you activate or deactivate a Feature, the IDE activates or deactivates the corresponding plugins.

When you update a plugin, the update usually consists of updating one or more of the modules that make up the plugin. Some plugins may be dependent on modules in other plugins in order for the functionality to be implemented.

The Plugins manager warns you when this is the case. Deactivating a plugin usually consists of deactivating the individual modules that make up the plugin.

When you use the Plugins manager to update the IDE, the IDE checks the registered update centers to see if there are new plugins or new versions of already installed plugins available. If new or updated plugins are available, you can select, download, and install the plugins using the Plugins manager. You can set the frequency that the IDE checks for updates in the Settings tab of the Plugins manager. The Plugin Installer will check for updates of installed in plugins.

The Replace String field also displays a preview of the internationalized string. If no resource bundle exists for the file, the Bundle Name and Replace String fields are empty. You can click the ellipsis If you want to add arguments to the method call, click Arguments. You can only add arguments to the method call if you use the java.

MessageFormat or org. Check that the key and value are correct. By default, the Internationalize dialog box gives the key the same name as the string being replaced. To get information about the highlighted string in the Source Editor, click Info to see the name of the component containing the string and the property that the string is associated with.

The Internationalization wizard enables you to replace hard-coded strings with internationalized strings in multiple files. If you are localizing the source into more than one language, the Internationalization wizard also lets you specify the localized string for multiple locales.

To automatically internationalize strings in multiple source files:. Click Add Source s to add one or more source files to internationalize. Click Next to proceed. Click Select All if you want a single resource bundle to contain the key and value pairs for all the listed sources. To select a resource bundle for specific source files, select the desired sources and click Select Resource.

In the Select Resource dialog box, select the desired. The Init String field gives you a preview of the code that the variable will use to reference the resource bundle. To change this code, click Format and select the desired code format from the Init Code Format Editor.
