Question

In my plugin de.support.help are the plugin.properties files.
These properties files include the strings for the preference page.

I want to use this plugin for different customers, but the customer name is inside the properties files.

I want to patch the properties files by using the eclipse fragment mechanism. As far as i now the fragment plugin can patch the coresponding plugin at runtime.

I do have the file plugin.properties in plugin de.support.help which includes the line

plugin.name = Copyright XYZ

And i do have the fragemt de.support.help.fragment which includes the file plugin.properties with line

plugin.name = Copyright ABC

I expect that at runtime the string “Copyright ABC” is shown, but it is not. I had tested the same with java classes a long time ago and i remember that t his was working. The java code from the fragment was placed to the original plugin.

Do you have any idea to handle this? Or do i misunderstand the fragment mechanism?

Thanks

EDIT:

When i remove the plugin.properties file from the de.support.help plugin it works as expected. The fragment file is copied into the plugin directory and is used at runtime.

Or do i have to patch the somce eclipse class Can_fragments_be_used_to_patch_a_plug

Answer 1

The solution i have implemented is like

First look for special fragment property file and than look for the default property file.

The code is (Bundle names were changed)

public final class FrameworkMessages {
    private static final String BUNDLE_NAME = "de.rts.messages"; //$NON-NLS-1$

    private static final ResourceBundle RESOURCE_BUNDLE = ResourceBundle.getBundle(BUNDLE_NAME);

    private static final String BUNDLE_FRAGMENT_NAME = "de.rts.fragment"; //$NON-NLS-1$


    private FrameworkMessages() {
    }

    public static String getString(String key) {
        try {
            return ResourceBundle.getBundle(BUNDLE_FRAGMENT_NAME).getString(key);
        } catch (MissingResourceException e) {
            // Use messages in this plugin when no external fragment files can found
        }

        try {
            return RESOURCE_BUNDLE.getString(key);
        } catch (MissingResourceException e) {
            return '!' + key + '!';
        }
    }

    public static String getString(String pKey, Object[] pArgument) {
        try {
            return MessageFormat.format(RESOURCE_BUNDLE.getString(pKey), pArgument);
        } catch (MissingResourceException e) {
            return '!' + pKey + '!';
        }
    }
}
