Add my plugin to new Java project classpath [message #1689435]

Hi,

I want to add my plugin jar file to a newly created Java project.

I am doing it with this code but I wonder if there is a better/cleaner way to do it. The path used seems to be likely to change once my plugin is updated, so any existing projects would be broken.

I thought maybe of adding a library variable and using something similar, so that the project references the library and will be correct if the path ever changes.

    URL url = new URL("platform:/plugin/" + MyPlugin.PLUGIN_ID);
    String path = FileLocator.toFileURL(url).getFile();
    IClasspathEntry pluginEntry = JavaCore.newLibraryEntry(new Path(path), null, null);

Have you seen the extension point "org.eclipse.jdt.core.classpathVariableInitializer"?

Also extension point "org.eclipse.jdt.core.classpathContainerInitializer" might be of interest.

In the first case you can declare classpath entries as "MYVAR/somePlugin.jar", whereas the second extension point allows to reduce it to "MYCONTAINER", avoiding also problems with version numbers that might be part of your plugin jar.

Thanks for the reply.

Is there a better way to get my plugin jar file path? The code sample I posted just gets the path to the plugin but it is for the classes, not for the jar itself. I think that a path to the jar would be cleaner.
