File Path Problem in Plugin Development [message #623956] Fri, 19 March 2010 12:07 Go to next message

Hi everyone,

I am having the problem of getting the path of certain file in a plugin development.

In the initial Eclipse, I created the plugin project - PluginA:

PluginA
- AcitonHandler.java
- file1
- file2

What I want to do now is that I want to access the file1 and file2 in AcitonHandler.java. However, I do not know how to get the relative path of the PluginA folder.

I checked some of the messages, but most of them are about getting the path in the runtime-eclipse environment, not the parent Eclipse environment. Therefore, the desired result is that when ActionHandler.java is triggered in the runtime-Eclipse, it can access the file1 and file2 in the parent Eclipse folder.

Thanks a lot.

Yu

You need to use the class org.eclipse.core.runtime.FileLocator., the reason being that it knows how to read files within jar files, and if your plug-ins are jarred this is the only way to read the contents.

Here is a typical sequence:

Bundle bundle = Platform.getBundle(pluginId);
URL contentURL = FileLocator.find(bundle, new Path(path), null);

// call openStream() from the URL to get an input stream
