如何获取Eclipse项目资源管理器中的完整文件路径？

Question

I am working on eclipse plugin. In this i have a file name present in a project hierarchy. i need the full path of file abc.java present in project Test.

The file presented in path F:/Test/src/main/java/com/sung/Pre/abc.java

    IWorkspaceRoot rootWorkspace = ResourcesPlugin.getWorkspace().getRoot();
    IProject project = rootWorkspace.getProject("/Test");
    file1 = project.getFile("/abc.java");

    FileEditorInput fileEditorInput = new FileEditorInput(file1);

    IWorkbench workbench = PlatformUI.getWorkbench();
    IEditorDescriptor desc = workbench.getEditorRegistry().getDefaultEditor(file1.getName());
    IWorkbenchPage page11 = workbench.getActiveWorkbenchWindow().getActivePage();

    try {

        page11.openEditor(fileEditorInput, desc.getId(),true);
    } catch (PartInitException e1) {
        e1.printStackTrace();
    }

This is searching file in /Test folder. If the file presented in the root Test folder it's able to open this file but if it's inside some folder like F:/Test/src/main/java/com/sung/Pre/abc.java than it's can not find the file.

I also tried below code but facing the same issue

    try {

        //IDE.openEditor(page11, uri, "org.eclipse.ui.ide.IDE", true);
        IDE.openEditor(page11, file1, true);
    } catch (PartInitException e2) {
        // TODO Auto-generated catch block
        e2.printStackTrace();
    }

so my question is if we have a file name presented in project hierarchy so how can we get the absolute or full path of that.

Please remember that i am doing this task in eclipse plugin project

You can specify a path on project.getFile :

project.getFile(new Path("src/main/java/com/sung/Pre/abc.java"));

or get the IFolder for the folder containing the file and use

folder.getFile(new Path("abc.java"));
