Hi,
I'm trying to set programmatically a persistent marker on some files in
a project, but without success.
What I need to do is this: in my own special project there is one file
called "main file". Each other file in the project must remember the
name of this file. I want to set a custom marker on each file, having as
attribute name "mainFilePath", and value the path of the main file.
The main file will then have to be available in an action added to the
popup menu in the Resources Navigator.
What is happening is that everything works as long as I don't close the
project, but when I close it and open it again the marker is not
restored. It should be persistent, so what am I doing wrong?
Thanks,
RA
In the plugin I'm doing:
<extension
id="myfilemarker"
name="File Marker"
point="org.eclipse.core.resources.markers">
<persistent
value="true">
</persistent>
<attribute
name="mainFilePath">
</attribute>
</extension>
During the creation of the project, in a resource visitor I do:
IMarker marker = r.createMarker("myfilemarker");
marker.setAttribute("mainFilePath", theMainFile);
In the selectionChanged method of an IViewActionDelegate (the action in
the popup menu), I have:
public void selectionChanged(IAction action, ISelection selection) {
if (selection instanceof StructuredSelection) {
StructuredSelection structSel = (StructuredSelection)selection;
if (structSel.size() > 0) {
Object[] paths = structSel.toArray();
if (paths[0] instanceof IFile){
IFile selectedFile = (IFile)paths[0];
try{
IMarker[] markers =
selectedFile.findMarkers("myfilemarker", false,
IFile.DEPTH_ZERO);
if (markers.length > 0){
IMarker marker = markers[0];
String mainFileName =
(String)marker.getAttribute("mainFilePath");
System.out.println("main file is "+mainFileName);
}
}catch(Throwable t) {
t.printStackTrace();
}
}
}
}
}

The marker type that is passed to IResource.create is of the form
<plugin-id>.<extension-id>, so if your code is in a plugin called
com.xyz.foo, then your code should look like:
IMarker marker = r.createMarker("com.xyz.foo.myfilemarker");
