for my custom editor I want to add a marker, but got an exception. The exception is Resource '/c/runtime-EclipseApplication/HelloWorld/hello.me' does not exist. But res is not null, any idea?
public static IPath getPathFromEditorInput(IEditorInput input) {
if (input instanceof ILocationProvider)
return ((ILocationProvider) input).getPath(input);
if (input instanceof IURIEditorInput) {
URI uri = ((IURIEditorInput) input).getURI();
if (uri != null) {
IPath path = URIUtil.toPath(uri);
if (path != null)
return path;
}
}
return null;
}
@Override
protected void editorSaved() {
IPath path = getPathFromEditorInput(getEditorInput());
try {
createMarker(ResourcesPlugin.getWorkspace().getRoot().getFile(path), 2);
}
catch (CoreException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
super.editorSaved();
}
public static IMarker createMarker(IResource res, int line) throws CoreException {
IMarker marker = null;
// note: you use the id that is defined in your plugin.xml
if (res != null) {
marker = res.createMarker("com.mymarker");
marker.setAttribute(IMarker.SEVERITY, 0);
marker.setAttribute(IMarker.CHAR_START, 10);
marker.setAttribute(IMarker.CHAR_END, 20);
marker.setAttribute(IMarker.LOCATION, "Snake file");
marker.setAttribute(IMarker.MESSAGE, "Syntax error");
}
return marker;
}
Here is snippet from plugin.xml
<extension point="org.eclipse.core.resources.markers"
id="com.mymarker"
name="ME errors">
<super type="org.eclipse.core.resources.problemmarker" />
<super type="org.eclipse.core.resources.textmarker" />
<persistent value="true" />
</extension>
CodePudding user response:
ResourcesPlugin.getWorkspace().getRoot().getFile(path)
requires a path which is relative to the workspace root, you are giving it an absolute file path.
Use getFileForLocation
for a full path:
ResourcesPlugin.getWorkspace().getRoot().getFileForLocation(path)
Also note that if the IEditorInput
is an instance of IFileEditorInput
then you can get the IFile
using IFileEditorInput.getFile()
