Inside an Eclipse plugin, I'd like to open a file in editor.
I know the full package and class name
How can I determine the path of the .java file from this?
Take a look at IJavaProject.findType( name ) method. Once you have an IType, you can use getPath or getResource methods to locate the file. This method searches across a project and everything visible from that project.
To search the whole workspace, iterate through all the Java projects in the workspace, calling the findType method on each in turn.
You also need to know the source folder.
IProject prj = ResourcePlugin.getWorkspace().getRoot().getProject("project-name");
IFile theFile = prj.getFile(sourceFolder + packageName.replace('.','/') + className + ".java");
Generally you specify the file for an editor with an IFile. You can also ask an IFile for variants of the file's path.
I know this is a bit old but I had the same need and I had a look at how eclipse does it for stack trace elements (they have a hyperlink on them). The code is in org.eclipse.jdt.internal.debug.ui.console.JavaStackTraceHyperlink (the link is "lazy" so the editor to open is resolved only when you click on it).
What it does is it first searches for the type in the context of the launched application, then for in the whole workspace (method startSourceSearch) :
IType result = OpenTypeAction.findTypeInWorkspace(typeName, false);
And then opens the associated editor (method processSearchResult, source is the type retrieved above) :
protected void processSearchResult(Object source, String typeName, int lineNumber) {
IDebugModelPresentation presentation = JDIDebugUIPlugin.getDefault().getModelPresentation();
IEditorInput editorInput = presentation.getEditorInput(source);
if (editorInput != null) {
String editorId = presentation.getEditorId(editorInput, source);
if (editorId != null) {
try {
IEditorPart editorPart = JDIDebugUIPlugin.getActivePage().openEditor(editorInput, editorId);
if (editorPart instanceof ITextEditor && lineNumber >= 0) {
ITextEditor textEditor = (ITextEditor)editorPart;
IDocumentProvider provider = textEditor.getDocumentProvider();
provider.connect(editorInput);
IDocument document = provider.getDocument(editorInput);
try {
IRegion line = document.getLineInformation(lineNumber);
textEditor.selectAndReveal(line.getOffset(), line.getLength());
} catch (BadLocationException e) {
MessageDialog.openInformation(JDIDebugUIPlugin.getActiveWorkbenchShell(), ConsoleMessages.JavaStackTraceHyperlink_0, NLS.bind("{0}{1}{2}", new String[] {(lineNumber+1)+"", ConsoleMessages.JavaStackTraceHyperlink_1, typeName})); //$NON-NLS-2$ //$NON-NLS-1$
}
provider.disconnect(editorInput);
}
} catch (CoreException e) {
JDIDebugUIPlugin.statusDialog(e.getStatus());
}
}
}
}
Code has copyright from eclipse. Hopfully I'm allowed to reproduced it if this is mentionned.

I am trying to access the full repository history of an IFile object programatically from an Eclipse plugin. When the file has never been renamed or moved, the following code snippet works:
public long getFileHistoryTimestamp(IFile file, IProgressMonitor monitor, boolean lastModified) {
IProject project = file.getProject();
RepositoryProvider rProv = RepositoryProvider.getProvider(project);
long createdMillis, lastModifiedMillis;
if (rProv !=null) {
IFileHistoryProvider fhp = rProv.getFileHistoryProvider();
if (fhp != null) {
IFileHistory fHist = fhp.getFileHistoryFor((IResource) file,
IFileHistoryProvider.NONE, null);
IFileRevision[] revs = fHist.getFileRevisions();
Arrays.sort(revs, new Comparator<IFileRevision>(){
public int compare(IFileRevision o1, IFileRevision o2) {
return Long.compare(o1.getTimestamp(), o2.getTimestamp());
}
});
for (IFileRevision rev : revs) {
if (rev.getTimestamp() >= 0) {
createdMillis = rev.getTimestamp();
break;
}
}
if (revs.length > 0) {
lastModifiedMillis = revs[revs.length - 1].getTimestamp();
}
}
return lastModified ? lastModifiedMillis : createdMillis;
}
But, if the file has been moved (e.g. with a multi-module maven project to a new or different module/project), then the values returned above are only for the file in it's current location - i.e. it does not track any rename/moves. The same file in the Eclipse Team History view does track the full version history.
How can I access this full history within the Eclipse Team API?
This is what I tried, but it failed.And it alerted that 'org.eclipse .core .internal.File cannot be cast to org.eclipse.core.resource.IProject'.
public void runDefaultAction(IStructuredSelection selection) {
Object element = selection.getFirstElement();
if (element instanceof IFile) {
openFileAction.selectionChanged(selection);
openFileAction.run();
String selectedPathString = ((IFile) element).getFullPath().toString();
System.out.println(selectedPathString);
//get project absolute path
ISelectionService service = navigator.getSite().getWorkbenchWindow()
.getSelectionService();
IStructuredSelection selection1 = (IStructuredSelection) service
.getSelection("BIT_DEC.myNavigator");
IProject iproject = (IProject) selection1.getFirstElement();
String real_file_path = iproject.getLocation().toString();
System.out.println(real_file_path);
.....
it alerted that 'org.eclipse .core .internal.File cannot be cast to org.eclipse.core.resource.IProject'.
Because:
Corrected last 3 lines of your code.
if(selection1.getFirstElement() instanceof IFile) {
IFile file = (IFile) selection1.getFirstElement();
String real_file_path = file.getLocation().toString();
System.out.println(real_file_path);
}
IFile has a getLocation() method that gives you the full path directly.
Note: The selection returned by the selection service will generally be the same as the selection you are given. You can get the project from an IFile by calling its getProject() method.
I'm studying eclipse cdt plug-in development use gnuarmeclipse.
previous question.
I need to set or replace a file(such a linkerscript) in project explorer.
I know it change on project properties -> C/C++ Build -> Settings -> Tool Settings -> GCC C Linker -> General -> Script file(-T).
But I want, it execute on project explorer context menu.
See below.
1) Select LD(folder for only one linkerscript file) on Project Explorer.
2) Right click and select "Set Linker Script File" on context menu.
3) Select a file to set or replace on Open window.
This is setlinkerscript.java
public class setlinkerscript extends AbstractHandler {
public Object execute(ExecutionEvent event) throws ExecutionException {
// TODO Auto-generated method stub
IWorkbenchWindow window = HandlerUtil.getActiveWorkbenchWindowChecked(event);
Shell shell = new Shell();
FileDialog dialog = new FileDialog(shell, SWT.OPEN);
dialog.setFilterExtensions(new String[] {"*.x"});
String linkerscript = dialog.open();
System.out.println(linkerscript);
return null;
}}
I got a file location but I don't know where I set on eclipse.
Any API or method is there? or recommend documents.
I can't attach jpg for figure.. need more reputation point. Sorry!
Thanks in advance.
Oh finally, I did it myself. This is my answer.
Thanks stackoverflow and google.
But.. another problems coming... ㅜㅜ

I have check very long logs after each start of Tomcat (from Eclipse).
Does exist a plugin or editor that I can use inside Eclipse? At least it must have colored for errors, debug and info messages.
Thanks.
I would recommend using Log4j:
http://logging.apache.org/log4j/1.2/
http://en.wikipedia.org/wiki/Log4j
It works great with eclipse and has the color scheme built in. It's highly customizable, takes some time to figure out but it's worth it.
The code to do this is rather simple, aside from syntax coloring. Just start a plugin project, add dependancies for org.eclipse.ui.console and do something like this:
public void log() {
BufferedReader br = new BufferedReader(new FileReader("path of log file"));
String line = null;
while (br.nextLine ) {
line = br.readLine();
if (line == null) {
Thread.sleep(1000);
}
else {
MessageConsole console = findConsole("tomcat log");
MessageConsoleStream stream = console.newMessageStream();
stream.println(message);
}
}
}
private MessageConsole findConsole(String name) {
ConsolePlugin plugin = ConsolePlugin.getDefault();
IConsoleManager conMan = plugin.getConsoleManager();
IConsole[] existing = conMan.getConsoles();
for (IConsole element : existing)
if (name.equals(element.getName()))
return (MessageConsole) element;
// no console found, so create a new one
MessageConsole myConsole = new MessageConsole(name, null);
conMan.addConsoles(new IConsole[] { myConsole });
return myConsole;
}
I am making an Eclipse plugin which on right clicking a project produces a UI.
In this UI I have used DirectoryFieldEditor. This produces directory dialog starting at "MyComputer" as root. What i want is it to show paths starting at the project which i right clicked. how can this be achieved?
I am trying to mimic when you right click a project and say "new package" - the source folder browse give a directory dialog with only those folders which are open projects.... I want a similar directory dialog.
Can somebody help and give me some code snippets or suggestions?
Well, considering the "new package" is actually the class:
org.eclipse.jdt.internal.ui.wizards.NewPackageCreationWizard
which uses NewPackageWizardPage (source code), you will see:
public void init(IStructuredSelection selection) {
IJavaElement jelem = getInitialJavaElement(selection);
initContainerPage(jelem);
String pName = ""; //$NON-NLS-1$
if (jelem != null) {
IPackageFragment pf = (IPackageFragment) jelem
.getAncestor(IJavaElement.PACKAGE_FRAGMENT);
if (pf != null && !pf.isDefaultPackage())
pName = pf.getElementName();
}
setPackageText(pName, true);
updateStatus(new IStatus[] { fContainerStatus, fPackageStatus });
}
With the getInitialJavaElement() being part of superclass NewContainerWizardPage:
/**
* Utility method to inspect a selection to find a Java element.
*
* #param selection the selection to be inspected
* #return a Java element to be used as the initial selection, or <code>null</code>,
* if no Java element exists in the given selection
*/
protected IJavaElement getInitialJavaElement(
IStructuredSelection selection) {
IJavaElement jelem = null;
if (selection != null && !selection.isEmpty()) {
Object selectedElement = selection.getFirstElement();
if (selectedElement instanceof IAdaptable) {
IAdaptable adaptable = (IAdaptable) selectedElement;
jelem = (IJavaElement) adaptable
.getAdapter(IJavaElement.class);
if (jelem == null) {
IResource resource = (IResource) adaptable
.getAdapter(IResource.class);
if (resource != null
&& resource.getType() != IResource.ROOT) {
while (jelem == null
&& resource.getType() != IResource.PROJECT) {
resource = resource.getParent();
jelem = (IJavaElement) resource
.getAdapter(IJavaElement.class);
}
if (jelem == null) {
jelem = JavaCore.create(resource); // java project
}
}
}
}
}
if (jelem == null) {
IWorkbenchPart part = JavaPlugin.getActivePage()
.getActivePart();
if (part instanceof ContentOutline) {
part = JavaPlugin.getActivePage().getActiveEditor();
}
if (part instanceof IViewPartInputProvider) {
Object elem = ((IViewPartInputProvider) part)
.getViewPartInput();
if (elem instanceof IJavaElement) {
jelem = (IJavaElement) elem;
}
}
}
if (jelem == null
|| jelem.getElementType() == IJavaElement.JAVA_MODEL) {
try {
IJavaProject[] projects = JavaCore.create(
getWorkspaceRoot()).getJavaProjects();
if (projects.length == 1) {
jelem = projects[0];
}
} catch (JavaModelException e) {
JavaPlugin.log(e);
}
}
return jelem;
}
Between those two methods, you should be able to initialize your custom UI with the exact information (i.e., "relative source path") you want.
If you look at the source of DirectoryFieldEditor, you will see it open its directory chooser dialog based on the value if its main Text field defined in StringFieldEditor:doLoad():
String JavaDoc value = getPreferenceStore().getString(getPreferenceName());
textField.setText(value);
That means you need, in your custom UI, to get the preference store and associate the right path with an id. You will use that id for your DirectoryFieldEditor initialization. Y oucan see an example here.
public static final String MY_PATH = "my.init.path";
IPreferenceStore store = myPlugin.getDefault().getPreferenceStore();
store.setValue(MY_PATH, theRightPath);
myDirFieldEditor = new DirectoryFieldEditor(MY_PATH, "&My path", getFieldEditorParent());
As you mention in the comments, all this will only initialize the eclipse-part GUI, not the native windows explorer launched by a DirectoryDialog:
this (the native interface) is based on:
parameters stored in BROWSEINFO Structure
used by the actual GUI SHBrowseForFolder Function, which actually displays a dialog box that enables the user to select a Shell folder.
That GUI initialize a root path based on filter path, so you need to also initialize (on eclipse side) that filter field with a path in order to get it pick up by the Windows-GUI SHBrowseForFolder.
According to DirectoryFieldEditor, that is exactly what getTextControl() (the field you initialized above) is for.
But the problem comes from the fact that field has been initialized with a relative path. Since that path is unknown by the underlying OS, it defaults back to root OS path.
You need to find a way to store the full system path of the project, not the relative path.
That way, that full path will be recognized by the Os and used as initial path.
For instance, from a IJavaElement, you can get its associated resource, and try to get the (full system) path from there.
Actually, from the IPackageFragment you should be able to call getPath(), and check if the IPath returned contains the full system path.
