Obtain Inspection output for a given file

Hello everyone,

For the past few days I have been browsing and prototyping with the Inspection API, but to no avail. I am looking for an API to, given a file, obtain all Inspections that IntelliJ shows. In other words, unused imports, unused variables, etc...

I have tried several things thus far, with mixed results:

The following initialization code is available:

final InspectionManagerEx instance = (InspectionManagerEx) InspectionManager.getInstance(project);
GlobalInspectionContextImpl context = (GlobalInspectionContextImpl) instance.createNewGlobalContext(true);
final List<InspectionToolWrapper> inspectionToolWrappers = InspectionToolRegistrar.getInstance().get();
PsiFile file = PsiDocumentManager.getInstance(project).getPsiFile(editor.getDocument()).getOriginalFile();

I run all code snippets below in a block of the following:

ProgressManager.getInstance().runProcess(() -> {
DumbServiceImpl.getInstance(project).runReadActionInSmartMode(() -> {
<snippets here>
}, new EmptyProgressIndicator());

My first attempt was to retrieve the Inspections presentations from the context, however this always returns an empty list.

final List<CommonProblemDescriptor> problems = inspectionToolWrappers.stream()
.flatMap(wrapper -> {
final InspectionToolPresentation presentationOrNull = context.getPresentationOrNull(wrapper);
if (presentationOrNull == null) {
return Stream.empty();
return presentationOrNull.getProblemDescriptors().stream();

Then I tried to the code analyzer on the file, but again an empty list:

final DaemonCodeAnalyzerImpl codeAnalyzer = (DaemonCodeAnalyzerImpl) DaemonCodeAnalyzerImpl.getInstance(project);
final List<HighlightInfo> highlightInfos = codeAnalyzer.runMainPasses(file, editor.getDocument(), progressIndicator);

Then I invoked the LocalInspectionsPass directly, again an empty list:


final LocalInspectionsPass localInspectionsPass = new LocalInspectionsPass(file, editor.getDocument(), 0, editor.getDocument().getTextLength(), file.getTextRange(), true, HighlightInfoProcessor.getEmpty());

My last attempt does return a list, but there are two issues: 1. It is extremely slow and locks up the UI Thread. Putting the logic in a separate Thread throws error of invalid access. 2. It does not seem to return information about the unused import and I do not understand how it maps to the yellow highlighting my editor actually shows. (In the file I tests, I have 2 yellow highlighted errors and 1 unused import, but my list returns like 10 issues)

final List<ProblemDescriptor> problems = inspectionToolWrappers.stream()
.flatMap(wrapper -> InspectionEngine.runInspectionOnFile(file, wrapper, context).stream())

The file I am testing the plugin on. Expected highlighted parts are the `if` and the `!!false` and the `import java.util.List` is grayed out.

import java.util.List;

public class Foo {

public static void main(String[] args) {
if (!!false) {


All in all, my issue seems rather trivial. After indexing and calculation of Inspections (at the moment they are shown in the UI), I would like to obtain these Inspections and the corresponding information.

Could someone help me out pointing to the correct API endpoint to obtain this information?


In all your attempts you run the inspections yourself, I guess it's not what you want. On the other hand you may retrieve already collected data from the model, like:

final MarkupModel markup = DocumentMarkupModel.forDocument(document, project, true);//get markup model by document

RangeHighlighter[] allHighlighters = markup.getAllHighlighters(); //all highlight of the model

for (RangeHighlighter highlighter : allHighlighters) {

if (!highlighter.isValid()) continue;

Object tooltip = highlighter.getErrorStripeTooltip();

if (!(tooltip instanceof HighlightInfo)) {



final HighlightInfo info = (HighlightInfo)tooltip; //contains level of the highlighting (HighlightInfoType), ranges, fixes, etc


Please ensure that you don't leak the model and that you update the view you want to build according to the changes in the document (there are corresponding listeners)




Dear Anna,

Thank you for your response! I did not work during the Christmas vacation, thus my delayed answer.

I just tried it out and it produces the output I expect, much appreciated!
