Locate code author (annotate/blame) in place - intellij-idea

Besides having this "annotate" option on the "Differences Viewer" located on the left side of a class, there is a new feature in IntelliJ for locating code author and commit message in place.
For example, if you have your cursor on some code in Java class, a grey text will be displayed beside the java line of code, containing the Author and his commit message for this line. See image below.

My IntelliJ is up-to-date 2019.2, but I never had this feature. Does someone know how to enable it or get it to work on my workplace?
Many thanks.

This functionality is provided by the GitToolBox plugin.

IntelliJ Plugin Development: LookupElement with class preview

For a custom language I created a CompletionContributor. Everything works fine. But I'm limited to the information I can display (only in the list or the bottom "advertisement" and only 1 line).
When trying to auto-complete on a java class name it will display more information on the selected line in a small side window. I would like to exploit that mechanism but I really don't know how it is done.
When looking at the options provided, I can use a custom LookupElementRenderer but there is no method in LookupElementPresentation related to the right window.
Any idea how it is done?
Are you referring to documentation popup which may be displayed if the corresponding setting (Setting->Editor->General->Code completion->Show the documentation popup in) is turned on?
If you want the feature to work for your language you have to use lang.documentationProvider extension point.

List of all errors in project in CLion

CLion 2016.2 helpfully detects potential errors in the file you're editing, which can be seen in the validation bar to the right of the code.
That's just a single file though, is there a way (like a tool window) to get a list of all such warnings in the whole project, or specific parts of it?
Bonus points if it also lists warnings and errors from the compiler, though that's less important, because the compiler output already includes any it found.
Yes, it is possible. The feature you are looking for is called the Inspector.
Do: Find Action... | Inspect Code. It will show a pop-up that will allow you to select the scope: file, whole project, custom, and the Inspection profile (you can choose the type of errors you want to see):
After clicking OK, this is an example of the output, that you can navigate with the mouse or with keyboard shortcuts:
In version 2017.2, I have it under Code | Inspect Code....
You can also right click a folder in Project view and select Inspect Code... there to be able to check only that folder.

No coverage in 'all classes in scope' in Intellij

In Intellij IDEA 14.1.5 Community edition, I imported maven to get coverage from jacoco.exec file. Steps followed
right click on imported module.
select Analyze-->Show Converage Data.
provided valid jacoc.exec file and click 'show selected'
Instead of coverage i'm getting error as no coverage in 'all classes in scope'
can anybody suggest what is wrong?
I had the same thing happen to me.
I was able to fix this by going to "Edit Configurations", to the "Code Coverage" tab.
I'm not sure what caused it, but the wrong package namespace was listed there. I updated the entry there and my subsequent test run with code coverage succeeded.
It happens if your test class and class to test are in different package structures.
My test class was in:
com.tools.api
Class to be tested was in:
com.tools.ws
Once I've corrected the pattern as com.tools.* in the code coverage tab, I was able to see coverage results.
I had the same problem and found solution here.
In the Code Coverage tab, define the following options:
Specify the scope to measure code coverage for. Do one of the following:
To specify a class, click the Add Class button.
To specify a package, click the Add Package button.
I was able to fix this issue by:
Open Edit Configurations menu
Click on Modify Options > Coverage settings > Specify classes and packages
In the new box that appears, click on the plus to add a package
Select a high level package from the project

CodeLens style in-context information in IntelliJ IDEA

For a while now, newer versions of Visual Studio have been able to display in-line information for methods, fields etc relating to how many times they may have been referenced or changed and who changed the code last. This feature is known as CodeLens.
Is there any plugin or feature in IntelliJ IDEA similar to this that would be able to display information on an individual class/field/method basis?
(22-Aug-2022 updated) The hints from git blame are also available in the latest IntelliJ IDEA.
==================
(For CodeLens function references feature) Now it's a built-in feature after version IntelliJ IDEA 2020.1.
You can enable it from:
Ref: https://blog.jetbrains.com/idea/2020/03/intellij-idea-2020-1-beta2/
There is no such plugin (yet).
You can of course right click the left gutter (gray editor to the left of the editor) and select "Annotate". That gives you at least the last edit per line.
More similar to your desired feature (but unfortunately not inline):
Select some text (e.g. a method), then right-click Git -> Show History for Selection.
Now there is JetBrains plugin named GitToolBox.
It has some similar functionality, including the current line "blame annotation" at the end of the line with detailed commit information:
This feature is available for Rider, but not for IntelliJ yet.
In Rider it's called Code Vision

How to see live list of syntax errors in WebStorm 7 (or IntelliJ)?

While editing a JavaScript file, the IDE shows highlights on the lines that have problems and displays the lightbulb when you're on one of those lines.
How can I see a live list of all problems found in the current file (e.g. syntax errors)?
The only way I found so far was to manually run inspection and check the inspection window. That's quite cumbersome. Even the "Problems" section of the Project window updates itself automatically as soon as I change the code (even without saving) - but it doesn't display the actual errors (only which files have errors).
Apparently the IDE knows what errors exist in the file - I just can't find a way to see all of them in a list.
In every other IDE I know, it is a built-in, enabled-by-default, feature: eclipse, visual studio, brackets, etc.
Apparently this is an open issue on the IntelliJ family of products. Please upvote that issue if you feel it is missing as well!
