I am using the JDeveloper IDE to build a Java application and, at some point, my error pane has stopped appearing to display compile errors.
When I alter the code to intentionally produce errors during compilation (such as deleting a required parenthesis or brace, etc), I will be informed that there were errors during compilation within the "Messages - Log" window. However, I cannot find the window which describes the errors occuring and their location in the code.
Basically, I just want to access the window that lists the errors found, what class they are located in and what line or method they are in. How do I do this?
Try from menu Window > Reset Windows to Factory Settings.

ActiveX DLL project - running it or Menu > File > Generate Dllname.dll... both produce the error message: Error loading DLL
However, if I open a specific form in design mode then I can compile or run the project without problem.
The form has a MSCAL.OCX v11 Calendar inside.
Note that if I open any other object (classes, forms, etc) continue with the error when try to Run/Compile. Is mandatory to open the frmDate.frm object if I want to Run/Compile the project.
I don't understand why it has this strange behavior and if there is a way to solve it.
Do you have proper appointed the startaup point of the project?
You can do this using this path above:
Go to “Project”->” Properties “, and in the “General” tab select the appropriate form from the “Startup Object” list box.
I'm using IntelliJ IDEA 12. When I run "make project", "debug" or "run" task it does some compiling, shows little bubble that there are warnings, shows grayed-out tool window "message" and after few seconds it hides the nameplate of messages window.
Why is compile log missing? What to do to fix this? I'd like to see (in IDE) what causes those warnings...
PS: I'm not sure, but it might started doing this when I started using Scala (it's now a mixed Scala-Java project).
If you've previously selected "Hide Warnings" then the Messages window is unavailable if there are no compilation errors. It is not even possible to show the empty window using View->Tool Windows-> Message or Alt-0.
Solution:
introduce a compilation error
build, the Messages window should reappear to show your error (or at least be accessible via the View menu)
go to the Messages window and deselect Hide Warnings
fix the compilation error
Rebuild Project and all your warnings will be visible
(I had the same symptoms on 13.0.2 and this worked for me)
For me, it pops up on "Rebuild Project". Maybe that helps.
The window should be there any time IDEA compiles the code. (If there is a not a code change, and you rerun something there is no compiling done and the message window will not show). It is accessible (by default) via Alt+0 (Zero, not the letter 'Oh') or via View > Tools Windows > Messages
You may have a combination of some tool window settings causing this.
If all the tool window buttons are hidden, the messages tool window will be as well. You can toggle this setting via View > Tool Button or the icon in the very bottom left corner of the IDE. To temporarily show the buttons when hidden, hit the Alt twice, holding it down on the second hit.
If the messages tool window is not set to "Docked Mode" and "Pinned Mode" it will close after the compile.
If the above is not the issue, make sure you are using the latest version of IntelliJ IDEA, v12.1.6, and the latest version of the scala plug-in, v0.22.302 (Go to Settings > [IDE Settings] > Plugins and look for the scala plug-in). Those versions work as expected for me.
Looks like u do not have any errors and warnings! In this case in Idea "Messages" tool window auto disappears. I hade the same issue and passes half an hour to understand the reason!
In Eclipse, when I make any code changes it automatically shows all compilation errors in the workspace in a console. It seems like in IntelliJ I have to make/build the project in order to see any compilation errors. Is there a window/tab to show all compilation errors?
Nowadays you have the same option as in eclipse to have automatic builds when you save.
Edit
Any changes in the editor will now trigger a compilation either when Ctrl+s is pressed or after a short interval.
This first image will show a main method and a class with a simple print method. No compilation errors.
In the next image I have removed the parameter message in the print method. That's the only thing I did, I did not even save I just waited a couple of seconds. And then suddenly the compilation error is shown below because the caller of the method has now supplied too many arguments.
Is there a way to make IntelliJ mark error locations continuously for the files you are working on in the similar manner as Eclipse does? At the moment I need to make the project which lists all the errors in the message panel, but even then I cannot navigate to them using the editor panel. I would like to have simple dots/markers which would point to error/warning locations.
IntelliJ IDEA detects errors and warnings in the current file on the fly (unless Power Save Mode is activated in the File menu).
Errors in other files and in the project view will be shown after Build | Make and listed in the Messages tool window.
For Bazel users: Project errors will show on Bazel Problems tool window after running Compile Project (Ctrl/Cmd+F9)
To navigate between errors use Navigate | Next Highlighted Error (F2) / Previous Highlighted Error (Shift+F2).
Error Stripe Mark color can be changed here:
For those who even yet have the problem, try enabling "Build project automatically" in the Java compiler settings and see if that makes a difference as it worked for me.
I ran into the problem of not having set my sources root folder (project window--right click folder, mark directory as > sources root). If you don't set this IDEA doesn't parse the file.
For IntelliJ 2017:
Use "Problem" tool window to see all errors.
This window appears in bottom/side tabs when you enable "automatic" build/make as mentioned by #pavan above (https://stackoverflow.com/a/45556424/828062).
To access this Problems panel, you must set your project to build automatically. Check the box for Preferences/Settings > Build, Execution, Deployment > Compiler > Build project automatically.
Frankly the errors are really hard to see, especially if only one character is "underwaved" in a sea of Java code. I used the instructions above to make the background an orangey-red color and things are much more obvious.
In IntelliJ Idea 2019 you can find scope "Problems" under the "Project" view. Default scope is "Project".
Besides, you can choose going to next error only (ignore warning) by:
Right click the Validation Side Bar.
On the context menu, choose the Go to high priority problems only
it works for Intellij Idea 12
In my case, I unknowingly unchecked 'Error Stripe Mark' option (Idea 2018.2: Settings > Editor > Color Scheme > General and expand `Error and Warnings' & click 'Error').
Fix is to check 'Error Stripe Mark' option of 'Error' (as highlighted in the below image). Now you will see the error marks in scrollbar area.
In my case, IntelliJ was simply in power safe mode
Do you have a yellow icon like this [_] at the bottom of the main window?
It is a "type-aware highlighting" switch which could be disabled accidentally.
You should re-enable it by clicking on the icon.
In the intellij hit ctrl+alt+shift+s and go to global libraries and click on plus icon to add the java libraries this will solve your problem. now you will see the errors coming up
enter image description here
This is the solution I found:
Open IntelliJ Setting (Crtl + Shift + A);
Click in "Editor";
Click in "Color Scheme" + the Programming Language (inside "Color Scheme");
Select "Analysis Error";
Select "Error stripe mark" + Add the Color desired
I'm working with Intellij Idea 10 and Java 6 JDK Update 7. When I run Build --> Rebuild Project command, and the (javac) compilation generates warnings, Idea doesn't display what those warnings exactly are in the Messages view. I just see an "Information: XX warnings" node, but no way to expand it to see the actual warnings. Or I just see a message "Compilation completed successfully with XX warnings" on the status bar. For errors, Idea displays the error information (error message, filename, line number etc.) automatically. How can I get it to work similarly with warnings?
(For the record, I've already tried using additional command line parameters such as -Xlint, but it does not make a difference.)
Make sure that "Hide Warnings" option is disabled in the Messages panel on the left:
