I am looking for a way to view all compile errors in IntelliJ, similar to how they are displayed in Eclipse. I tried searching here and Google but have not really found a solution. I really like IntelliJ, I recently converted to it from Eclipse, and I hope this is just something I am missing and not a fundamental deficiency.

I think this comes closest to what you wish:

(From IntelliJ IDEA Q&A for Eclipse Users):

enter image description here

The above can be combined with a recently introduced option in Compiler settings to get a view very similar to that of Eclipse.

Things to do:

  1. Switch to 'Problems' view in the Project pane:

    enter image description here

  2. Enable the setting to compile the project automatically :

    enter image description here

  3. Finally, look at the Problems view:

    enter image description here

Here is a comparison of what the same project (with a compilation error) looks like in Intellij IDEA 13.xx and Eclipse Kepler:

    Plugin "Eclipse Mode" not available for IDEA 13. – GarfieldKlon Mar 26 '14 at 10:56

    Apparently this "problems" toolbar is only available if you select the "auto compile" mode. see here: https://www.jetbrains.com/help/idea/2016.2/problems-tool-window.html – atom88 Nov 18 '16 at 21:17

    I switched to problems instead of projects and I also enabled the 'Build project automatically' but I still don't see the problems/ compiler errors per se. I just see the classes that have the errors. Could anyone help with that...? – Crenguta S May 17 '17 at 09:29
  • Does this work _at all_ for Scala? I can't seem to make it happen. – conny Mar 09 '18 at 12:30

    Unfortunately, this only shows compilation errors, it doesn't show warnings etc like Eclipse does. Also, the window cant be moved, so when you view problems (aka compilation errors), you cant view your project. – John Little Mar 18 '19 at 09:47
  • Where do you find the "View as Combox of the Project view" option? – efie Oct 11 '20 at 12:55

    This does not work 100% of the time. I only get some errors. – mjs Apr 13 '21 at 11:22

A more up to date answer for anyone else who comes across this:

(from https://www.jetbrains.com/help/idea/eclipse.html, §Auto-compilation; click for screenshots)

Compile automatically:

To enable automatic compilation, navigate to Settings/Preferences | Build, Execution, Deployment | Compiler and select the Build project automatically option

Show all errors in one place:

The Problems tool window appears if the Make project automatically option is enabled in the Compiler settings. It shows a list of problems that were detected on project compilation.

Use the Eclipse compiler: This is actually bundled in IntelliJ. It gives much more useful error messages, in my opinion, and, according to this blog, it's much faster since it was designed to run in the background of an IDE and uses incremental compilation.

While Eclipse uses its own compiler, IntelliJ IDEA uses the javac compiler bundled with the project JDK. If you must use the Eclipse compiler, navigate to Settings/Preferences | Build, Execution, Deployment | Compiler | Java Compiler and select it... The biggest difference between the Eclipse and javac compilers is that the Eclipse compiler is more tolerant to errors, and sometimes lets you run code that doesn't compile.

    Sadly this doesn't help with Android projects, probably because compilation is deferred to gradle. There's an IntelliJ feature request for this here: https://youtrack.jetbrains.com/issue/IDEA-68854 – NeilS Feb 01 '18 at 18:03
  • To initially access the 'settings' - CTRL+ALT+S (or File > Settings) – Chris Halcrow May 22 '19 at 00:18
  • not working. it underlines the classes in project view, but does not show any item in Problems view – Daniel Hári Oct 22 '21 at 19:29

On my system (IntelliJ Idea 2017.2.5), it was not sufficient to enable "Make Project Automatically". I also had to use the menu item "View, Tool Windows, Problems" to see the problems tool window at the bottom of the screen.

the "problem view" mentioned in previous answers was helpful, but i saw it didn't catch all the errors in project. After running application, it began populating other classes that had issues but didn't appear at first in that problems view.

I my case I didn't set Source Root at the src folder. I make a typo to set as Resources Root. after fix it by right click at src folder > Mark Directory as > Source Root, the compile error shows.

  1. Step One : Open Problems View(Alt+6)
  2. Step Two : Enable Wide-View (Top of View Options)
  3. Step Three : In tab Project Errors Click Snipp and Analyze Your project for finding any Problems Cat by File Type And Other Stuff that Programmers need!
