IntelliJ - show where errors are

Question

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".
