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.
This question is related to
java
intellij-idea
compiler-errors
The answer is
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.
A more up to date answer for anyone else who comes across this:
(from https://www.jetbrains.com/help/idea/eclipse.html, ยงAuto-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.
You should disable Power Save Mode
For me I clicked over this button
then disable Power Save Mode
