I am using IntelliJ IDEA (2016.3) linux version for Java development. As shown in the image below when the mouse pointer hover over an error line, the error message is overlapped by the javadoc making it harder to read the given error message. How to fix this?. Thanks in advance
I use 2017.1.3 EAP on Win10 and it is the same. Seems like a bug.
There are several workarounds:
Set time delay for documentation popup to a higher value. This should give you more time to read the error message. (Settings -> Editor -> General -> Show quick documentation on mouse move).
Set a cursor at the code with the error and you will see a duplicated error message in the status bar.
You can also have the documentation in a fixed spot by clicking the pin in the top right corner of the pop-up. The window will then always be there, but it does update on mouse-overs and it is not over the warning- and errormessages anymore.
This happened to me in Android Studio and I've just removed documentation on mouse hover setting and set a Shortcut Key (Alt+D) for that. This is more comfortable for me.
I am unable to find any error in Intellij even after making mistakes
For example: If i write following statement
String str1 =new String("Shoaib")
It should show red color stating that ; is missing.But it is unable to do so.
I may have change something internally
What i need to do to work above issue
To fix this just disable the power saver mode and add the live edit plugin. When you disable the power saver mode it will automatically prompt in right bottom corner for installing the live edit plugin just click yes on it and restart your intellij, It will work as expected.
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
Everywhere there are pretty pictures of failing tests shown inline in the code editor, like in Peepcodes Objective-C for Rubyist screencast and in apples own technical documentation:

When I build my test-target, all I get is a little red icon down in the right corner, stating something went wrong. When clicking on it, I get the Build Results, where I can start to hunt for test results.
Do anyone have a clue on what´s wrong?
Have a look at your Xcode preferences. Under the Building tab you want to change your settings for Message Bubbles.
This works for Xcode 3.1 which it looks like the image you've shown. Xcode 3.2 has a different style of bubble and doesn't have this preference.
Press "Cmd =" to travel between build results, you should see a warning.
Also, that specific warning seems like it's from the static analyzer - you turn that on by going to project preferences and checkmarking "run static analyzer" or by using the "Build and Analyze" option.
Try Cmd-Shift-H to show all message bubbles.
I'm trying to watch a variable with Xcode. I'm following the instructions in here by pausing at a breakpoint, selecting Run > Variables View > .... but with the exception of "Enable Data Formatters" the rest of the options are all greyed out. Any ideas?
I'm using Xcode version 3.1.3.
I haven't gotten watchpoints created from the Run menu to work for me either, unfortunately. One thing to be aware of is that when a variable goes out of scope, the watchpoint may become invalid.
If you don't mind getting a little more in-depth, you can use some low-level gdb commands to set a watchpoint for the address of the memory itself. For example, in the guide you linked to, they show how to watch the variable path which is a pointer with the value 0xbfffeb70. To manually set a watchpoint for that address, click in the debugger console (where the debugging output is printed) after the "(gdb)" prompt and type something like this:
watch *((int*)0xbfffeb70)
The cryptic syntax is necessary because gdb expects inputs as C expressions. For a little more detail, visit this link and jump to the section titled "Using hardware watchpoints". (I'm testing on an Intel machine, not sure how PowerPC handles it.) When you set watchpoints this way, Xcode will alert you with a drop-down sheet when a watchpoint is reached and tell you how the value was changed, and gdb will print the same info in the console.
I just ran into this problem. Here is a solution: right click on the variable name and select "View variable in window" from the menu which appears. It should be near the bottom.
Add a breakpoint. Right click in the watch list of the debug area and choose "Add expression..."
If you are getting a different menu, you have to click off of the currently highlighted variable so that nothing is highlighted when you right click.
The Answers given here only work if you use the gdb compiler. For those of you who are looking for an option to set a watchpoint with the lldb compiler I have bad news:
It's not working jet (XCode 4.3.2 with lldb 3.1) even though the lldb docs say you can.
Check out this Email. The lldb commands compared to the gdbs can be found here
I was trying to figure this out in XCode 5. I finally found a "Variables view" button at the bottom right of the output console. It's the little rectangle that will be gray on the left, white on the right if it's not enabled. I'm not sure if this is in XCode 3, but I expect most people have upgraded anyway.
