I am using Intellij IDEA Community Edition 2017.2.5. I am writing a spark application using maven as packet manager. My problem is that run time errors don't get displayed.
For eg. Say the entered url was http://localhost:4567/query?type=imnrs
Some where in the code if I have:
request.queryParams("type1"); // tried to get type parameter but a typo occured
Here type1 parameter is not present in the url. So, error must be displayed while running the code. But the error does not get displayed. So, I have to print in every single line to find the error.
The compilation errors get displayed perfectly well. Syntax errors also get highlighted.
A warning get displayed related to logger:
log4j:WARN No appenders could be found for logger (spark.staticfiles.StaticFilesConfiguration).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
Is this the reason for not displaying the error?
I have also tried compiling the project from the terminal and running. Run Time errors don't get displayed that way also.
I use Run window. I also tried looking at event window. I have also tried to invalidate caches. But it didn't work either.
I have already googled to find the answer but was unsuccessful.
