William1104 opened a new pull request #195: remind developers to reset maven home in IntelliJ
URL: https://github.com/apache/spark-website/pull/195
 
 
   
   I tried to follow the guide at 'http://spark.apache.org/developer-tools.html' to setup an IntelliJ project for Spark. However, the project was failed to build. It was due to missing classes generated via antlr on sql/catalyst project even thought I clicked the 'Generate Sources and Update Folders For All Projects' button in IntelliJ as per suggested.
   
   It turned out that I forgot to reset the maven home in my IntelliJ and the IntelliJ failed the 'Generate Sources and Update Folders For All Projects' action silently. That was why ANTLR4 files were not generated as expected. 
   
   To help other developers, I would like to enhance 'http://spark.apache.org/developer-tools.html' to add a note to remind developer to check if the 'Generate Sources and Update Folders For All Projects' action was failed silently due to incorrect maven version. If so, they should update the maven home in IntelliJ accordingly
