Subject Antlr plugin for sql/catalyst project
Date Sun, 14 Apr 2019 09:15:52 GMT
Dear all,

I tried to follow the guide at ''
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

I would like to enhance the document to hint other new joiners to run
'build/mvn antlr4 -f sql/catalyst/pom.xml' if hitting missing ANTLR4
classes files. However, Spark's project structure is very new to me. I hope
I did not miss any guideline on spark's documentation about this issue, if
so pls let me know. Thanks in advance.
