Compilation error when building Calcite package
Hi Julian,
I was trying to build a Calcite package but got this error. Could you
please tell me how to fix it?

Thanks a lot Julian, for the help! It now works. I tried with different
Java versions but forgot to run "mvn clean". And I think the error had
originally come from Eclipse.
Thanks,
Maryann

It works on jdk 1.7.0_79 also. (And linux and windows.)
Maryann, I googled "Unresolved compilation problem” and it seems to be coming from Eclipse. Are you running Eclipse?

It works for me on 1.7.0_21 on Mac OS (maven 3.1.1, using “mvn clean && mvn install"). Downloading 1.7.0_79 now, to try a more recent version.

Re: Compilation error when building Calcite package
Posted by Maryann Xue <ma...@gmail.com>.
I am working on mac, but have installed an oracle JDK:
java version "1.7.0_72"
Java(TM) SE Runtime Environment (build 1.7.0_72-b14)
Java HotSpot(TM) 64-Bit Server VM (build 24.72-b04, mixed mode)
I also once tried with JDK 1.8 before, but didn't get it right.

What version of Java?
It looks like the kind of error that I get when I use my Mac’s default java (i.e. 1.6).
