Failed to run example for JDBC
Hi all,
I fetched an example from the following link:
https://github.com/apache/calcite/blob/master/core/src/test/java/org/apache/calcite/examples/foodmart/java/JdbcExample.java
But I'm not able to run the code, it says cannot find
*"org.apache.calcite.examples.foodmart.java;
" *and it also shows several other errors. I also checked in the github
repository that the folder "examples" is missing.
Please see attach for the source file and the IDE screenshot (the error
message is in Chinese, but the red color shows the error line).
Thank you,

I read the docs but it seems somehow the Maven version doesn't contain the
require source code.
Thanks for your suggestion.

Oh.
It means you miss dependencies (jar files) required to compile and execute
the code.
I suggest you import Calcite source code (e.g. as explained here:
https://calcite.apache.org/docs/howto.html#setting-up-intellij-idea )
Then IDEA will see all the dependencies, and you will be able to execute
examples.
As you get familiar with the way Calcite feels, you might could create a
standalone project that uses Calcite.

I used the newest version of Intellij on Windows 10 with JDK 11 to run the
code directly.

Thanks Vladimir's reminder in Jira. It seems like Intellij on mac can just
run it without a problem, but the version on linux failed to run the main
class thus I thought there was a missing setup.
My PR then can be used as an example for those who's intellij somehow does
not work then.

I tried to run this example but also got some troubles:
1. Intellij cannot run it directly.
2. "java -cp main_class" was not easy to use. Needed to add some jars to
classpath and it eventually ended up with a "Class Not Found" error.
So I create a gradle task for this example and then it can be as easy as
just running command "./gradlew runJdbcExample". Meanwhile it's also easy
to let intellij run it by this command thus debugger becomes usable for
inspecting what's going on under the execution of this example.

How were you trying to run the code? Note that the mailing list
doesn't accept attachments, so you'll have to upload the screenshot
somewhere and include a link. I'm not sure what you mean when you say
the examples folder is missing from the repository. The link you
included in your message is to a file in the examples folder.
