Can't find java file for ImmutableCsvProjectTableScanRule

Hi,

we are trying to make our adapter projectable now,  but we can't find the Java file for the ImmutableCsvProjectTableScanRule class in the CSV example, can you help with this.


/** Rule configuration. */
&nbsp; @Value.Immutable(singleton = false)
&nbsp; public interface Config extends RelRule.Config {
&nbsp;&nbsp;&nbsp; Config DEFAULT = ImmutableCsvProjectTableScanRule.Config.builder()
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .withOperandSupplier(b0 -&gt;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; b0.operand(LogicalProject.class).oneInput(b1 -&gt;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; b1.operand(CsvTableScan.class).noInputs()))
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .build();

&nbsp;&nbsp;&nbsp; @Override default CsvProjectTableScanRule toRule() {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return new CsvProjectTableScanRule(this);
&nbsp;&nbsp;&nbsp; }
&nbsp; }

I believe you need to make sure that the "Immutables" annotations processor
is set up correctly
Like Fan Liya mentioned, that class is generated by the annotations, so you
need to configure Gradle/Maven to process them:

If you haven't already, make sure to enable Annotation Processors in your
IDE settings (I assume IntelliJ?)
https://immutables.github.io/apt.html#intellij-idea

Hope this helps

Hi xiaobo,

It seems 'ImmutableCsvProjectTableScanRule' is a generated class.
You have to build the project first?

Best,
Liya Fan
