Error saying "Failed resolution of: Ljava/sql/JDBCType"

[yjhan99]

I do not understand why this error keeps happening. I'm not doing anything complicated, I'm just trying to read the iris.arff file. But, the following error occurs in Read.arff line.

java.lang.NoClassDefFoundError: Failed resolution of: Ljava/sql/JDBCType; at smile.data.type.DataType$1.<clinit>(DataType.java:330) at smile.data.type.DataType.isPrimitive(DataType.java:95) at smile.data.type.StructType.lambda$boxed$1$smile-data-type-StructType(StructType.java:107) at smile.data.type.StructType$$ExternalSyntheticLambda3.apply(Unknown Source:4) at java.util.stream.IntPipeline$4$1.accept(IntPipeline.java:261) at java.util.stream.Streams$RangeIntSpliterator.forEachRemaining(Streams.java:110) at java.util.Spliterator$OfInt.forEachRemaining(Spliterator.java:699) at java.util.stream.AbstractPipeline.copyInto(AbstractPipeline.java:485) at java.util.stream.AbstractPipeline.wrapAndCopyInto(AbstractPipeline.java:475) at java.util.stream.AbstractPipeline.evaluate(AbstractPipeline.java:552) at java.util.stream.AbstractPipeline.evaluateToArrayNode(AbstractPipeline.java:263) at java.util.stream.ReferencePipeline.toArray(ReferencePipeline.java:456) at smile.data.type.StructType.boxed(StructType.java:115) at smile.io.Arff.read(Arff.java:405) at smile.io.Arff.read(Arff.java:380) at smile.io.Read.arff(Read.java:129)

DataType.java file is read-only file and cannot be modified by me. Is there anyone who have seen the same error as me or knows the solution?

Can you try JDK 11 or 17?

I've tried but still the same error..

Do you build your software with modules? If so, do you have requires java.sql; in your module-info file?
