Hello everyone, I want to use javacpp arrow to read parquet files, but I can't find an example, so I'm going to try to implement it myself, but I found that some classes are not found:

all classes in package org.bytedeco.parquet not exists, why?

pom.xml:

    <groupId>org.example</groupId>
    <artifactId>untitled</artifactId>
    <version>1.0-SNAPSHOT</version>

    <properties>
        <exec.mainClass>com.example.RowWiseConversionExample</exec.mainClass>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.bytedeco</groupId>
            <artifactId>arrow-platform</artifactId>
            <version>6.0.1-1.5.8</version>
        </dependency>
    </dependencies>
    <build>
        <sourceDirectory>.</sourceDirectory>
    </build>

BTW, there is a parquet package in the source code
