“Unresolved reference: DataFrame” in Kotlin typically arises when the compiler cannot find the DataFrame class or its associated functions. This often occurs due to missing dependencies or incorrect imports. To resolve this, one can ensure that the necessary library is added to the project and that the correct import statement is used.

Here’s how to address the issue:

  • Add the Kotlin DataFrame library dependency:
    • If using Gradle, add the following line to the dependencies block in your build.gradle.kts file:

தீர்வு
dependencies {
implementation(“org.jetbrains.kotlinx:dataframe:0.9.0”) // Use the latest version
}

  • If using Maven, add the following to your pom.xml file:

    ** **
    ** org.jetbrains.kotlinx**
    ** dataframe**
    ** 0.9.0 **
    ** **
    ** **

“Unresolved reference: DataFrame” in Kotlin typically arises when the compiler cannot find the DataFrame class or its associated functions. This often occurs due to missing dependencies or incorrect imports. To resolve this, one can ensure that the necessary library is added to the project and that the correct import statement is used.
Here’s how to address the issue:
• Add the Kotlin DataFrame library dependency:
◦ If using Gradle, add the following line to the dependencies block in your ----(build.gradle.kts) file:

dependencies {
    implementation("org.jetbrains.kotlinx:dataframe:0.9.0") // Use the latest version
}

If using Maven, add the following to your pom.xml file:

<dependencies>
    <dependency>
        <groupId>org.jetbrains.kotlinx</groupId>
        <artifactId>dataframe</artifactId>
        <version>0.9.0</version> <!-- Use the latest version -->
    </dependency>
</dependencies>

step 7:
copy and past the dependencies to the → build.gradle.kts file

step 8:
click the synchronic gradle changes icon.

Step 9:
it’s start the indexing process.

Step 10:
now the probleam is solved.
