NoClassDefFoundError Product when instatiating a new BloomFilter

[il-bert]

Instantiating a simple bloom filter with the following command

    val expectedElements = 10000
    val falsePositiveRate: Double = 0.1
    val bf = BloomFilter[String](expectedElements, falsePositiveRate)

at the last line ( val bf = ...) I am getting the following error

[error] (run-main-0) java.lang.NoClassDefFoundError: scala/Product$class
[error] java.lang.NoClassDefFoundError: scala/Product$class

Thanks for reporting that. Can you specify Java and Scala versions you use please.

Hi, Scala 2.12.6 on jvm 1.8

I got the same error with Scala 2.10.6 and Java 1.8. And fixed via turning the maven dependency scope from 'provided' to 'compile'. Hope this may help.

@il-bert Yes, it could be dependency config related thing. I can't reproduce the issue 😢 . I'll be happy to fix it if you can provide a repro project for it.

I get the same issue. My previouse versions of Scala-library and bloom-filter were inconsistent.But when I set them to be consistent, everything is getting better. Here is my pom.xml

    <dependency>
          <groupId>org.scala-lang</groupId>
          <artifactId>scala-library</artifactId>
          <version>2.10.3</version>
      </dependency>

      <dependency>
          <groupId>com.github.alexandrnikitin</groupId>
          <artifactId>bloom-filter_2.10</artifactId>
          <version>0.11.0</version>
      </dependency>
