IntelliJ错误:发生了JNI错误，请检查您的安装并重试 [英] IntelliJ Error: A JNI error has occurred, please check your installation and try again

问题描述

我试图在intellij中运行一个项目，每次我运行一个特定的类时，都会收到以下错误消息:

*Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/spark/streaming/StreamingContext
    at java.lang.Class.getDeclaredMethods0(Native Method)

解决方案

我遇到相同的问题已经很长时间了，我的代码在执行以下行时引发了相同的错误:

val ssc = new StreamingContext(sc, Seconds(10))

我的POM.xml看起来像这样:

<dependency>
      <groupId>org.apache.spark</groupId>
      <artifactId>spark-streaming_2.11</artifactId>
      <version>2.3.4</version>
      <scope>provided</scope>
</dependency>

您看到附加的行<scope>吗?一旦我从POM文件中删除了这一行，代码便回到了正确的轨道，并成功执行了.

因此，请确保从dependency中删除<scope>.

    <dependency>
        <groupId>org.apache.spark</groupId>
        <artifactId>spark-streaming_2.11</artifactId>
        <version>2.3.4</version>
    </dependency>

I am trying to run a project in intellij and every time I run a particular class, I get the below error message:

*Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/spark/streaming/StreamingContext

解决方案

I was facing the same issue for so long, my code was raising the same error while executing the following line:

val ssc = new StreamingContext(sc, Seconds(10))

my POM.xml looked like this:

<dependency>
      <groupId>org.apache.spark</groupId>
      <artifactId>spark-streaming_2.11</artifactId>
      <version>2.3.4</version>
      <scope>provided</scope>
</dependency>

You see that additional line <scope>? Once I removed that line from my POM file, the code was back on track, successfully executed.

So please make sure you remove the <scope> from the dependency.

    <dependency>
        <groupId>org.apache.spark</groupId>
        <artifactId>spark-streaming_2.11</artifactId>
        <version>2.3.4</version>
    </dependency>
