Java (操作系统和硬件信息)库NoSuchMethodError

Question

当使用OSHI (https://github.com/oshi/oshi)时，我会收到以下错误。

我的Maven项目中有以下依赖项(我添加了SLF4J以修复基于其他堆栈溢出帖子的错误，但没有帮助)：

<!-- https://mvnrepository.com/artifact/com.github.oshi/oshi-core -->
<dependency>
    <groupId>com.github.oshi</groupId>
    <artifactId>oshi-core</artifactId>
    <version>6.2.2</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-api -->
<!-- OSHI requires it!-->
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.36</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-simple -->
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
    <version>1.7.36</version>
    <scope>test</scope>
</dependency>

我就是这样使用OSHI的：

package controller;

import oshi.SystemInfo;
import oshi.hardware.CentralProcessor;
import oshi.hardware.HardwareAbstractionLayer;

public class SystemLoad extends Thread {

    public SystemLoad() {
    }

    @Override
    public void run(){
        while(true) {
            SystemInfo si = new SystemInfo();
            HardwareAbstractionLayer hal = si.getHardware();
            CentralProcessor cpu = hal.getProcessor();
            System.out.println( String.valueOf(cpu.getSystemCpuLoad(100)) );
        }
    }
}

这是我收到的错误代码：

OSHI 6.2.2需要JNA () 5.12.1，但看起来类路径上有一个较旧版本的JNA。在JNA5.12.0中引入了Memory.close()方法。

检查mvn dependency:tree为net.java.dev.jna:jna和net.java.dev.jna:jna-platform引入了哪些依赖项，或者在您自己的POM中添加一个显式依赖项(在dependencyManagement中)，或者将它从引入旧版本的库中排除出来，这样OSHI定义的版本就会被拉进来。
