Java OSHI(操作系统和硬件信息)库NoSuchMethodError

Question

使用OSHI API时收到以下错误(https://github.com/oshi/oshi)。

在我的Maven项目中，我有以下依赖项(我添加了SLF4J来修复基于其他Stack Overflow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>

这就是我使用OSHI:的方式

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：

SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

OSHI 6.2.2需要JNA(Java Native Access(5.12.1，但类路径上似乎有一个旧版本的JNA。在JNA 5.12.0中介绍了CCD_ 1方法。

与mvn dependency:tree一起检查net.java.dev.jna:jna和net.java.dev.jna:jna-platform的依赖项，然后在您自己的POM中(在dependencyManagement中(添加一个显式依赖项，或者将其从拉入旧版本的库中排除，以便拉入OSHI定义的版本。
