java - 线程“main”中的异常java.lang.NoSuchFieldError:JAVA_VENDOR

当我尝试在AWS S3上创建存储桶时，出现以下错误：
线程“主”中的异常java.lang.NoSuchFieldError：JAVA_VENDOR
    在software.amazon.awssdk.core.internal.util.UserAgentUtils.userAgent（UserAgentUtils.java:87）
    在software.amazon.awssdk.core.internal.util.UserAgentUtils.initializeUserAgent（UserAgentUtils.java:73）上。

我有openjdk 11； java -version命令的结果

openjdk version "11.0.1" 2018-10-16
OpenJDK Runtime Environment 18.9 (build 11.0.1+13)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.1+13, mixed mode)

mvn -version命令的结果：... Apache Maven 3.5.4 ...

这是我的pom文件：

从aws创建一个简单的bucket示例

import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.s3.S3Client;
import software.amazon.awssdk.services.s3.model.CreateBucketConfiguration;
import software.amazon.awssdk.services.s3.model.CreateBucketRequest;

public class Main {


    public static void main(String[] args) {
        System.setProperty("JAVA_VENDOR","Oracle Corporation");

        Region region = Region.US_WEST_2;
        S3Client s3 = S3Client.builder().region(region).build();
        String bucket = "bucket" + System.currentTimeMillis();
        CreateBucketRequest createBucketRequest = CreateBucketRequest
                .builder()
                .bucket(bucket)
                .createBucketConfiguration(CreateBucketConfiguration.builder()
                        .locationConstraint(region.id())
                        .build())
                .build();
        s3.createBucket(createBucketRequest);
    }
}

我为赢得它付出了一些努力：
1）试试这个：System.setProperty("JAVA_VENDOR","Oracle Corporation");，
因为真正的系统属性具有中庸的“ java.vendor”
2）我在software.amazon.awssdk.core.internal.util.UserAgentUtils.userAgent中发现了问题所在：它从software.amazon.awssdk.utils.JavaSystemSettings调用JAVA_VENDOR

.replace("{java.vendor}", sanitizeInput(JavaSystemSetting.JAVA_VENDOR.getStringValue().orElse(null)))

但是，JavaSystemSettings类中没有具有该名称的字段。
我该如何处理？

TR; DR更新！
它适用于我的下一个maven pom文件：

最佳答案

NoSuchFieldError是由加载类时版本不匹配引起的。

（设置属性不能解决此问题。异常是指类的字段，而不是Properties对象中的属性。）


  但是JavaSystemSettings类中没有这样名称的字段。


究竟！包含UserAgentUtils类和JavaSystemSettings类的JAR之间版本不匹配。
