运行嵌入式ElasticSearch时权限被拒绝异常

Question

我正在使用https://github.com/allegro/embedded-elasticsearch编写Elastic的集成测试。初始设置后，当我运行测试时，此插件成功下载了弹性实例，但开始出现权限被拒绝的错误。

我的Java版本：

openjdk 11.0.2 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)

我的嵌入式弹性配置

@BeforeClass
public static void setup() {
 final EmbeddedElastic embeddedElastic = EmbeddedElastic.builder()
 .withElasticVersion("6.6.0")
 .withSetting(PopularProperties.TRANSPORT_TCP_PORT, "9200")
 .withSetting(PopularProperties.CLUSTER_NAME, "partner_portal_elasticsearch_cluster")
 .withPlugin("analysis-stempel") // Commented this line, with this line permission deined came while installing the plugin
  .build();

     try {
         embeddedElastic.start();
        System.out.println("Embedded Elastic Search instance started................");
     } catch (IOException e) {
         e.printStackTrace();
     } catch (InterruptedException e) {
        e.printStackTrace();
     }
  }

ElasticSearch bin文件夹如下所示（供参考）
