You need to remove one of those 2 jars:

```auto
jar1: C:\Users\admin.m2\repository\org\elasticsearch\jna\4.5.1\jna-4.5.1.jar
jar2: C:\Users\admin.m2\repository\net\java\dev\jna\jna\4.5.1\jna-4.5.1.jar

```

Probably this one:

```auto
jar2: C:\Users\admin.m2\repository\net\java\dev\jna\jna\4.5.1\jna-4.5.1.jar

```
