Question

I am preparing spring-boot application. Then I got the following error:

JNA not found. native methods will be disabled.
java.lang.ClassNotFoundException: com.sun.jna.Native

I am using swagger, elasticsearch, mariadb and maven for my project.

Answer 1

I have solved this issue by adding jna jar file.

<dependency>
    <groupId>net.java.dev.jna</groupId>
    <artifactId>jna</artifactId>
    <version>4.2.2</version>
</dependency>
