Solution: This happens if eddsa.xxx.jar is missing from classpath. Please add below dependencies in your project if you are using maven:

<!-- https://mvnrepository.com/artifact/net.i2p.crypto/eddsa -->
<dependency>
    <groupId>net.i2p.crypto</groupId>
    <artifactId>eddsa</artifactId>
    <version>0.1.0</version>
</dependency>

• Otherwise google eddsa.version.jar and download and include in your project.
