Answer 1

for me worked just this way

<dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt</artifactId>
        <version>0.9.1</version>
    </dependency>

without specifying compile or whatever time

Answer 2

Try rebuilding the project using

Select Build->Rebuild Project

might solve the issue.
