spring boot - Correct the classpath of your application so that it contains a single, compatible version of io.jsonwebtoken.SignatureAlgorithm

Question

I have an issue. Tried to change the versions (like it says on the internet), but it didn't help.I get this error when i try to deploy project using docker composer

Problem:

The method's class, io.jsonwebtoken.SignatureAlgorithm, is available from the following 
 locations:
jar:file:/app/libs/jjwt-0.9.1.jar!/io/jsonwebtoken/SignatureAlgorithm.class
jar:file:/app/libs/jjwt-api-0.11.2.jar!/io/jsonwebtoken/SignatureAlgorithm.class
It was loaded from the following location:
    file:/app/libs/jjwt-0.9.1.jar

Console:

---

APPLICATION FAILED TO START

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

io.jsonwebtoken.security.Keys.hmacShaKeyFor(Keys.java:84)

The following method did not exist:

io.jsonwebtoken.SignatureAlgorithm.getMinKeyLength()I

The method's class, io.jsonwebtoken.SignatureAlgorithm, is available from the following locations:

jar:file:/app/libs/jjwt-0.9.1.jar!/io/jsonwebtoken/SignatureAlgorithm.class
jar:file:/app/libs/jjwt-api-0.11.2.jar!/io/jsonwebtoken/SignatureAlgorithm.class

It was loaded from the following location:

file:/app/libs/jjwt-0.9.1.jar

Action:

Correct the classpath of your application so that it contains a single, compatible version of io.jsonwebtoken.SignatureAlgorithm

This is my pom.xml :

<dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt-impl</artifactId>
        <version>0.11.2</version>
        <scope>runtime</scope>
    </dependency>

    <dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt-jackson</artifactId>
        <version>0.11.2</version>
        <scope>runtime</scope>
    </dependency>

    <dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt</artifactId>
        <version>0.9.1</version>
    </dependency>-->
    <dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt-api</artifactId>
        <version>0.11.2</version>
    </dependency>

According to the documentation you only need the following dependencies:

<dependency>
    <groupId>io.jsonwebtoken</groupId>
    <artifactId>jjwt-impl</artifactId>
    <version>0.11.2</version>
    <scope>runtime</scope>
</dependency>

<dependency>
    <groupId>io.jsonwebtoken</groupId>
    <artifactId>jjwt-jackson</artifactId>
    <version>0.11.2</version>
    <scope>runtime</scope>
</dependency>

<dependency>
    <groupId>io.jsonwebtoken</groupId>
    <artifactId>jjwt-api</artifactId>
    <version>0.11.2</version>
</dependency>

The missing class / method is Jwts.parserBuilder() still available but was probably moved between versions. Removing the import from the class and allowing your IDE to reimport it, should resolve this issue.
