Fixed it:

<dependency>
        <groupId>com.github.MilkBowl</groupId>
        <artifactId>VaultAPI</artifactId>
        <version>1.7</version>
        <scope>provided</scope>
        <exclusions>
            <exclusion>
                <groupId>org.bukkit</groupId>
                <artifactId>bukkit</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

Only if you use the VaultAPI, you have to exclude org.bukkit. So that we can use it from the original dependency
