    <    artifactId>adventure-api</artifactId>
    <    version>4.12.0</version>
    </    dependency>
    in pom.xml, startup error disappeared, but when i try open plugin menu with command, it's throws an exception:

    It cant find method in new dependency that i specify, but i cant just remove it, because plugint wan't start without it. I trying to slove this problem about 5 hours, and there are no option to slove all of this problems.
    There is my project code:

    you are using papermc in your pom:
    Code:
            <dependency>
            <groupId>com.destroystokyo.paper</groupId>
            <artifactId>paper-api</artifactId>
            <version>1.16.5-R0.1-SNAPSHOT</version>
            <scope>provided</scope>
        </dependency>
    what server are you running? you need to run a papermc server if you write a papermc plugin
