java.lang.NoSuchMethodError: in redisson and netty integration

I have built my own library of custom methods using redisson 3.4.4. This internally uses netty-all-4.1.13.Final.jar.

When I build my library and try to use with a project I get following exception,

java.lang.NoSuchMethodError: io.netty.bootstrap.Bootstrap.config()Lio/netty/bootstrap/BootstrapConfig;

I did further digging into the "netty-all-4.1.13.Final.jar" and able to find that method "io.netty.bootstrap.Bootstrap.config()" with return type "io/netty/bootstrap/BootstrapConfig" is actually present.

Why am I getting "method not found error" here then if its present in jar/library I am using??

Solution

  • I modified my classpath used for running application to include netty-all-4.1.13.Final.jar before some jars which I felt internally using netty's older version library.

    Solved as of now.
