java.lang.NoClassDefFoundError: io/netty/handler/ssl/SslContextBuilder

Question

I am trying to implement relayrides/pushy, but am getting the following runtime error:

Jun 28, 2017 2:06:58 PM com.turo.pushy.apns.SslUtil getSslProvider
INFO: Native SSL provider not available; will use JDK SSL provider.
Exception in thread "main" java.lang.NoClassDefFoundError: io/netty/handler/ssl/SslContextBuilder
  at com.turo.pushy.apns.ApnsClientBuilder.build(ApnsClientBuilder.java:396)
  at com.jobs.spring.service.NotificationServiceImpl.sendIOSPushNotification(NotificationServiceImpl.java:122)

  Caused by: java.lang.ClassNotFoundException: io.netty.handler.ssl.SslContextBuilder

java

    final ApnsClient apnsClient = new ApnsClientBuilder()
            .setClientCredentials(new File(PATH_TO_P12_CERT), CERT_PASSWORD )
            .build();

I am guessing my mvn dependencies are incorrect. Any help appreciated.

UPDATE

I updated my dependencies to:

    <dependency>
        <groupId>com.turo</groupId>
        <artifactId>pushy</artifactId>
        <version>0.10</version>
    </dependency>
    <dependency>
        <groupId>io.netty</groupId>
        <artifactId>netty-all</artifactId>
        <version>4.1.11.Final</version>
    </dependency>
    <dependency>
        <groupId>io.netty</groupId>
        <artifactId>netty-tcnative</artifactId>

    <dependency>
        <groupId>com.google.code.gson</groupId>
        <artifactId>gson</artifactId>
        <version>2.6</version>
    </dependency>

But now get:

INFO: Native SSL provider not available; will use JDK SSL provider.

Answer 1

seems like you mix netty 4.1 and 4.0. You need to only use 4.1 if you want to use pushy.
