java.lang.NoClassDefFoundError：com / google / common / io / NullOutputStream

Question

我刚刚开始学习NetApp SDK，并尝试运行NetApp创建的第一个示例。 我收到以下错误，我不知道为什么会有与com / google / common / io / NullOutputStream相关的东西

Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/io/NullOutputStream

public class getSystemMode {

    if (args.length < 3) {
        System.err.println("Usage: SystemMode <storage-system> <user> <passwd>");;
        System.exit(1);
    }

    try {
        ApiRunner runner = new ApiRunner(ApiTarget.builder()

            .withHost(args[0])
            .withUserName(args[1])
            .withPassword(args[2])
            .withTargetType(TargetType.FILER)
            .useHttp()
            .build());

        SystemGetVersionRequest req = new SystemGetVersionRequest();
        SystemGetVersionResponse resp = runner.run(req);

        if (resp.isClustered() != null && resp.isClustered()) {
            System.out.println("The storage system " + args[0] + " is in \"Cluster-Mode\"");
        } else {
            System.out.println("The storage system " + args[0] + " is in \"7-Mode\"");
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

}

NullOutputStream已从Guava 15中删除。

请改用ByteStreams.nullOutputStream() 。 计划在Guava 15.0版中删除此类。

您必须查看您的番石榴版本。
