java – NoSuchMethodError：com. google. common. base. Stopwatch. createStarted()Lcom / google / common / base / Stopwatch

My app is throwing nosuchmethoderror: com google. common. base. Stopwatch. Createstarted() LCOM / Google / common / base / stopwatch error I don't know why, because 16.0 It does contain that class. I've checked it According to my research, it seems that this is a mistake?

I also have this code for reference, but I don't think it's a problem:

FirewallRule rule = new PeriodicFirewallCounterRule(60,TimeUnit.SECONDS,new IpAddressCountingPolicy());
    ((PeriodicFirewallCounterRule)rule).addHandler(new RateLimitationHandler(new UniqueLimitPolicy(10)));
    FirewallFilter firewallFiler = new FirewallFilter(getContext(),list(rule));
    firewallFiler.setNext(ma);

My app is using restlet apipark:

<dependency>
      <groupId>org.restlet.gae</groupId>
      <artifactId>org.restlet.ext.apispark</artifactId>
      <version>${version.restlet}</version>
  </dependency>

When the application's rest API is run and accessed, it throws this exception error:

[INFO] Caused by: java.lang.NoSuchMethodError: com.google.common.base.Stopwatch.createStarted()Lcom/google/common/base/Stopwatch;

Solution

Use the extension org restlet. When ext.apispark, the version of guava dependency retrieved is 16.0 one

I integrated your code and it works well with me No exceptions were thrown

I think the old version of guava comes from another dependency If you use maven, you should determine where the old guava version comes from and possibly add an exclusion to the corresponding dependency I hope it can solve your problem

I hope I can help you, Thierry
