'NoSuchMethodError' exception with browsermob-proxy 2.1.0-beta4 - nosuchmethoderror

Question

I'm trying to capture traffic from my mobile device using browsermob-proxy 2.1.0-beta4, but I keep getting a NoSuchMethodError exception that weirdly enough keeps mentioning Google - java.lang.NoSuchMethodError: com.google.common.net.HostAndPort.fromHost
Here's my code (without imports):
public class BrowserMobProxy {
#Test
public void checkConnection() throws JSONException, IOException, InterruptedException {
SMAPLogger.Info("Connecting to Proxy");
BrowserMobProxyServer mProxyServer = new BrowserMobProxyServer();
mProxyServer.start(8888);
// mProxyServer.setHarCaptureTypes(CaptureType.REQUEST_CONTENT);
while (true) {
Thread.sleep(1000);
Har har = mProxyServer.getHar();
if (har != null) {
for (HarEntry entry : har.getLog().getEntries()) {
System.out.print("har");
System.out.print(entry.getRequest().toString());
}
}
}
}
}
And here's the exception I get:
11:39:00.618 [LittleProxy-0-ClientToProxyWorker-4] ERROR org.littleshoot.proxy.impl.ClientToProxyConnection - (AWAITING_INITIAL) [id: 0xf2cbf348, /192.168.100.105:40588 => /192.168.100.101:8888]: Caught an exception on ClientToProxyConnection

Answer 1

You are using an old version of Google Guava.
Browsermob relies on Guava version 17+.
If you are using Maven, add the following to your pom-file (or replace the section if you already have a direct Guava dependency):
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>17.0</version> <!-- Or something newer like 19.0 -->
</dependency>
