我从 github 获取了 XD 源的最新副本并尝试在本地构建。当我运行构建任务时，出现以下错误。我在端口 6379 上运行 Redis。不确定是否缺少其他任何内容。

我的 /etc/hosts 在 Mac 上看起来不错。我必须做一个 -x 测试来跳过测试。任何可能的解决方案？我应该运行 gemfire 吗？

一个奇怪的。我同意，您的 /etc/hosts 看起来不错。我在有时使用 127.0.1.1 而不是 127.0.0.1 的 Linux 机器上看到了这一点。如果您是 GemFire 用户，则测试只是启动一个缓存 new CacheFactory().create();，您可能想检查您的主目录、当前目录或类路径中是否有任何 gemfire.properties 或 cache.xml 文件。GemFire 因发现这些而臭名昭著。

Agreed, your /etc/hosts file appears to be fine (though, I would format it so each host entry is on a single line).

Seems you might running GemFire 7?

Also, what Java vendor/version are you running on your Mac (Apple or Oracle JDK/JRE and version)?

Your version of Mac OS X maybe a factor(???), especially if you have disabled networking (i.e. no "active" NIC, connected with a valid IP, as determined by ifconfig), though this is less than clear.

In a nutshell, GemFire attempts to resolve/lookup the actual IP address of the local system (using GemFire's internal SocketCreator class) when the loopback address is only IP specified (as in your /etc/hosts file), or as returned by InetAddress.getLocalHost().

This resolution process is rather involved and is unfortunately contained within a "static initializer" block inside the SocketCreator class, when the class is loaded.

It seems unlikely that InetAddress.getLocalHost() would ever return null, but in this case the reason why the UnknownHostException in GemFire was thrown was because the SocketCreator.localHost class member variable was null...

310:  public static InetAddress getLocalHost() throws UnknownHostException {
311:    if (localHost == null) {
312:      throw new UnknownHostException();
313:    }
314:    return localHost;
315:  }

The "SocketCreator.localHost" static member variable is initialized inside the static initializer block.

So, either the static initializer was not called or InetAddress.getLocalHost() (possibly because networking was disabled?) returned null, though looking through GemFire's code that would have led to a NullPointerException (that I am uncertain whether might have gotten swallowed somewhere), so it seems more along the lines of the former, but neither answer seems likely, really.

One possible workaround (as it avoided this IP resolution step on startup of GemFire's Membership, as is seen in the stack trace) would be to modify the Spring XD test class, JsonStringToObjectTransformerTests, on line 31, to be...

31:    new CacheFactory().set("mcast-port", "0").set("log-level", "warning").create();

This avoided the SocketCreator.getLocalHost() call from DirectChannel.initAddress(DirectChannel.java:898).

Also, setting the log-level to warn reduces the GemFire noise and significantly speeds up the test.

Hope this helps.
