我无法构建guava v21.0，因为测试concurrent.ListenerCallQueueTest永远挂起：
$ git clone https://github.com/google/guava
$ cd guava
$ git tag
$ git checkout v21.0
$ mvn package
[...]
Tests run: 11, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 2.177 sec
Running com.google.common.util.concurrent.ListenerCallQueueTest
我似乎有三个睡眠过程：
$ ps aux | grep guava | grep -v grep

我的debian stretch计算机上出现这种情况：
$ uname -a
Linux front 4.8.0-1-amd64 #1 SMP Debian 4.8.5-1 (2016-10-28) x86_64 GNU/Linux
$ mvn -version

同样的程序可以在我的debian jessie机器上成功构建：
Apache Maven 3.0.5
Maven home: /usr/share/maven
Java version: 1.8.0_111, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-8-openjdk-amd64/jre

在this post中找到以下建议后，我已成功完成了构建：
$ mvn clean install -Dmaven.test.skip
但是，运行mvn clean install代替mvn clean package会导致相同的结果。
非常感谢任何建议。
