我在 IntelliJ IDE 中运行 HbaseTestingUtility 时遇到问题，我可以看到以下错误可能是由于文件名太长造成的：

知道吗，我如何指定 Hbasetestingutility 的基目录而不使用这个庞大的起始目录？

谢谢，

我有一个简单的单元测试，我想针对HBaseTestingUtilityMiniCluster运行。HBaseTestingUtility缺少运行测试所需的传递依赖项。我一直在跟踪NoClassDefFoundErrors并遇到了一些可能是其中一个 jar 文件的打包错误的问题。这是错误：

java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/test/MetricsAssertHelper at org.apache.hadoop.hbase.MiniHBaseCluster.<init>(MiniHBaseCluster.java:91)

当我在项目的 .jar 文件中搜索 MetricsAssertHelper 时，我在 META-INF/services 目录下找到了该文件：

jar tvf org/apache/hbase/hbase-hadoop2-compat/1.0.0/hbase-hadoop2-compat-1.0.0-tests.jar | grep MetricsAssertHelper 53 Sat Feb 14 19:43:40 MST 2015 META-INF/services/org.apache.hadoop.hbase.test.MetricsAssertHelper 1337 Sat Feb 14 19:43:40 MST 2015 org/apache/hadoop/hbase/test/MetricsAssertHelperImpl$MockMetricsBuilder.class 3743 Sat Feb 14 19:43:40 MST 2015 org/apache/hadoop/hbase/test/MetricsAssertHelperImpl$MockRecordBuilder.class 6689 Sat Feb 14 19:43:40 MST 2015 org/apache/hadoop/hbase/test/MetricsAssertHelperImpl.class

然而，这不是 .class 文件。我想知道MetricsAssertHelper.class.jar 文件中是否缺少该文件，因为那里有一个“MetricsAssertHelperImpl.class 文件”。

这是我的代码和 mvn 依赖项。错误发生在HBaseTestingUtility.startMiniCluster()通话中。

    private static HBaseTestingUtility utility;
