Android CTS写日志失败

Question

我已经多次在基于R4的Aurora4.2版本上运行过Android4.2MSMCTS Suite :全套( run cts --plan CTS )或单独的软件包( run cts -p android.acceleration )。这是在Ubuntu12.04LTS64位(使用VMWare融合v6虚拟化)上的

测试套件执行，有时会通过，有时会失败，但随后无法写入日志或生成报告数据：

在CTS /repository/logs & /repository/results目录中，没有新的日志或结果条目。令人惊讶的是，关于CtsXmlResultReporter的信息很少，所以我转向good There‘SO。有人能帮上忙吗？谢谢

这只是一个chmod问题。我需要运行多个版本的CTS ( 4.2，4.3，4.4)，并且我在根目录下创建了4.2目录结构。
