Debug

debug的入口在CtsConsole类，所以我们把第一个断点打在249行：

Console console = new CtsConsole();

按F6再按F5进入到Console.startConsole方法中。

按F5进入GlobalConfiguration.createGlobalConfiguration方法中。

该方法内主要是读取全局配置文件并设置IGlobalConfiguration接口对象sInstance。主要方法为95行读取文件的getGlobalConfigPath()：

private static String getGlobalConfigPath() throws ConfigurationException {
        String path = System.getenv(GLOBAL_CONFIG_VARIABLE);
        if (path != null) {
            // don't actually check for accessibility here, since the variable
            // might be specifying
            // a java resource rather than a filename. Even so, this can help
            // the user figure out
            // which global config (if any) was picked up by TF.
            System.err
                    .format("Attempting to use global config \"%s\" from variable $%s.\n",
                            path, GLOBAL_CONFIG_VARIABLE);
            return path;
        }

        File file = new File(GLOBAL_CONFIG_FILENAME);
        if (file.exists()) {
            path = file.getPath();
            System.err.format(
                    "Attempting to use auto detected global config \"%s\".\n",
                    path);
            System.err.flush();
            return path;
        }

        // FIXME: search in tradefed.sh launch dir (or classpath?)

        return null;
    }

if (globalConfigPath != null) {
				// Found a global config file; attempt to parse and use it
				sInstance = configFactory.createGlobalConfigurationFromArgs(
						ArrayUtil.buildArray(new String[] { globalConfigPath },
								args), nonGlobalArgs);
				System.err.format("Success!  Using global config \"%s\"\n",
						globalConfigPath);
			} else {
				// Use default global config
				sInstance = new GlobalConfiguration();
				nonGlobalArgs = Arrays.asList(args);
			}
			return nonGlobalArgs;
