如何获取操作系统上安装的Google Chrome的版本号?

Question

我想写一个硒脚本，可以不需要任何更新的工作。我希望能够运行该程序，并确定当前安装在操作系统上的谷歌Chrome版本(它可以是Windows或Linux)，然后从那里安装兼容的ChromeDriver。

我已经试过了，只是尝试打印值:

public static void chromeVersion() throws IOException {
String installPath = "";
Process userProcess;
BufferedReader usersReader;
if(SystemUtils.IS_OS_WINDOWS) {
installPath = "C:/Program Files/Google/Chrome/Application/chrome.exe";
userProcess = Runtime.getRuntime().exec(installPath + " --version");
usersReader = new BufferedReader(new InputStreamReader(userProcess.getInputStream()));
String p;
while ((p = usersReader.readLine()) != null){
System.out.println(p);
}
}

}

但是它打印一个运行时错误，说找不到路径。即使路径是正确的，我也怀疑这是不是最好的解决方案，因为从技术上讲，从一台Windows计算机到另一台Windows计算机的路径也可能不同。

我还能做些什么来完成这项任务?

编辑:经过进一步的研究，这似乎在Java中是不可能的?想法吗?

编辑:绿巨人在评论中指出我可以这样做:

public static void chromeVersion() throws IOException {
String installPath = "";
Process userProcess;
BufferedReader usersReader;
if(SystemUtils.IS_OS_WINDOWS) {
installPath = "reg query 'HKEY_CURRENT_USER\Software\Google\Chrome\BLBeacon' /v version";
;
userProcess = Runtime.getRuntime().exec(installPath);
usersReader = new BufferedReader(new InputStreamReader(userProcess.getInputStream()));
String p;
while ((p = usersReader.readLine()) != null){
System.out.println(p);
}
}

}

然而，这并不打印任何东西，但如果我从CMD运行reg query "HKEY_CURRENT_USERSoftwareGoogleChromeBLBeacon" /v version，那么我得到这个:

HKEY_CURRENT_USERSoftwareGoogleChromeBLBeacon
version    REG_SZ    93.0.4577.82

我设法使它像这样工作:

public static void chromeVersion() throws IOException {

Runtime rt = Runtime.getRuntime();
Process proc = rt.exec("reg query " + "HKEY_CURRENT_USER\Software\Google\Chrome\BLBeacon " +  "/v version");
BufferedReader stdInput = new BufferedReader(new 
InputStreamReader(proc.getInputStream()));
BufferedReader stdError = new BufferedReader(new 
InputStreamReader(proc.getErrorStream()));
// Read the output from the command
System.out.println("Here is the standard output of the command:n");
String s = null;
while ((s = stdInput.readLine()) != null) {
System.out.println(s);
}
// Read any errors from the attempted command
System.out.println("Here is the standard error of the command (if any):n");
while ((s = stdError.readLine()) != null) {
System.out.println(s);
}

}

这将打印:

Here is the standard output of the command:

HKEY_CURRENT_USERSoftwareGoogleChromeBLBeacon
version    REG_SZ    93.0.4577.82
Here is the standard error of the command (if any):
