android - 无法从 Android sdk 工具运行 uiautomatorviewer.bat

Question

我正在尝试从 Android sdk 工具运行 uiautomatorviewer.bat。

它在我以前的系统上运行良好，但现在不行了。

通过更改 *.bat 文件中的最后一行来使其在编辑 *.bat 文件之前运行

call "%java_exe%" "-Djava.ext.dirs=%javaextdirs%" "-Dcom.android.uiautomator.bindir=C:\Android\sdk\tools" -jar %jarpath% %*

现在，当我尝试运行 uiautomatorviewer.bat 时，我看到此错误:

C:\Android\Sdk\tools\bin>uiautomatorviewer
-Djava.ext.dirs=..\lib\x86_64;..\lib is not supported.  Use -classpath instead.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

我正在寻找如何使用 -classpath 的不同解决方案，但没有一个有帮助

这不是 .bat 文件问题。

我遇到了同样的问题，因为我使用的是 Java 10。

当我将 Java 10 降级到 Java 8 时，它再次开始工作。

请记住按照此处的说明设置变量 http://www.automationtestinghub.com/setup-java-environment-variables/ .

我的 uiautomatorviewer 现在运行的 Java 版本是 jdk-8u171-windows-x64.exe。
