2.解决方式

注意这里的报错消息 

-Djava.ext.dirs=F:\android-sdk-windows\build-tools\29.0.3\lib is not supported.  Use -classpath instead.
看来是因为-Djava.ext.dirs的问题

那就好办了

请找到android-sdk的文件路径，在\build-tools\29.0.3文件下的d8.bat文件。

打开后，你会在最后一行看到 

call "%java_exe%" %javaOpts% -Djava.ext.dirs="%frameworkdir%" -cp "%jarpath%" com.android.tools.r8.D8 %params%
更改-Djava.ext.dirs=为-classpath。

注意！-classpath后面是有空格，然后再是"%frameworkdir%"

更改后 

call "%java_exe%" %javaOpts% -classpath "%frameworkdir%" -cp "%jarpath%" com.android.tools.r8.D8 %params%
