这是什么意思

在提交issue之前，我们应该先查询是否已经有相关的issue和ReadMe中的注意事项，比如说Robust在0.3.3版本才支持windows开发。提交issue时，我们需要写明issue的原因，最好可以携带编译或运行过程的日志或者截图。issue最好以下面的格式提出：

异常类型：编译异常

Robust版本：如:0.4.90

Gradle版本：5.1.1

系统：win 10

堆栈/日志：

dx --dex [--debug] [--verbose] [--positions=<style>] [--no-locals]
[--no-optimize] [--statistics] [--[no-]optimize-list=] [--no-strict]

[--multi-dex [--main-dex-list= [--minimal-main-dex]]
[--input-list=]
[.class | .{zip,jar,apk} | ] ...
Convert a set of classfiles into a dex file, optionally embedded in a
jar/zip. Output name must end with one of: .dex .jar .zip .apk or be a directory.
Positions options: none, important, lines.
--multi-dex: allows to generate several dex files if needed. This option is
exclusive with --incremental, causes --num-threads to be ignored and only
supports folder or archive output.
--main-dex-list=: is a list of class file names, classes defined by
those class files are put in classes.dex.
--minimal-main-dex: only classes selected by --main-dex-list are to be put in
the main dex.
--input-list: is a list of inputs.
Each line in must end with one of: .class .jar .zip .apk or be a directory.
dx --annotool --annotation= [--element=]
[--print=]
dx --dump [--debug] [--strict] [--bytes] [--optimize]
[--basic-blocks | --rop-blocks | --ssa-blocks | --dot] [--ssa-step=]
[--width=] [.class | .txt] ...
Dump classfiles, or transformations thereof, in a human-oriented format.
dx --find-usages <file.dex>
Find references and declarations to a field or method.
declaring type: a class name in internal form, like Ljava/lang/Object;
member: a field or method name, like hashCode
dx -J ... <arguments, in one of the above forms>
Pass VM-specific options to the virtual machine that runs dx.
dx --version
Print the version of this tool (1.10).
dx --help
Print this message.

Start with the README's version and Windows notes and the submitted dx log. Verify which Robust and Gradle versions and operating system produced the error, then trace the build entry point that invokes dx. Done means identifying the cause and documenting a reproducible next step.
