windows – 将exec’d批处理文件中的退出代码传播回ant

<target name="publish-jar">
    <exec executable="sbt.bat" failonerror="true">
      <arg value="publish"/>
    </exec>
  </target>

如果sbt任务失败,我需要ant任务“失败”,这就是使用failonerror =“true”的原因.但是,这不起作用.当sbt任务失败时,ant不会报告失败的构建.

这看起来像这里讨论的问题：Ant exec resultproperty is not working.建议的解决方法是从sbt.bat中删除“/ B”.换句话说,改变：

exit /B %ERROR_CODE%

至

exit %ERROR_CODE%

但是,正如一位评论者所说：

The downside of this is that if you run the batch file directly for testing it will terminate your shell. you could use an if and an arg in the batch file to select b when ant calls it and normal exit when not.

问题：当发生故障时是否有修复：(1)不终止调用者的shell和(2)将退出代码传播给ant？

更新

这是运行我的ant任务的输出.实际错误在这里并不重要(我故意不配置存储库来发布,强制错误)：
