尝试使用 ml-gradle 插件将现有的 roxy 项目转换为 ml-gradle。这是 build.gradle：

plugins {
   id "net.saliman.properties" version "1.5.1"
   id "com.marklogic.ml-gradle" version "3.1.0"
}

这会产生以下错误：

> Task :mlroxyMigrateProperties FAILED
  Mapping roxy property 'group' to ml-gradle property 'mlGroupName'
  Mapping roxy property 'user' to ml-gradle property 'mlusername'
  Mapping roxy property 'password' to ml-gradle property 'mlPassword'
  Mapping roxy property 'app-name' to ml-gradle property 'mlAppName'
  Mapping roxy property 'content-db' to ml-gradle property 'mlContentDatabaseName'
  Mapping roxy property 'modules-db' to ml-gradle property 'mlModulesDatabaseName'
  Mapping roxy property 'content-forests-per-host' to ml-gradle property 'mlContentForestsPerHost'
  Mapping roxy property 'app-port' to ml-gradle property 'mlRestPort'
  Mapping roxy property 'authentication-method' to ml-gradle property 'mlRestAuthentication'
  Mapping roxy property 'appuser-password' to ml-gradle property 'mlRestAdminPassword'
  Mapping roxy property 'test-port' to ml-gradle property 'mlTestRestPort'

  FAILURE: Build failed with an exception.

  * What went wrong:
   Execution failed for task ':mlroxyMigrateProperties'.
  > Could not get unknown property 'roxyProperties' for task ':mlroxyMigrateProperties' of type com.marklogic.gradle.task.roxy.roxyMigratePropertiesTask.

gradle.properties 没有写入任何内容，因此它根本无法复制任何属性。有什么建议可以让它过去这个错误吗？谢谢
