google-closure-compiler - 隐藏 Google 图书馆的警告

Question

我在我的项目中使用了 Google Closure 和 Google Library，但遇到了警告问题。

我的项目由大约 50 个带有一些小警告(JSDoc 错误)的文件组成。问题是谷歌图书馆，当我编译我的项目时，来自谷歌图书馆的大量警告列表，如下所示:

../Libs/Closure/closure/goog/uri/utils.js:255: WARNING - inconsistent return type
found   : (null|string|undefined)
required: (null|string)
  return uri && decodeURIComponent(uri);
         ^

../Libs/Closure/closure/goog/uri/utils.js:634: WARNING - inconsistent return type
found   : (Array.<(string|undefined)>|undefined)
required: Array.<(string|undefined)>
  return buffer;
         ^

../Libs/Closure/closure/goog/uri/utils.js:671: WARNING - inconsistent return type
found   : (Array.<(string|undefined)>|undefined)
required: Array.<(string|undefined)>
  return buffer;
         ^

../Libs/Closure/third_party/closure/goog/mochikit/async/deferred.js:623: WARNING - assignment to property deferred of goog.async.Deferred.AlreadyCalledError
found   : (goog.async.Deferred|undefined)
required: (goog.async.Deferred|null)
  this.deferred = deferred;
  ^

../Libs/Closure/third_party/closure/goog/mochikit/async/deferred.js:651: WARNING - assignment to property deferred of goog.async.Deferred.CancelledError
found   : (goog.async.Deferred|undefined)
required: (goog.async.Deferred|null)
  this.deferred = deferred;
  ^

我收到了来自 Google 图书馆的 300 多个警告和来自我的项目的约 50 个警告。那么，如何隐藏 google 的库警告并显示我的项目警告？

我尝试使用稳定的 Google 库和 SVN 存储库中的最后一个构建我的项目，但我总是收到所有这些警告。

我的编译配置:

../Libs/Closure/closure/bin/build/closurebuilder.py \
--root=../Libs/Closure/ \
--root=../Projects/myProject/ \
--namespace="Project" \
--output_mode=compiled \
--compiler_jar=../Libs/Closure/compiler.jar \
--compiler_flags="--third_party=../Libs/Raphael/raphaeljs_extern.js" \
--compiler_flags="--compilation_level=SIMPLE_OPTIMIZATIONS" \
--compiler_flags="--warning_level=VERBOSE" \
> ../../Projects/js/project_release.js

谢谢你的时间!

要禁止所有警告消息，您应该使用:
--compiler_flags="--warning_level=QUIET"
而不是 verbose您当前拥有的设置。
